shell execution errors, permissions?

[webmasterp]

I have a perl script that I execute from php when a user requests a certain time period.

The perl script builds a list via ls and append (>>) (has to because the list is so long) and then runs a program called cdf2d2cfag_list, which is where the error is...

Ok, it runs the ls list builder then cdf2d2cfad_list uses that list as input to build a special data file. However, when the perl script tries to execute the program, it returns this error:

ksh: /home/disk/user_www/dpodhola/cdf2d2cfad_list: cannot execute

So, I moved the execution of the program into the php code and out of the perl to see what happened. Same thing, but different shell:

sh: /home/disk/user_www/dpodhola/cdf2d2cfad_list: cannot execute

I tried giving it 777 permissions and it still didn't work. Does anyone know why my C program won't execute?

could be a few things.. probably permissions.

i'll assume you have tried running it in a cgi-bin or similar directory.

i think the "web user" must have permission to execute on the directory where the file is .. as well as the file itself.

if you haven't done so, chmod the directory that the file is in.

if it's none of that, then good luck =)
