I didn't test it, but the destination file opening line in that module is: `open($to_h,"> $to\0") or goto fail_open2;` [download] so it should override the file ... Enjoy, Mickey	[reply] [d/l]

dear monks, `copy("c:\\dir1\\text.errmsg", "c:\\dir2\\text.errmsg") \|\| die "Can't open text.errmsg:$!";` when i ran the program, it creates the file and copied the content. next time i ran the program (destination file is existing now ) it is giving error message. Normally it should overwrite it ,but it is not happening here.. can u explain in detail??	[reply] [d/l]

`copy` will check if the destination file exists. I don't think exists a parameter for overwrite destination file. Maybe you want this: `unlink $destfile if -f $destfile; copy($origfile, $destfile);` [download] Update: This is a workaround. As mickeyn said at Re: help needed in File::copy, File::Copy should overwrite destination file. Igor 'izut' Sutton your code, your rules.	[reply] [d/l] [select]

If I understand properly, you should check the file permissions after it got created the first time. It is probably set to read-only for user. See the umask function for details. -imran	[reply]
