Shell Programming and Scripting

and I have to chmod ugo+x the file then I can execute it like ./script right?


I cant understand why it wont work.

This kind of thing can happen when you create/edit a file on MS Windows and ftp the file over to UNIX with out eliminating the ^M (carriage return) characters.

Try this:

Code:

ex - yourscript.sh
1,$s/^M//
wq

You enter the ^M by hitting Control-V and then Control-M.

You can confirm that these characters exist in your file by dumping the file through od.

Code:

od -x yourscript.sh

The last line of the output will have 0d0a values if you need to strip the carriage returns.

Yeah, that should work. Don't know what to tell you.

Just an idea - make sure your /bin/bash is executable and NOT some kind of the 'script' itself.

Thank you so much, this worked. Once again, thank you very much, I couldnt of done it without yours guys help.

To debug your script, the shell has a useful feature, it is:set -xv. You can place this entry anywhere in the script to provide useful debug information when you run the script. I usually comment out the line after a debug-cycle, but you can change the -xv to a +xv to accomplish the same behavior.

Good luck!
