"cannot execute binary file" bash script

[hans1967]

Hi Community,

got message "cannot execute binary file" when trying to start a simple bash script. I know all linux forums good advices towards this theme. But these did not help. To come to the point: I had edited and saved the script with OpenOfficeWriter. MousePad and Pico alias Nano did not show any text format problem. But my way of fixing the Bug proved: It must have been just that. I deleted the file and wrote it completely new using MousePad. That solved the Problem. Hope I can help someone with this posting.

Best regards,

Check the permitions of the file and whether you have the executable flag set. Also make sure you have:

#!/bin/bash

at the beginnig

What could have happened is OpenOffice put a character which was undisplayable by your editors in the file, and because of that it was thought to be something that it wasn't. Things like that can sometimes get confusing.

You will also experience this problem if you mounted your partition as noexec.

fanus@schoonees:~$ ls -l toets.sh
-rwxr-xr-x 1 fanus fanus 43 2011-01-21 17:28 toets.sh

fanus@schoonees:~$ ./toets.sh
bash: ./toets.sh: Permission denied

fanus@schoonees:~$ mount | grep sda8
/dev/sda8 on /home type ext3 (rw,noexec,nosuid,nodev)

fanus@schoonees:~$ cat /etc/fstab | grep sda8
/dev/sda8 /home ext3 user,rw 0 2

Reason:
noexec Do not allow direct execution of any binaries on the mounted
filesystem. (Until recently it was possible to run binaries
anyway using a command like /lib/ld*.so /mnt/binary. This trick
fails since Linux 2.4.25 / 2.6.0.)


Problem solved by remounting the partition with /etc/fstab:

fanus@schoonees:~$ cat /etc/fstab | grep sda8
/dev/sda8 /home ext3 users,exec,dev,suid 0 2
