I have switched to zsh, how can I run a script which is written for bash?

I don't want to modify the script to put #!/bin/bash in the beginning for the script since it is version controlled.

Is there another way?

The line of the script having problem is:

for f in `/bin/ls v/*/s.sh v/*/*/v.sh d/*/*/v.sh 2> /dev/null`

This line is terrible! It's terrible bash practice to parse the output of ls. – gniourf_gniourf Dec 21 '12 at 20:56
    
I agree with @gniourf_gniourf. While it's a bit outside the scope of this question, you would be better off doing this: for f in v/*/s.sh v/*/*/v.sh d/*/*/v.sh (this uses the built in glob-substitution of bash) – neersighted Dec 21 '12 at 23:08

You can run the script with bash manually:

bash myscript.sh

A better and more permanent solution (that should have been there in the first place) is to add a shabang line:

#!/usr/bin/env bash

Once that line is added, you can run it directly, even in ZShell:

% ./myscript.sh

As far as version control goes, you should commit this line, for the good of all the developers involved.

Agreed -- a script that requires bash, but doesn't start with a bash shebang, should be considered broken. And broken scripts should be fixed. (Though as @gniourf_gniourf pointed out, that's not the only problem here.) – Gordon Davisson Dec 21 '12 at 22:38
    
As long as we are on the subject of shebangs: Why not correct to #!/usr/bin/env bash. That way the scripts work on more systems. (/usr/local/bin/bash, /usr/bin/bash etc are all hardcoded and you need to fix each script for each shell you use. With env you only have to maintain one single program). – Hennes Dec 22 '12 at 7:05
