Sudden permission problem in Ubuntu

cdworkcd — Thu, 28 Jul 2022 06:08:00 +0000

Hi,
I have Ubunto on Win 10.
(It's connect with wsl)
always- everything woeked well.
this morning I opened the Terminal and typed in the root mkdir some
and got: mkdir: cannot create directory ‘some’: Permission denied.

and when I did ls I got only folders and files of installations whithout the folders and the files I created.

If anyone knows what the problem is- Itll help me a lot
thanks

unpack tar doesn't work for me in the script but it does in Terminal

If possible I have a question:
this what I did in the Terminal:

$ tar cvf compress.tar jenkinsfile
jenkinsfile
$ ls
compress.tar  jenkinsfile
$ rm jenkinsfile
$ ls
compress.tar
$ tar --overwrite -xvf compress.tar
jenkinsfile
$ ls
compress.tar  jenkinsfile
$

It works fine- the file jenkinsfile unpacked. and this is my script: ("$1" = compress.tar in this case)

...
function func_decompress(){
    check=0
    case $1 in
    *.tar.gz | *.tar | *.tar.bz2)
        check=1
        tar --overwrite -xvf "$1" 
        rm "$1" ;;
    *.zip)
        check=1
        unzip -o "$1"
        rm "$1" ;;
    *.bz2)
        check=1
        bunzip2 "$1" ;;
    *.gz)
        check=1
        gunzip "$1" ;;
    esac
    if [ $check == 0 ]
    then
        uncompressPrintFunc "$1"
    else
        compressPrintFunc "$1"
    fi
}
...

I would appreciate it if someone could help me! Thanks
