bash foo

Instead of writing tons and tons of small scripts < 10 lines that all depend on each other I have the habbit of writing them as functions and throwing them into one file (easier to edit, less worries about them depending on each other). To be able to use the functions from the bash shell, just add $(basename $0) “$@” to the END of the file, and add symlinks function_name -> file.

Example:
$ ln -s foo.sh foobar

$ cat foo.sh

#!/bin/bash
foobar() {
echo "world domination"
return
}

$(basename $0) "$@"

#!/bin/bash

foobar() {

echo "world domination"

return

}

$(basename $0) "$@"
