Bash Hate, Zsh Love

January 14, 2011

…Or why shell scripting is not really programming. Two scripts, one called bash-hate:

#!/bin/bash
count=0
cat /dev/null -  | while read line; do
    ((count++))
done
echo $count

and the other one zsh-love:

#!/bin/zsh
count=0
cat /dev/null -  | while read line; do
    ((count++))
done
echo $count

Then:

% cat testfile | ./bash-hate
0

% cat testfile | ./zsh-love
9

(Yes, I know about subshells. Just learn a real programming language.)
