Re: How do I test whether or not a file is writable?

[kiruthika.bkite]

 if(-f $name )
    {
        if(!(-w $name))
        {
            print "File '$name' doesn't have write permission\n";
        }
    }

-f switch is used to check whether $name is file or not.
-w switch is used to test whether file has write permission or not.

There's no point testing for both -f and -w. If the file doesn't exists (or if its existence cannot be determined), -w will return false. And if -w returns true, the file exists.

Yes, but -w would also return true if the file is actually a writeable directory
