Description: The -w test will do:
if (-w FILEHANDLE) {
print "It's writeable by my effective uid or gid!\n";
}
This code was credited to chromatic by the author. --Ed.Answer: How do I test if a file has write permission?
contributed by fx Another, but probably less efficient way, is to open the file in append mode. If the open fails the file COULD be read-only:
open(FILE, ">>some_file.txt") || print "File is read only";
The advantage of this way, I suppose, is that if you really want to write things to the end of the file then it's now open :) |
