I'm writing a file browser script. I've learned about chmod and unix permission numbers and what they represent. But how do I determine the owner, group and other permission settings.
Is there a perl module that makes this chore easy?
Thanks Tricia
There are a few. If you are interested specifically in the Unix permission model, though, you might want to work with the output of the ls -al command. The permission string is at the left of each line returned, and has 10 characters, first the directory, then the r [read] w [write] and x [execute] permissions for owner, group and world respectively.
By taking the substring from each line, then, you can parse each for the permission appropriate to each category.
This is the *wrong* way to approach getting the permissions for the file, the 'stat' builtin will do the same thing and does not require shelling out nor screen scraping.
perldoc -f stat perldoc File::stat
