simple shell file

jbwells7474 · 08-23-2009, 10:52 AM

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.

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

Windows notepad....saved as an ascii file.

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.

Go on then, I'll do it.
Hey, why haven't you mentioned Emacs?

He did

Oh yes...

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.

jbwells7474 · 08-23-2009, 01:39 PM

ideally, i would prefer to do it in windows...and i did download editpro to windows...and i thought i saved the file as linux, but evidently i failed
