HomeBrew command Note

chenchih — Sun, 21 Sep 2025 07:08:28 +0000

I’d like to share some brew commands. This command is used on macOS, similar to winget on Windows, and allows you to download packages or tools

Install Homebrew

Please refer to this link to install Homebrew. Just copy and paste the command into your terminal, and it will install automatically. You need to complete this step; otherwise, you won’t be able to use the brew command

brew command for cli tools

brew command is use to installs CLI tools / libraries / packages.

syntax: brew install <pkg>

Below are some of the commonly use and example of using brew to install

brew install git
brew install python
brew install node
brew install wget

list installed tool:

brew list

uninstall installed tool

brew uninstall git

brew clask for application

Installs GUI/macOS applications (things you’d normally drag into /Applications)

Casks are built into Homebrew core.

syntax: brew install --cask <app>

install other applciation

brew install --cask iterm2
brew install --cask google-chrome
brew install --cask visual-studio-code
brew install --cask slack

List installed casks:

brew list --cask

search applications

brew search <name>
#ex:
brew search iterm2

uninstall application

brew uninstall --cask iterm2

Dedeprecated (not support)

No need to tap

Before (old Homebrew, pre-2020) install like this using use tap like below

brew tap caskroom/cask
brew cask install <app>

compare using brew and web to download:

Website download = manual management (install/update/uninstall yourself).
Homebrew cask = automated management (install/update/uninstall with commands).

Website download

Pros

Always the latest official release direct from the developer.
No dependency on Homebrew.

cons

Manual updates → you have to check for new versions yourself.
Harder to uninstall completely (you need to delete app + configs manually).

brew

Pro

Easy updates with brew upgrade (brew checks and installs new versions).
Scriptable → useful for setting up a new Mac quickly

Cons

Sometimes the version in Homebrew can lag behind the website by a few hours/days.
Requires Homebrew to be installed.

CLI tool → brew install

GUI app → brew install --cask

Setup GenieACS under Ubuntu24.04

chenchih — Tue, 19 Aug 2025 00:55:25 +0000

Setup GenieACS

There are many setup tutorials on setup genieacs on internet; however, some of them use the 20.04 Ubuntu version. I like to show using 22.04 on some settings, some of the configure are different, especially with the MongoDB and genieacs configure.

I have write an automation script to run it without setting it, which support ubuntu 20.04, 22.04, and 24.04. The biggest difference between different versions of Ubuntu is libssl and mogodb version. Please referto this link for the script.

Environment

HW: Raspberry Pi 5
OS: Ubuntu 24.04 ARM

Check Ubuntu Version

lsb_release -a

Check Kernel

uname -ar

Check HW

check model

cat /proc/device-tree/model
#or
cat /proc/cpuinfo | grep 'Model'

Check CPU type

lscpu

Setup

1. Install node.js

curl -sL https://deb.nodesource.com/setup_14.x -o nodesource_setup.sh
sudo bash nodesource_setup.sh
sudo apt install nodejs
node -v

2. Install MongoDB

Note: In Ubuntu 24.04 the SSL default uses libssl3, so you don't need to install. I mention it here because many tutorials mention installing libssl, if you install will encounter an error.

Check your SSL:

dpkg -l | grep libssl3

2.1 Import the MongoDB GPG Key

#update
sudo apt update 
#install curl
sudo apt install gnupg curl -y 
#use curl to download MongoDB
curl -fsSL https://www.mongodb.org/static/pgp/server-8.0.asc | \ sudo gpg -o /usr/share/keyrings/mongodb-server-8.0.gpg \ --dearmor

2.2 Add the MongoDB Repository

echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-8.0.gpg ] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/8.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-8.0.list

sudo apt update

2.3 Install MongoDB

sudo apt install -y mongodb-org

2.4 Start and Enable the MongoDB Service

sudo systemctl start mongod 
sudo systemctl enable mongod 
sudo systemctl status mongod

3. Install GenieACS

You can refer genieacs official site for more details

sudo apt update
sudo apt install nodejs npm

sudo npm install -g genieacs@1.2.13
sudo useradd --system --no-create-home --user-group genieacs

mkdir /opt/genieacs
mkdir /opt/genieacs/ext
chown genieacs:genieacs /opt/genieacs/ext

4. genieacs setting

4.1 modify `genieacs.env`

vi /opt/genieacs/genieacs.env

GENIEACS_CWMP_ACCESS_LOG_FILE=/var/log/genieacs/genieacs-cwmp-access.log
GENIEACS_NBI_ACCESS_LOG_FILE=/var/log/genieacs/genieacs-nbi-access.log
GENIEACS_FS_ACCESS_LOG_FILE=/var/log/genieacs/genieacs-fs-access.log
GENIEACS_UI_ACCESS_LOG_FILE=/var/log/genieacs/genieacs-ui-access.log
GENIEACS_DEBUG_FILE=/var/log/genieacs/genieacs-debug.yaml
NODE_OPTIONS=--enable-source-maps
GENIEACS_EXT_DIR=/opt/genieacs/ext

4.2 Set file ownership and permissions

sudo chown genieacs:genieacs /opt/genieacs/genieacs.env
sudo chmod 600 /opt/genieacs/genieacs.env

4.3 adding jwt secret

node -e "console.log(\"GENIEACS_UI_JWT_SECRET=\" + require('crypto').randomBytes(128).toString('hex'))" >> /opt/genieacs/genieacs.env

If you don't add this one will occur error when accessing genieacs url like below:

4.4 Create logs directory

mkdir /var/log/genieacs
chown genieacs:genieacs /var/log/genieacs

4.5 Create systemd unit files

4.5.1 Run the following command to create genieacs-cwmp service

you can use the which genieacs-cwmp to check the location and paste in below ExecStart option.

sudo systemctl edit --force --full genieacs-cwmp

[Unit]
Description=GenieACS CWMP
After=network.target

[Service]
User=genieacs
EnvironmentFile=/opt/genieacs/genieacs.env
ExecStart=/usr/bin/genieacs-cwmp

[Install]
WantedBy=default.target

4.5.2 Create genieacs-nbi service

you can use the which genieacs-nbi to check the location and paste in below ExecStart option.

sudo systemctl edit --force --full genieacs-nbi

[Unit]
Description=GenieACS NBI
After=network.target

[Service]
User=genieacs
EnvironmentFile=/opt/genieacs/genieacs.env
ExecStart=/usr/bin/genieacs-nbi
ExecStart=/usr/local/bin/genieacs-nbi

[Install]
WantedBy=default.target

4.5.3 Create genieacs-fs service
you can use the which genieacs-fs to check the location and paste in below ExecStart option.

sudo systemctl edit --force --full genieacs-fs

[Unit]
Description=GenieACS FS
After=network.target

[Service]
User=genieacs
EnvironmentFile=/opt/genieacs/genieacs.env
ExecStart =/usr/local/bin/genieacs-fs

[Install]
WantedBy=default.target

4.5.4 Create genieacs-ui service:

you can use the which genieacs-ui to check the location and paste ExecStart

sudo systemctl edit --force --full genieacs-ui

[Unit]
Description=GenieACS UI
After=network.target

[Service]
User=genieacs
EnvironmentFile=/opt/genieacs/genieacs.env
ExecStart=/usr/local/bin/genieacs-ui 

[Install]
WantedBy=default.target

4.5.5 configure log file rotation using logrotate

nano /etc/logrotate.d/genieacs

/var/log/genieacs/*.log /var/log/genieacs/*.yaml {
    daily
    rotate 30
    compress
    delaycompress
    dateext
}

4.5.6 Enable and start services

sudo systemctl enable genieacs-cwmp
sudo systemctl start genieacs-cwmp
sudo systemctl status genieacs-cwmp

sudo systemctl enable genieacs-nbi
sudo systemctl start genieacs-nbi
sudo systemctl status genieacs-nbi

sudo systemctl enable genieacs-fs
sudo systemctl start genieacs-fs
sudo systemctl status genieacs-fs

sudo systemctl enable genieacs-ui
sudo systemctl start genieacs-ui
sudo systemctl status genieacs-ui

It should be running all 4 services.

4.5.7 access to the geniacs http://IPaddress:3000

You can use this command to check host or IP: hostname -I or ip a

If you want your cpe to connect to genieacs your url must add port 7547

http://genieIPADD:7547

It should work now, and look like below

Summary

It should have a great understand on how to setup geniacs server, an easy way. I have been encouter many issue especially with libssl and mogobdb on differeent Ubuntu version. I literally have figure out what causes the problem, the version not support.

Lastly thanks for reading my post, any question please free to leave comment.

NGINX HTTP Server

chenchih — Tue, 05 Aug 2025 03:21:45 +0000

Let me show you how to setup HTTP the most easy way using NGINX. I used to setup HTTP with Apache or other related tool, but it seem like NGINX is much easier.

NGINX HTTP Server

Below are the basic configure version:

OS: ubuntu 20.04

Step 1. Install Nginx:

sudo apt install nginx -y

Step2 Verify Nginx is Running show statusd

sudo systemctl status nginx

3.Adjust Firewall (UFW - if active):

sudo ufw allow 'Nginx HTTP'
sudo ufw reload

4. Test Nginx from your browser (Optional but Recommended):

please navigate your web browser using your local IP it should occur index page

http://172.21.201.250
or 
http://127.0.0.1

Step 5. set permission

sudo chmod 644 /var/www/html/

Step 6. Edit ngix configure to allow index to show like file management

sudo nano /etc/nginx/sites-available/default
    location / {
        try_files $uri $uri/ =404;
        autoindex on; # <--- Add this line
    }

Step 7. Test Nginx configuration for syntax errors:

when you change your configure you can verify whether it will occur error or not.

sudo nginx -t

Step 8. Reload Nginx to apply changes

sudo systemctl reload nginx

Step 9. Change your index into file management

Default will have index.nginx-debian.html in /var/www/html directory. Make sure there's no .html file in directory, it will treat any html file as index. I will rename html file ext into bk. You no need to delete it, maybe in future you want to use again.

sudo mv /var/www/html/index.nginx-debian.html /var/www/html/index.nginx-debian.html.bak

Step 10. Access to your site will show like File Management, display all your files or folder.

Oh My Posh- Powershell Terminal Setup

chenchih — Mon, 17 Jun 2024 03:38:22 +0000

I would like to share how to set up a fancy and productive terminal prompt under Windows PowerShell. Many people who have ever used Linux or Mac, will notice some great command, whereas the window command is not useful. Today I would like to show a tutorial on how to set up oh-my-posh environment.

If you ever use Linux/mac probably have heard of oh-my-zsh, it also makes our prompt to be more fancy. In oh-my-zsh it only supports zsh shell, but oh-my-posh supports many shells, but most people use it under the window. Both of these frameworks are used not just to fancy our terminal but also to let us be more productive when using cli command. Cli command means you can use the command to achieve many stuff without using the UI interface, which includes copy, filter, delete, rename, and many more.

1. Install Window Terminal and PowerShell

Before setting up oh-my-posh you need to install the window terminal and Powershell first. The default window provides you powershell which it's version 5.x version. You will need to install Powershell 7.x version which is typically named PowerShell core.

Powershell core supports many more functions in plugins, if not used it might occur error when installing and importing plugins. Window Terminal allows our prompt to display properly with the nerd font or fancy logo.

Window Terminal

There are two methods:

Store: access Microsoft and type Window Terminal
Winget:

winget install Microsoft.WindowsTerminal

There are two methods:

Powershell

Store: access Microsoft and type Power Shell
Winget:

winget install Microsoft.Powershell

Window package installation

Winget

In case your winget is not able to use it, please download and install it under this link:

Step 1: Download under this link
Please use either link ok:
https://learn.microsoft.com/en-us/windows/package-manager/winget/
https://github.com/microsoft/winget-cli/releases
The file will look like Microsoft.DesktopAppInstaller_8wekyb3d8bbwe.msixbundle

Step2: Install by command

Add -AppPackage

If you ever meet Fail-Error Execution Policies, probably it might be the policy problem, please change it to remote

check the current policy: Get-ExecutionPolicy -List

        Scope ExecutionPolicy
        ----- ---------------
MachinePolicy       Undefined
   UserPolicy       Undefined
      Process       Undefined
  CurrentUser       Undefined
 LocalMachine    RemoteSigned

set policy: Set-ExecutionPolicy RemoteSigned

For more detail on each policy, please refer here

Restricted (Default): No scripts are allowed to run, not even ones you write yourself.
RemoteSigned: This allows scripts signed by a trusted source (like Microsoft) to run. It's like having a guard who checks IDs – only scripts with valid "signatures" (like an artist's signature) are allowed. Scripts you write yourself wouldn't work unless you sign them with a special certificate. Files that are downloaded from the internet must be signed by a trusted publisher or must be unblocked
AllSigned: This allows any script with a valid signature to run, regardless of who signed it. It's less secure than RemoteSigned because it trusts any "signature," even from unknown sources. Imagine a guard who just checks for a valid ID but doesn't care who issued it. Scripts must be signed by a trusted publisher, like Microsoft or a well-known software vendor. Think of it like a document requiring a verified signature from a recognized authority.
Bypass (Not Recommended): This completely disables script execution restrictions. It's like having no security guard at all! Any script can run, which is very risky and not recommended unless you fully understand the potential dangers.

2. Oh-My-Posh setup

Step1: install Nerd Font

Please download either of the link below to download and install nerd font:

Download:
- https://github.com/ryanoasis/nerd-fonts
- https://www.nerdfonts.com/font-downloads
Install:

Extract the file and right-click to install or drag into C:\Windows\Fonts

Step2: Window terminal setting

Navigate window terminal and set below setting:

Startup: Default set PowerShell, Deafualt terminal: window terminal.
Setting like below picture:
Appearance
Access to powershell>appearance> change fontface to nerd font

Step3: install oh-my-posh

Install Oh-my-posh

winget install JanDeDobbeleer.OhMyPosh -s winget

update the latest version

winget upgrade JanDeDobbeleer.OhMyPosh -s winget

After installing it press Oh-my-posh on the terminal to check command works or not.

Step4: activate theme

activate default theme

oh-my-posh init pwsh | invoke-expression

list all the theme look like:

Get-PoshThemes

or display all theme location and filename

Get-PoshThemes –List

Change theme according to above theme filename

oh-my-posh init pwsh --config "$env:POSH_THEMES_PATH\iterm2.omp.json" | Invoke-Expression

Step5: prompt setting writing profile

We need to create profile to write the theme in it. in Step4 it will only take effect on that session temporary, when reopening new session the command you enter like theme will be lost remain default.

profile location of different poweshell:

PS5.1: C:\Users\test\Documents\WindowsPowerShell

PS7.1: C:\Users\test\Documents\PowerShell

generate a file: will only generate an empty file

New-Item -Path $PROFILE -Type File –Force

You need to modify the file using notepad $profile, you can change Notepad to any you prefer text editor. The $profile will automatically open the file it generates, which no need to type the full path of the profile location.

Add your previous command on changing the theme to your profile

oh-my-posh init pwsh --config "$env:POSH_THEMES_PATH\iterm2.omp.json" | Invoke-Expression

You can also assign the full path of the theme below i mention many examples of assigned themes:

#full path
$themepath = 'C:\Users\test\Documents\PowerShell\shanselman_v3-v2.json'
oh-my-posh --init --shell pwsh --config $themepath | Invoke-Expression

# URL 
oh-my-posh init pwsh --config 'https://raw.githubusercontent.com/JanDeDobbeleer/oh-my-posh/main/themes/jandedobbeleer.omp.json' | Invoke-Expression

# same location as $profile 
$omp_config = Join-Path $PSScriptRoot ".\theme.json"
oh-my-posh --init --shell pwsh --config $omp_config | Invoke-Expression

You might wonder how the $env knows the full path of the default theme, it's because it's an environment variable in powershell, you can use this command to check the env variable and path.

ChildItem env:

Note: You can set and remove an $env variable using the below command. But this will only take effect if you write into $profile, or in the command(temporary). If you set the env but not add into $profile will not take effect.

#set $env
Set-Item -Path env:MYCUSTOMVAR –Value <path location>

#remove
$env:<name> = $null

Step6 add some function or alias to profile

Now we can assign some Linux commands to alias, which you can use Linux commands on PowerShell. You will be using a lot of the $profile in the plugin, just think it's a configuration of PowerShell.

Before setting the alias or functions, let's install git and node, it's optional but if you want to add git to the alias, it is highly recommended you install it here.

Install git

 winget install --id Git.Git -e --source winget

Install nodejs

 WINGET INSTALL OPENJS.NODEJS.ltS

Alias

Set-alias tt tree
Set -Alias ll ls
Set-Alias g git
#Set alias vim nvim
Set-Alias grep findstr
Set-Alias tig 'C:\Program Files\Git\usr\bin\tig.exe'
Set-Alias less 'C:\Program Files\Git\usr\bin\less.exe' 

# Ultilities (Optional)
function which ($command) {
    Get-Command -Name $command -ErrorAction SilentlyContinue |
        Select-Object -ExpandProperty Path -ErrorAction SilentlyContinue
}

Function

adding function can be alternative of alias

function getenv{
Get-ChildItem env: 
}

function head {
  param($Path, $n = 10)
  Get-Content $Path -Head $n
}

function tail {
  param($Path, $n = 10)
  Get-Content $Path -Tail $n
}

function grep($regex, $dir) {
    if ( $dir ) {
        Get-ChildItem $dir | select-string $regex
        return
    }
    $input | select-string $regex
}

function df {
    get-volume
}
#get $env variable
function getenv {ChildItem env:}

# Git Shortcuts
function gs { git status }
function ga { git add . }
function gc { param($m) git commit -m "$m" }
function gp { git push }
function g { z Github }
function gcom {
    git add .
    git commit -m "$args"
}
function lazyg {
    git add .
    git commit -m "$args"
    git push
}

# adding hosts shortcut 
function hosts { notepad c:\windows\system32\drivers\etc\hosts }

If you are interested in the profile, please refer to my profile on this link.

3. Plugin

There are many more plugins, but I will choose only those I think are commonly used by people or developers.

Terminal Icons

Display icon according to file type

install module

Install-Module -Name Terminal-Icons -Repository PSGallery -Force

import module

Import-Module Terminal-Icons

What will it look like, please refer below picture.

psreadline(Autocompletion)

This is a powerful module, which has many functions on it. I will not use all of them, I will only pick important ones or useful ones. If you’re interested you can study on the official site. PSReadline basely is developed by Microsoft and used under PowerShell.

You can use this command to get the default hotkey: Get-PSReadLineKeyHandler

install module

Install-Module PSREadLine -Force
#or below more detail which recommends 
Install-Module -Name PSReadLine -AllowPrerelease -Scope CurrentUser -Force -SkipPublisherCheck

Import module

#method1
Import-Module PSReadLine
#method2
if ($host.Name -eq 'ConsoleHost')
{
    Import-Module PSReadLine
}

all psreadline plugin

Set-PSReadLineOption -EditMode Windows
Set-PSReadLineOption -PredictionSource History
Set-PSReadLineOption -PredictionViewStyle ListView
Set-PSReadLineKeyHandler -key Tab -Function Complete
Set-PSReadLineKeyHandler -Key Tab -Function MenuComplete
Set-PSReadlineKeyHandler -Chord ctrl+x -Function ViExit
Set-PSReadLineKeyHandler -Chord 'Ctrl+d' -Function DeleteChar   
Set-PSReadlineKeyHandler -Chord ctrl+w -Function BackwardDeleteWord
Set-PSReadlineKeyHandler -Chord ctrl+e -Function EndOfLine
Set-PSReadlineKeyHandler -Chord ctrl+a -Function BeginningOfLine
Set-PSReadLineKeyHandler -Key Alt+B -Function SelectShellBackwardWord
Set-PSReadLineKeyHandler -Key Alt+F -Function SelectShellForwardWord

# CaptureScreen is good for blog posts or emails showing a transaction
# of what you did when asking for help or demonstrating a technique.
#ctrl+c and ctrl+d  to copy terminal 
#ctrl+v to paste
Set-PSReadLineKeyHandler -Chord 'Ctrl+d,Ctrl+c' -Function CaptureScreen

if you feel like the color is too light can't read it might be the color, so you can add the color like below:

Set-PSReadLineOption -Colors @{
    Command = 'Yellow'
    Parameter = 'Green'
    String = 'DarkCyan'
}

Zoxide(directory jumper)

This lets you navigate the file system based on your cd command history, which just renumber your last command’s directory.

Install-Module -Name Z –Force

So imagine every time go to a specific location like cd C:\Users\User\Downloads
But if we visit the directory once, it will remember it, so next time you can just type z with the directory or file name, like z Download, it will access to cd C:\Users\User\Downloads. It will recognize the path already.

PSFzf(Fuzzy finder)

This is a tool like an interactive search bar on your terminal command line that allows regex matching, and filtering files, or directories.

iNSTALL SCOOP (if you have scoop installed skip this part)

irm get.scoop.sh | iex

Install fzf an pszf

scoop install fzf #install fzf
Install-Module -Name PSFzf -Scope CurrentUser -Force #powershell

Import module into the profile

Import-Module PSFzf
# Override PSReadLine's history search
Set-PsFzfOption -PSReadlineChordProvider 'Ctrl+f' -PSReadlineChordReverseHistory 'Ctrl+r'

Below is how to use fzf to search your file or history command:

Ctrl+r(Fzf Reverse Fuzzy Search)：to fuzzily search your command searches your history, similar to the history command, and run select or use it
Alt+c (Fzf Set Location): fuzzily search for a directory in your home directory and allow to cd to the directory. Basely this is quickly selected to subdirectory.
CTRL-f (Fzf Provider Select): to fuzzily search for a file or directory in your home directory and select it will get the path of it

Note: In psreadline if you use the Set-PSReadLineOption -EditMode Emacs then probably alt+c you will not be able to use, due to the hotkey is been conflict, which psreadline will take higher priority. in the below picture you can see alt+c is a conflict, so if you use alt+c it will be a capitalized word in this case.

If I try to change the conflict function capitalize word using this Set-PSReadLineKeyHandler -Chord 'Alt+Shift+C' -Function CapitalizeWord it still won't change, probably it's been hotcode.
So there are two solutions to fix it:

Method1: don't use emac, change to window or vi mode
method2: use the alternative command as a function to use it

function FzfNav { Get-ChildItem . -Recurse -Attributes Directory | Invoke-Fzf | Set-Location }

layout fzf

Layout allows you to adjust the percentage of the navigator bar, and adjust the total result position, like below. You can add it to the function when next time you want to use just call a function instead of typing a complicated command.

$(fzf --height 40% --reverse)

preview files in fzf

This allows you to preview or read the file without opening the file to see whether this is the file you want. You can also add text editor in front when you enter the file allowing you to modify it.

install

scoop install bat

preview file

fzf --preview='cat {}'

Preview and enter the file to modify on a specific text editor

function ff{
vim $(fzf --preview 'bat --style=numbers --color=always --line-range :500 {}')
}

search syntax

You can use this related syntax to search your file

'wild: include wild
!^music: do not start with music
!.mp3$: do not end with .mp3
!test: do not include test
^music: start with music .mp3$ : end with .mp3

FastFetch

Fastfetch is an alternative to neofetch tool that will show your system information. You can find more information on think fastfetch link. This awesome-fetch provides many alternative related tools.

#generate config:
fastfetch --gen-config
#location window: C:\Users\test\.config\fastfetch\config.jsonc
#load customer cfg: 
fastfetch --load-config /path/to/config_file
fastfetch --load-config .\aa.jsonc

#SHOW ONLY HARDWARE: 
fastfetch -c hardware

#PRINT LOGOS: 
fastfetch --print-logos

#USE LOGO: 
fastfetch --logo sparky

#print all logo: 
fastfetch --print-logos

#USE CERTAIN COLOR : 
fastfetch --color blue

YOu can find many more preset examples here to see more settings.

window terminal some setting

1. Automatic copy string when select it

Method1: adding into the window terminal
Open terminal setting shortcut: ctrl+shift+p, or ctrl+shift+, to open settings.json file
Select will copy: copyonselect=true

Method2: add into profile
You can also automatically add to the profile:

function cpy { Set-Clipboard $args[0] }
function pst { Get-Clipboard }

2. Paste multiply line pop warming

If you copy multiple lines and paste them into the window terminal will pop warming, to disable the warming we can set Multipastingwarming=false

This is what I mean about copy and pasting multiple line warming:

3. Clear-Hidden showing the terminal logo

Powershell core release new version 7.4.2 will pop, you can hide this message or logo, just add -nologo into the window terminal like below

conclusion

In this post I just wish to keep it simple on how to set up oh-my-posh, however, there are many more to cover. I have another post of Medium which cover a lot of detail. I wish to make it short in this post, there are many of the psreadline I didn't make more detail on each function.
