Hi,
Is there any simple way to undo an rm
command?
The question is purely theoretical; I have NEVER deleted the log of a benchmark queue who took a whole lunchtime to run.

On ubuntu or similar:
$ sudo apt-get install trash-cli
$ alias rm=trash
Then put that alias in .bashrc or the appropriate login script for your shell of choice.
The trash-cli
package is a command-line interface to the same trash can that GNOME and KDE and other use. So anything you delete via the trash
command can be restored by GNOME/KDE and vice-versa.
The other commands in the trash-cli
package are trash-list
, trash-empty
, and restore-trash
.
11+1 for trash-cli, -1 for aliasing rm. – None – 2010-02-15T14:48:37.457
1What's wrong with aliasing rm
? I like having an undo button for my accidental deletions, even on the command line. Also, trash-cli
explicitly facilitates this by accepting (and ignoring) many GNU rm
options.
Besides, the OP asked for a way to undo rm. This solution doesn't answer the question correctly without the alias. – Ryan C. Thompson – 2010-02-19T23:21:41.483
16@Ryan: Because you get used to rm to meaning something different than what the rm command really does, and then you make a mistake when it isn't aliased. Get used to using the trash command instead and that can't happen. – None – 2010-03-21T06:02:30.773
5@Roger: Or...you can alias rm
and then hypnotize yourself into forgetting that you did. That way you can still keep using rm
as though it's final.... but if you slip up and go "oh noes!!" you're not completely screwed. (i.e. don't rely on it's "recoverable" functionality) – mpen – 2010-06-23T18:36:47.413

@RyanThompson: This is a nice tip, but how to configure this to work also with sudo rm
? – takeshin – 2010-09-25T12:20:24.620
Hopefully you'll have an answer to that soon enough: http://superuser.com/questions/192725/how-can-i-alias-a-command-for-sudo
– Ryan C. Thompson – 2010-09-25T18:06:40.190@Roger you could consider set up an alias to enable undo for 3rd party scripts. – Lucas – 2014-01-31T22:28:00.027

The traditional answer is:
You recover the file from the latest backup. You do have a recent backup, don't you?
because on many unix filesystems this simple isn't possible, or is very difficult.
As others have noted this is not the end-all and be-all of the issue any more, but not making mistakes of this kind is still the preferred approach.
Thats a cool question... I usually don't make backups of ~/Downloads... and wiped out my content by passing rm -fr *(1)*
... every file wen away. So having backups is not always the solution. Trash-cli sounds cools. – m3nda – 2016-01-11T21:03:34.190
No, having backups is ALWAYS the solution. Just because you chose not to backup something, doesn't make backing up not the solution, it makes you silly, for not backing up something. – djsmiley2k TMW – 2017-06-06T14:57:09.817

3The modern answer is: Recover the file from a recent filesystem snapshot. :-) – knweiss – 2009-08-30T14:57:24.007

To prevent hypopthetical future mistakes, you might want to alias rm to rm -i...
I usually delete files on purpose, I just realize I needed those files later. So interactive wouldn't help – andrewtweber – 2015-12-13T22:25:25.677
6I generally think that this would never prevent any errors (the 'y' is typed quite automatically), but consume a lot of time, and encourage the use of He-Whose-Name-Must-Not-Be-Mentioned rm -rf. – Adam Matan – 2009-08-30T14:48:59.140
It does give you one extra go though before messing things up. I generally just ls
with the same parameters before so I can see what's going to go. – Rich Bradshaw – 2009-08-30T15:40:46.027
