#!/bin/sh not honored
 

We have recently installed a Redhat Linux. My account defaults to tcsh shell. When I tried to run a script that have the first line as #!/bin/sh, I got "command not found". So I have to run the script using /bin/sh scriptFile. Is there anything configuration I can do to get rid of this headache? Thanks.

The usual approach is to put a link in /bin to tcsh or whatever

ls -l /bin/sh
lrwxrwxrwx 1 root root 4 2005-07-03 03:40 /bin/sh -> bash

To make such a link execute this command as root:

ln -s /bin/tcsh /bin/sh

/bin/sh is normally a link to Bash, not to tcsh. If you make a link from /bin/tcsh to /bin/sh you will likely get problems, since applications expecting bash will not work with tcsh.

Or is it just an path environment problem. What happens when you use the command
./scriptfile

Make sure scriptfile permissions are set for executable.

Unlike windows linux only searches for a file using the users path.

Have you made the script executable by doing:
Now you can run it with ./ScriptFile

If not, your script have to be run by by executing

It turned out that the file is in Windows text format. My vi does not show those ^M's. After removing those, it worked fine. Thanks.

Check out dos2unix for removing the ^M's. Also, unix2dos for putting them back :)

I hope this helps

What chance it was un-zipped in windows and copied over ???. Simple sed will fix the crlf issue.
