Changing file permissions in a script

ITmajor has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I am trying to run a CGI script but my program dies on this line:

open(IMAGE, ">/somedir/$graphfile.png") or die "$_";
[download]

I think it is because of the file permissions. When I run my script from the command line I get no problems. When I run my script from the browser the program dies and says permission is denied. Is there a way to change file permissions for files created within a script? If not, what might be the cause of death?

The user that runs the CGI under the web server doesn't have permission to write files to `/somedir/`. If you don't mind having it globally accessible to everyone, you can set the permissions this way: `chmod 777 /somedir/` [download]	[reply] [d/l] [select]

How do I change the user that CGI runs under? That's a matter of web server configuration. You haven't mentioned which web server you're using, but the documentation for it can probably tell you how to do that.	[reply]

And this surely isn't right- `open(IMAGE, ">/somedir/$graphfile.png") or die "$_";` Try- `open(IMAGE, ">/somedir/$graphfile.png") or die "Couldn't open /somedir/$graphfile.png for writing: $!";` [download]	[reply] [d/l] [select]
