Daftar Isi

• unlink LIST

• unlink

  Deletes a list of files. On success, it returns the number of filesit successfully deleted. On failure, it returns false and sets $!(errno):

   my $unlinked = unlink 'a', 'b', 'c';
   
   unlink @goners;
   
   unlink glob "*.bak";
   

  On error, unlink will not tell you which files it could not remove.If you want to know which files you could not remove, try them oneat a time:

   foreach my $file ( @goners ) {
   
   unlink $file or warn "Could not unlink $file: $!";
   
   }
   

  Note: unlink will not attempt to delete directories unless you aresuperuser and the -U flag is supplied to Perl. Even if theseconditions are met, be warned that unlinking a directory can inflictdamage on your filesystem. Finally, using unlink on directories isnot supported on many operating systems. Use rmdir instead.

  If LIST is omitted, unlink uses $_.
