bash script problem

Hi all,

I'm observing a problem which makes my script stop to run. the problem is when I copy the script into a new machine (ubuntu-server), and try to run the script the kernel stops it from running and throw an error.
I don' really know what the problem is; but when i write the script in that machine using vi editor, the script runs properly...

any idea about the problem?

Let us know the exact error.

let us know the if the copied file has executable permission

also check it using

ls -ld scriptname.sh

What's the error message you get?
Hard to guess without that... Maybe hidden character?

what's the error? did you check the file permission of the script after you have transferred it on a different machine e.g.(ubuntu-server)?

the script does not have .sh extention at the end exactly! but, yes I gave the owner suffice permissions to execute.

It may sound silly, but since v. 6.10 the default shell after installation is dash, not bash, and it caused some problems to my scripts when they were not explicitely evoked with bash.
Judging from the title of this post you prepared the script for bash, maybe your other machine has dash as default shell?

actually, every shell script should specify it's desired run shell
in the first line, as in

Code:

#!/bin/bash
echo "this is to be ran in bash, not dash, not tcsch, or anything"
