A ./ problem

Postby tukkek » 2005-12-17 17:06

Hi there,
I've just migrated to Debian from the Kurumin distribution, where when I wanted to run a shell script, I ran
from the konsole.

Now, when I try to do this, i receive:
bash: ./script.sh: /bin/sh: bad interpreter: Permission Denied

My /bin/sh is a link to bash ( /bin/sh -> bash ), and I've also tried to change it to /bin/bash ( /bin/sh -> /bin/bash ), but the result is the same, as it's too when I use the
command as root.

I can use
sh script.sh
normally, but if somebody could tell me what's happening, I'd be very happy.

Can you post the first line of your shell script?

Does your shell script have the complete shebang line, like this:


Does the shell script have the correct permissions to be executable?

It's not a single script that doesn't work with ./ - it's every single one I try to run.
And yes, all of them have the proper permissions and the #!/bin/sh as first line.

By the way, is this called a "shebang line"? Never heard of it. Why is that?.

What does ls -l /bin/sh /bin/bash ./script.sh give? And cat /proc/mounts ?

And shebang is shorter way to say 'hashbang', which is 'haSH' 'bang', or the names of the characters '#' and '!'. See http://en.wikipedia.org/wiki/Shebang for more information.

Gotta love Wikipedia! Thanks for the link - I feel better as a geek now.

Maybe it's useful I mention again that even as the root user I still get the same error. For the outputs:

$ls -l /bin/sh /bin/bash ./script.sh:
-rwxrwxr-x 1 root alex 649556 2005-10-13 14:58 /bin/bash
lrwxrwxrwx 1 root root 4 2005-12-14 16:25 /bin/sh -> bash
-rwxr-xr-x 1 alex alex 645 2005-12-15 14:10 ./clean.sh

$cat /proc/mounts:
rootfs / rootfs rw 0 0
/dev2/root2 / reiserfs rw 0 0
proc /proc proc rw,nodiratime 0 0
sysfs /sys sysfs rw 0 0
devpts /dev/pts devpts rw 0 0
tmpfs /dev/shm tmpfs rw 0 0
/dev/sda6 /home xfs rw 0 0
/dev/sda2 /mnt/sda2 xfs rw,nosuid,nodev,noexec 0 0

Who is alex?
Why does he own bash?

# chown root:root /bin/bash
# chmod 755 /bin/bash

I'm alex, dawgie
It was just a test to see if I got better results owning the bash or it's link /bin/sh, but doesn't seem to be the case.

I can't run any shell script from Konqueror either, as it returns me the same error.
