I honestly feel pity for the Windows using friends I have in cases like this. A typical example is when they start writing "File Renamers", to mass rename collections of files (i.e. mp3 audio) and start being bitten by bugs in the renamer itself. Another typical example is what I call the robo-user. A person who starts training his fingers and/or brain to repeatedly hit the same sequence of keys in the keyboard, in an effort to rename dozens of files within Explorer. Writing shell scripts to do the job is not necessarily easier, since you have to learn the tools that are available and learn all about the ways they can be glued together, before becoming *really* productive. It pays a thousand times back though, when you start doing in a couple of lines what would take hours of error-prone, manual labor. This is why I have been heard saying: "Unix is for lazy people. So lazy, in fact, that they start learning languages and tricks to avoid as much work as possible, by making their computers do it." _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
