I have a problem that I think is file permission related, I am just not sure how to go about figuring out which file has the problem, and I don't want to have to re-install the OS. I am running Fedora 3.

If I run the following shell script:
#!/bin/bash
echo "Hello"

I get nothing, but if I comment out the first line:
##!/bin/bash
echo "Hello"

I get Hello on the screen. If I run the first script from inside Apache, I get a permission error. The problem is that I need to have the first line in to run my CGI scripts and for some reason they won't execute if a shell has t be spawned.

The problem appears to be permissions, maybe with a lib file, but I have checked numerous files and made a few changes, returning them back the way they were, all to no avail.

If anyone has any suggestions on tracking this down, I would greatly appreciate it. I have to have this demo web server working by noon tomorrow for a demo!.

TIA

You could try running strace on the script:
strace /path/to/script

Also make sure that the user you are runnning the script as has read and execute privilages.

I appreciate the advice of using strace. To respond to your question of user permissions, I have resorted to testing as root until I get the issue resolved.

In regards to the strace, this looks like it might give me some insight. I am running the strace on a Fedora machine that works and on the one that doesn't work and see that the traces are different. Can you please tell me how to get the output into a file? The > symbol just puts the Hello into the file. If I can get this into a file, I can do a diff and see the differences.

Thanks, I feel like I am getting a little closer.

Well if it puts "hello" into the file then surely it is working?

You can output an strace into a file using "-o /tmp/bash.trace"

Thanks again for the info. I should have looke dthat one up. Unfortunately, I am down to the wire to get this machine working.

The hello is on the working system. The one we are trying to get working is blank.

Here is the most obvious error on the one that isn't working.
ioctl(1, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfe0d03c) = -1 ENOTTY (Inappropriate ioctl for device)

Any ideas?

Thanks

Norm

Here are the actual 2 error lines that appear to be the errors that in the non-working version, but not in the trace of the working script:

open("/dev/tty", O_RDWR|O_NONBLOCK|O_LARGEFILE) = -1 ENXIO (No such device or address)
ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbffad450) = -1 ENOTTY (Inappropriate ioctl for device)
