Hoping for this feature....

Posted by Sufficient_Ad7816@reddit | linux | View on Reddit | 15 comments

Hi! I recently came over from Windows 10 to Linux Mint and really like it for multiple reasons. One thing I've found that I'd ask why couldn't be implemented is a windows like command ctr+z to undo previous command. Once you do something in Linux, that's it, no take-backs. Is there any enthusiasm for adding this feature?

Can you clarify what you mean? I checked OnlyOffice, Text Editor, Files, and a couple others and ctrl-z works fine on them. Can you give an example where you try to ctrl-z and nothing happens?

He said "previous command", I'm scared he might be referring to terminal commands

lol no I wasn't talking terminal commands. I mean to things like file structure deletions. In Windows if I accidentally delete a folder, if the VERY next move I type "ctr+z" I can undo the mistake...

Oh, don't mind me then. I'm pretty sure you can do that on Linux tho? Idk, I use the terminal for most file/directory-related operations. Maybe it depends on which file explorer application you're using? I'd be a bit surprised if this was just entirely not a thing on Linux, but I'm unsure, I'll test it tomorrow in Dolphin.

You don't have to. I use this feature on Dolphin nearly daily

no such thing, to answer your question "ask why couldn't be implemented":

each command does not specifically say what it did. you would have to somehow keep a log of what each command does.

but wait...

what happens if you run commands at the same time, modifying the same resources? using HH:MM terminology to make it easier to parse

Terminal 1: * 1:00: echo 'test' > /tmp/somefile * 1:02: rm /tmp/someotherfile

Terminal 2: * 1:01 mv /tmp/somefile /tmp/someotherfile

if you undo terminal 2 at the end, /tmp/someotherfile was already removed.

this is a very simple example of a very complex problem: parallelism. in short: many things are happening to your computer at once. the commands are not exclusively entered by humans and which were executed as things were at a specific point in time. there is such a thing as snapshoting at the filesystem level, but it would be totally asinine to do after every human command. you could just, as the human, take a snapshot before you do anything risky and remove it once you know everything works.
