When I try to run a script I just wrote (or a cron job last night that used to run fine)...

I have this same problem! It happens when i'm trying to run a script for VNC, and I cant start the ut2004 demo because of it. Probably other times too.
Anyone figure out how to fix it?

I'm finding it also affects perl scripts with #!/bin/perl as the first line.

I did try to remerge bash and that didn't make a difference.

I had this exact same problem ( /bin/bash: bad interpreter: Permission denied) when I had a seperate /home partition and I was trying to compile something from source.

I have no idea why, but it seems like something doesn't like being on seperate partitions. To fix this I just made /dev/hda7 (my home dir) to mount /mnt/home, then I did a mount /mnt/home /home --bind and my problems were fix.

The problem is that other partitions that are mounted don't get mounted with the 'exec' flag.

I had to put the following in /etc/fstab to get my other partitions to be able to run anything set to +x:

cram, chock that up to memory error. I just typed it wrong here, I have it right there. In fact it used to run, but no longer.

RJG, I added the exec option in /etc/fstab. I'll try to remember to come back and mark this resolved if it works next reboot. I've got too much running at the moment.

It seems funny that it would have used to work without that. My home directory is on NFS so maybe that has something to do with it. :-)

Wow, the fstab was the last place I would think to fix a problem that only seems to appear with bash... but it fixed it for me.
Thanks for the help!

Thanks for the fix. I want to mention in case it helps someone else that you need to put the exec or suid flags after user or users in /etc/fstab.

After catting /etc/mtab the first 10 times in disbelief I decided to investigate why the hell the flags weren't taking effect, and it's because of the order. The user/s flag resets back to noexec, nodev, nosuid.
