Upvote for “sudo !!” No one ever seems to know about “!!” And it’s such a useful command.

I personally found out about it when I wrote a bash script that contained a password with two exclamation marks and I wondered why the last command kept being concatenated to the end of the password.

Also checkout thefuck for fixing other various typos

My install of Endeavour doesn't have it, and I haven't been able to figure out what package to install to add it. Also haven't tried very hard cause it's just a minor convenience but if anyone knows ...

Oooh it's cause I'm using fish isn't it? Is there a way to add it?

Had to check since this is something I've been wondering myself, but apparently not possible. From the fish FAQ:

Because history substitution is an awkward interface that was invented before interactive line editing was even possible. Instead of adding this pseudo-syntax, fish opts for nice history searching and recall features. Switching requires a small change of habits: if you want to modify an old line/word, first recall it, then edit.

However, for the use case here, with sudo:

As a special case, most of the time history substitution is used as sudo !!. In that case just press Alt+S, and it will recall your last commandline with sudo prefixed (or toggle a sudo prefix on the current commandline if there is anything).

Some people never get to experience the joys of squinting into a screen 4 inches away from your nose to inspect a long ass command. It’s the simple things in life

npm install

Vomits kernel

Okay let's try that one again, from the top

doas !!

[-] Illecors@lemmy.cafe 0 points 1 year ago

I used to do sudo !!, but then I've started learning the shortcuts of my shell a bit more - Ctrl+A jumps to the beginning of the line, which, technically speaking, is a saving of 1 (!) keystroke, compared to Shift+1+1.

This has also led to discover that emacs is actually much more useful compared to vim as it uses the same shortcuts.

[-] hedgehog@ttrpg.network 1 points 1 year ago

If you already submitted the command, you’ll have to hit Up first to have a line to jump to the beginning of, though, so it’ll be the same number of keystrokes either way.

I do the same thing you do, just with vi-mode keystrokes (up, then esc-I).

Why does sudo !! never work for me?

[-] metaStatic@kbin.social 2 points 1 year ago

Username is not in the sudoers file. This incident will be reported

What she'll are you using?

[-] null@slrpnk.net 1 points 1 year ago

I thought I'd tried it in bash, but I think I must have only tried it in fish
