What Others Think

Find supports multiple paths already. You can omit the for loop so it's just: find /first/path /second/path /file.txt -type f -exec cat {} \; | wc -l

Ok, modified, thx :)

I would recommend changing cat {} \; to cat {} + Putting in the + uses only one cat command (or the minimum number possible) Also, change $* to "$@" so that if any of the arguments have spaces, bash doesn't turn them into multiple arguments. So, altogether, it becomes: count() { find "$@" -type f -exec cat {} + | wc -l; }
