Answer: How do I test whether or not a file is writable?
contributed by chromatic

The -w test will do:

if (-w FILEHANDLE) { print "It's writeable by my effective uid or gid!\n"; }
For more information, see -X (or perldoc -f -X).

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.
