File permissions
Hello Techies,
I am trying to modifiy the file permissions on some files which are
not owned by owner of the cgi-script. To be more precise, my cgi-
script runs as "wwwrun.www" and I would like to "chmod" a file
belonging to "XXX.users". I am trying this on Apache/cgi script using
Perl/Linux.
I am sure that I am trying something *against* the basic file security
mechanism, but I have such a requirement and would like to know if
there is any way of achieving the same. I do not need to strictly
achieve the same from within my cgi-script, cgi->calls->shell/batch
script which inturn manipulate the file permission is also agreeable.
Can anybody throw some light on the issue?

Try setting the "Sticky bit" of the file. I think it works on unix,
however I am not sure about linux.

File permissions
Try this;
when u try to alter a file from web - you in user group apache
the file ur collection give the user:group as userA:Apache
In this manner we access can change the user permission
example from userA want to switch file to userB
u can chmod userB:Apache - this will do the job
