simple shell file


Hi -

I'm completely new to writing the shell files to run in batch.
It seemed to be completely straight forward, and I wrote the following file: simpTask.sh

#!/bin/bash
echo 'hello world'


then saved it, then made it an executable

chmod a+rx simpTask.sh

then tried to run it

./simpTask.sh

and got the following message

"cannot execute binary file"

any help would be greatly appreciated.

J

What editor did you use to create the file? Was it created by a windows application?

The guess by tredegar was good! The problem arises due to the different line terminators used by windows and unix systems (details here). Try the command
Code:
dos2unix simpTask.sh
then run the script again.

Then you might need to use dos2unix to convert it to the unix format. Or just use a linux text editor to create it, or an editor that can save the files with linux line endings. DOS/Win uses carry return AND line feed to mark a new line, Unix/Linux use just a line feed character.

EditPad Lite is one that I know of that can do that.

Suitable editors for writing scripts / programs:
kate kwrite (if using KDE)
nano vi vim (if using a terminal)
But there are 100's more.

What's the gnome default GUI editor? I forget.

Now who is going to complain that I haven't mentioned ..... ( emacs comes to mind )

The GNOME editor is gedit.

dos2unix on file didn't change the outcome -- still could not open

downloaded editpad lite, saved as unix file, ./simpTask.sh results in "file not found" but vi simpTask.sh shows file

xwin won't allow me to open nedit -- and before resorting to using vi, or one of those text editors that I find painful, I thought i'd fish around to see if there were any other ideas.

I thought you wanted a text editor for Windows, that's why I mentioned EditPad Lite.
P.S.
Ooops, just reread your post again.
