shell script tha tdoes not work

Tonatiuh — Sun, 04 Jun 2006 20:24:43 GMT

Red Hat Enterprise linux 4.0

This is MyScript.sh

#!/bin/bash
groupadd oinstall

But it returns an erro when I run it as root.

[root@lab2 ~]# ./MyScript.sh
: bad interpreter: No such file or directory

I do have the file /bin/bash

[root@lab2 ~]# ll /bin/bash
-rwxr-xr-x 1 root root 616312 Dec 6 2004 /bin/bash

Any idea?

Hello,

Almost positively =your problem is related
to bad End-Of-Line (EOL).

My guess, is it possible that you copied
this script via FTP in ASCII mode, or
got it from a Windows system? Type this:

sed 1q MyScript.sh | od -c

If there's a trailing Carriage Return
(^M, \015, or \r\n) character after the
/bin/bash on that line, then you have a DOS-formatted script.

It would produce this behaviour because
you are trying to run "/bin/bash^M",
not "/bin/bash".

Simple fix:

dos2unix MyScript.sh
