What is termux?
For those who do not know what termux is:
Termux is an Android terminal emulator and Linux environment app that works directly with no rooting or setup required. A minimal base system is installed automatically - additional packages are available using the APT package manager.
Basic shortcuts
Volume Down --> Ctrl
Volume Up --> Esc
So to clean your screen you can press Volume Down + l which is the same as if you were in a normal Linux terminal
To exit your terminal you can press Volume Down + d
More advanced keyboard settings (terminal) visit this link on termux wiki.
Use F-droid instead of google play store
The updated termux version can only be found on the F-droid repo, read more here
In my case I had difficulties downloading F-droid directly to my android, so I downloaded it on my computer and started a http server using python to download it directly in my phone:
aria2c -c https://f-droid.org/F-Droid.apk
python3 -m http.server
I had to get my local ip (computer) and type it on my firefox on the phone:
http://ip:8000
There is also another alternative store: https://auroraoss.com/
Environment variables
Termux has a $PREFIX environment variable:
/data/data/com.termux/files/usr
You can use it in some cases to avoid typing all the above path
Initial install:
First install from F-droid:
termux termux-api
Backing up termux settings
source: https://wiki.termux.com/wiki/Backing_up_Termux
In this example, a backup of both home and sysroot will be shown. The resulting archive will be stored on your shared storage (/sdcard) and compressed with gzip.
- Ensure that storage permission is granted:
termux-setup-storage
NOTE: Every time you have any permissions problem revoke termux permissions and run termux-setup-storare
- Backing up files:
tar -zcf /sdcard/termux-backup.tar.gz -C /data/data/com.termux/files ./home ./usr
Backup should be finished without any error. There shouldn't be any permission denials unless the user abused root permissions. If you got some warnings about socket files, ignore them.
Restoring
Here will be assumed that you have backed up both home and usr directory into same archive. Please note that all files would be overwritten during the process.
- Ensure that storage permission is granted:
termux-setup-storage
- Extract home and usr with overwriting everything. Pass --recursive-unlink to remove any junk and orphaned files. Pass --preserve-permissions to set file permissions as in archive, ignoring the umask value. By combining these extra options you will get installation state exactly as was in archive.
tar -zxf /sdcard/termux-backup.tar.gz -C /data/data/com.termux/files --recursive-unlink --preserve-permissions
Now close Termux with the "exit" button from notification and open it again.
Backup using termux-backup:
In my case I have used this command
termux-backup ~/storage/shared/Documents/termux-backup.tar.xz
To restore just change "backup" for "restore"
Fix: repository is under maintenance or down
This solution comes from this youtube video/channel
The error is as follows:
N: Metadata integrity can't be verified, repository is disabled now.
N: Possible cause: repository is under maintenance or down (wrong sources.list URL?).
This issue is caused by bad repo sources or mirrors and because of this the package installations fail with an error saying "repository is under maintenance or down".
A solution for this issue is to change the mirrors using the termux-change-repo command and that is what this video explains.
So, the commands are:
termux-change-repo
Use space to select all the above options until you reach the next screen as follows:
In my case I chose the second of the list that follows
Install some useful apps
pkg update && pkg upgrade
pkg install termux-tools openssh mpv wget termux-api neovim python iproute2 git
TIP: You can abbreviate "install" just typing "in"
Copy your public ssh key to your computer
Generate your ssh-key on your android:
ssh-keygen -b 4096 -t rsa
ssh-copy-id -i ~/.ssh/id_rsa.pub user@ip
TIP: When generating your ssh keys do not type any password and set your sshd to allow only public key logins, this way you can login easily.
You also need to set a password to your use, just in case you need to access your ssh server without your keys:
passwd
Discover your termux "user" name:
whoami
--> this is mine: u0_a225
You can also get your user name by typing:
echo $USER
Start your sshd:
sshd -p 2222
Copy your computer's ssh public key to your android (termux):
ssh-copy-id -p 2222 -i ~/.ssh/id_rsa.pub u_0a225@yourip
Using scp
scp -P 2223 aliases u0_a103@192.168.15.30:~/storage/downloads
scp -P 8022 *.mp3 u0_184@192.168.15.2:~/storage/music
Access your termux using nautilus
Remember to change the port number accordingly!
sftp://u0_a225@phone/data/data/com.termux/files/home
sftp://u0_a225@192.168.0.100:8022/data/data/com.termux/files/home
Some useful aliases (~/.bashrc)
alias localip='ip addr | grep -Po '\''(?<=inet)\s(?!127)[^/]+'\'
alias vim='/data/data/com.termux/files/usr/bin/nvim'
Set folders
According to termux wiki: In order to have access to shared storage (/sdcard or /storage/emulated/0), Termux needs a storage access permission. It is not granted by default and is not requested on application startup since it is not necessary for normal application functioning.
Storage access permission will not enable write access to the external sdcard and drives connected over USB.
termux-setup-storage
termux style
Having a nice looking terminal for me is something essential, so:
git clone https://github.com/adi1090x/termux-style
cd termux-style
ls
chmod +x install
./install
termux-style
How to use Termux to download YouTube videos
wget -c https://pastebin.com/raw/RijZvset -O install.sh
dos2unix install
chmod u+x install.sh
./install.sh
Setup your python libs in a more sane way:
pip3 install pipx
pipx ensurepath # make sure to set path
pipx install yt-dlp # fix some youtube-dl issues [official site](https://github.com/yt-dlp/yt-dlp)
pipx install yturl
Then you can:
alias youtube-dl="/data/data/com.termux/files/home/.local/bin/yt-dlp"
The instalation script:
#!/data/data/com.termux/files/usr/bin/bash
# 4/05/2017 Gabi Tiplea
echo -e "Updating default packages\n"
apt update && apt -y upgrade
echo -e "Requesting acces to storage\n"
termux-setup-storage
sleep 5
echo -e "Installing python\n"
packages install -y python
echo -e "Installing youtube-dl\n"
yes | pip install youtube-dl
echo -e "Creating the Youtube folder to download the files\n"
mkdir ~/storage/shared/Youtube
echo -e "Creating youtube-dl folder for config\n"
mkdir -p ~/.config/youtube-dl
echo -e "Creating bin folder\n"
mkdir ~/bin
echo -e "Downloading and installing termux-url-opener\n"
wget http://pastebin.com/raw/LhDxGbtY -O ~/bin/termux-url-opener
dos2unix ~/bin/termux-url-opener
echo -e "\n"
echo -e "Copyright 2017 Gabi Tiplea\n"
Install trash-cli
pipx install trash-cli
alias rm='echo use trash instead!'
Trash-cli moves your files to ~/.local/share/Trash
Set youtube-dl script permissions
Fasd_cd
Fasd (pronounced similar to "fast") is a command-line productivity booster. Fasd offers quick access to files and directories for POSIX shells. It is inspired by tools like autojump, z and v. Fasd keeps track of files and directories you have accessed, so that you can quickly reference them in the command line.
The name fasd comes from the default suggested aliases f(files), a(files/directories), s(show/search/select), d(directories).
Fasd ranks files and directories by "frecency," that is, by both "frequency" and "recency." The term "frecency" was first coined by Mozilla and used in Firefox (link).
