Question

I have a library file in which I have one alias:

$ cat mylib.sh
alias mal='ls -l'

$cat test.sh
#!/bin/bash
source mylib.sh
mal

$./test.sh
./test.sh: line 3: mal: command not found

Any thoughts?

Answer 1

To execute an alias in a non-interactive shell, use

shopt -s expand_aliases

You might instead want to use functions:

mal() { 
    ls -l
}

mal
