The main problem is the script has the wrong name of when the filename should be prargs. The second problem is there should be a β€œshebang” at the top telling the system it is a bash script:


while [ "$#" -ne 0 ]  
    echo "$Count: $1"  

Note: Your script was missing the 1: , 2: , etc. parameter count. I’ve added that missing pieces with:

echo "$Count: $1"

So when you run the script you now see:

$ prargs a 'b c' d
1: a
2: b c
3: d

The next problem is calling the prargs without specifying a location in front. If you place your script in one of your paths it will be found without specifying a directory. To see your current paths use: echo $PATH. Many people will create a path in their home directory for personal scripts:

mkdir -p $HOME/bin

After this reopen the terminal to have it in your path. So create your script as $HOME/bin/prargs and then mark it executable:

chmod a+x $HOME/bin/prargs

After this no matter what your current directory is you can type prargs a 'b c' d.
