Re: How do I check if another user can access a file?

in reply to How do I check if another user can access a file?

I would write in a sub in perl:

• Get (and read manual) stat from file (permissions, user and group owner)
• If user is the owner, verify r/w permission with S_IRUSR S_IWUSR masks and fix if don't have permission you want
• If user is in group owner (getgrnam), then verify r/w permission with S_IRGRP S_IWGRP masks and fix if don't have permission you want
• If user is not in group owner, then verify r/w permission with S_IROTH S_IWOTH masks, and fix with system and adduser from your S.O.

But probably you should simplify your environment and make a good use of groups and umasks ;)
