Bash: Embed functions in commands.

Sometimes you want to do a complex action with your shell script but you don't want the mess of creating another shell file to call externally.

You can export the function and use it much like a call back.

#!/bin/bash

function Stats {    
    FILE="$@"
    STAT=$(stat --format="%s" "$FILE")
    echo "File $FILE is $STAT bytes"
}
export -f Stats
find . -type f -exec bash -c 'Stats "{}"' \;
