Preventing Accidental File Deletions
Many of us learned the hard way that
rmdir are unforgiving. There’s no Trash to recover from, and there’s no undo.
There are many legendary stories involving
rm -rf disasters.
In time you learn to be wary of using those commands, but once in a while you’ll screw up and delete something you shouldn’t have.
There are a few articles about how to alter the behaviour of
rm so that it moves to the trash instead of permanently deleting. But this is dangerous if you happen to be using a different machine which doesn’t have this behaviour enabled.
A better option is to install rmtrash (also available via Homebrew). The
rmtrash command can be use to delete both files and directories, and as the name suggests it moves the files to the Trash instead of parmanently deleting them.
If you really need to call
rmdir then just provide the full path, e.g.
You can then alias the actual
rm commands to give you a reminder warning, for example add this to your
Over time this should get you into the habit of typing
This change might cause problems with shell scripts which use
rm. I’m not really sure how to deal with that. It may be sensible for the alias to return false to indicate the command failed.
