That's a good idea, and I'm going to do just that. Although, in this case, it probably wouldn't have worked perfectly. I assumed I was in a different directory and ran rm *. I rm'ed when I wanted to, just not WHERE I wanted to. :-) This is what happens when you're holed up on a Saturday afternoon writing scripts instead of playing outside. -- ---Bryen--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Somebody out there who's tried this ?

I seem to recall from the days preceding recorded history of my linux usage that libtrash had some problem with mutt. In any case, when you use libtrash you'll still have to empty the trash periodically, and then someone will empty trash containing a file they wanted and the thread topic will be "undoing a libtrash delete" rather than "Undoing a delete" :) It's really aliasing rm which is the most effective solution, coupled with backups.

Shouldn't that be in dot profile or dot bashrc so it persists between konsole secessions? ___ _ _ _ ____ _ _ _ | | | | [__ | | | |___ |_|_| ___] | \/ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I've known users (dare I say, "lusers") to override rm with a script that moves the target files to a trashcan folder.

Hmm... That would be an interesting project to try to create. What a way for me to flex my current knowledge and expand on it. :-)

It's no big deal. Write an "rm" replacement script that moves files to a specified trash folder rather than simply unlink them. The only thing you really have to worry about is name clashes. When that happens, add a suffix (making sure that the suffix is unique, of course). With a bit more work, you could additionally mimic the file system hierarchy within the trash folder, but that doesn't get you out of handling multiple deletes of the same name (since files often get recreated after they're deleted).

So how would a script called rm not conflict with the real rm McCoy? Nothing to you, but I'm just starting to get into scripting. :-) Critique me here. As I'm going by theory. I would move the current /bin/rm to a new location. Then I would create an rm script and place it in /bin where the current rm was located. But within the rm script, I would point to the rm command's full path when using rm's functionality. Thus users would never see the difference when they run /bin/rm, but the script does the interpretation to /somewherelse/rm. Did I figure it out right? -- ---Bryen--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Whoa! No, no no. Never do that!!

No, just create a directory ~/bin (equally, $HOME/bin) and put your personal scripts there. Make sure that directory precedes the stock directories in the PATH variable. (I don't recall if $HOME/bin is part of the stock PATH or not, but if it isn't, add a line like this to your "$HOME/.bash_profile" script:

PATH="$HOME/bin:$PATH"

...

No. Put it in ~/bin ($HOME/bin).

Well, the point is to avoid what the stock "rm" does and instead move the file to an out-of-the-way place from which you can retrieve it should you change your mind.

Uh. Keep trying.

Perhaps for someone as new to all this as you, playing around with replacements for key OS utilities isn't the best idea.

You could use Konqueror or ... what's it called? There's a Gnome file manager, too. They're GUIs that have trash cans and "Empty Trash" commands and all that usual stuff.

I'm not that new. Just new to scripting itself within Linux, but willing to take my chances and experiment (even break) to further my knowledge. As for GUI (Nautilus on GNOME), as Patrick pointed out, when rm-ing on the command line, it doesn't fall into the GUI trash can. Only when you delete within GUI. I double-verified this just to be sure. I didn't realize that you could create ~/bin which would take precedence over standard /bin. Now that I know, I can proceed a bit more safely. To me, this is an excellent trial/error exercise that coincides perfectly with my scripting studies. And I do appreciate the feedback you've given. Lots of good foundational information from you.
