    Ctrl + R is bash history search

    [–] [email protected] 95 points 1 year ago

    That sounds an aweful lot like typing to me

    [–] [email protected] 45 points 1 year ago (2 children)

    Keep hitting CTRL+R until you find it and you can hit CTRL+S to scroll forward if you went past it πŸ‘Œ

    [–] [email protected] 54 points 1 year ago (1 children)

    I've used ctrl R for 20 years.

    Now I learn of ctrl S. This is a blessed day!

    You know you're allowed to read the docs, right?

    [–] [email protected] 63 points 1 year ago

    read the docs

    NNNNEEEERRRRDDDDD

    [–] [email protected] 20 points 1 year ago (1 children)

    One day of figuring it out avoids 30mim of reading a doc!

    [–] [email protected] 3 points 1 year ago

    Surprised they hadn’t hit the other hot key by accident myself. That’s usually how I find out about other/new features.

    [–] [email protected] 4 points 1 year ago

    Yeah. Read the docs. That's how it starts. Then before you know it your captain is slapping you in the face because you had the nerve to ask to be allowed to sleep instead of driving the giant robot all day.

    [–] [email protected] 3 points 1 year ago

    Reading sounds a lot like typing, only in reverse.

    [–] [email protected] 5 points 1 year ago* (last edited 1 year ago) (1 children)

    Or CTRL+SHIFT+r, CTRL+s just pauses my terminal output, you can unpause it with CTRL+q

    [–] [email protected] 3 points 1 year ago

    I was gonna say I always used Ctrl+shift+r.... didn't even know about control+s being s thing...

    [–] [email protected] 14 points 1 year ago

    Ctrl + R ls

    [–] [email protected] 7 points 1 year ago (1 children)

    Use fzf for an improved experience!

    [–] [email protected] 3 points 1 year ago (1 children)

    So basically this? It's absolutely amazing. Just be warned that it replaces ctrl+R AND up arrow shortcuts by default. You can easily disable the up arrow though.

    [–] [email protected] 3 points 1 year ago

    I've not heard about atuin before but seems to do the same thing. I don't know the specific differences.

    [–] [email protected] 4 points 1 year ago (2 children)

    I prefer to just speak to my computer instead of using a keyboard. The computer doesn't respond but maybe one day

    [–] [email protected] 3 points 1 year ago* (last edited 1 year ago) (3 children)

    A speech operated terminal would be possible, speech to text is pretty well developed by now, shouldn't be too hard to hook that up to a terminal.

    But, y'know, effort.

    [–] [email protected] 3 points 1 year ago* (last edited 1 year ago)

    Precisely, I gotta type in order to go find a program that does that or write one myself. I will simply continuing speaking to an unyielding electric box until it gains sentience and responds.

    You can Ctrl+R, type "ls", then keep hitting Ctrl+R until you find one without arguments if you need them. Efficiency at its finest.

    [–] [email protected] 9 points 1 year ago

    I usually bind it to my up arrow. Means I can still keep tapping up ;)

    [–] thepianistfroggollum 8 points 1 year ago

    Thank you for this

    [–] [email protected] 25 points 1 year ago (1 children)

    Jfc, how did they film me?

    [–] [email protected] 3 points 1 year ago

    You're in the Matrix

    [–] [email protected] 25 points 1 year ago* (last edited 1 year ago)

    Me last Thursday:

    user@work5:~$ [CTRL-R] ls

    user@work5:~$ ls

    me: "That will do..."

    [–] [email protected] 19 points 1 year ago (4 children)

    id type out more ~/.bash_history | grep ls and copy, paste before id type out ls tbh

    [–] [email protected] 7 points 1 year ago* (last edited 1 year ago) (4 children)

    Why do all that typing? Hit ctrl-r first then type ls. Bonus points if you hook fzf into it.

    fzf hooked into ctrl-r, a bash history of about 100k and HISTCONTROL=ignoreboth is magic.

    Note: backup your history file periodically, system crashes at the wrong time can zero it leaving you incompetent until it's restored.

    Last week I switched to a new distro and decided to nuke everything except my personal data in my backup. I immediately regretted not saving my shell history file.

    alias l=ls so you can finally breathe

    [–] [email protected] 19 points 1 year ago* (last edited 1 year ago) (1 children)

    alias ls = "cat ~/.bash_history | grep ls"

    Edit: Even better: alias ls = "$( cat ~/.bash_history | grep -x ls | tail -1 )"

    Then you try this on Windows and are disappointed that it doesn't remember anything from your last session.

    My Powershell history broke yesterday after a very intense git session ;-;

    [–] [email protected] 11 points 1 year ago (1 children)

    Looks more like trying to get into the bios

    [–] [email protected] 21 points 1 year ago* (last edited 1 year ago) (3 children)

    One finger is not enough for that, could be ESC, F2, F12, DEL or whatever else the bios manufacturer landed on when they threw a dart at the keyboard.

    [–] [email protected] 9 points 1 year ago (1 children)

    Roll your face across the keyboard repeatedly

    [–] [email protected] 9 points 1 year ago (1 children)

    It's more reliable than guessing the key.

    If you're on an EFI based system and have systemd, you can use systemctl reboot --firmware-setup to get into BIOS!

    L and s are on the other side of the keyboard and I only have one hand free. Too much work.

    Ctrl-r

    That said... I didn't discover it so early as I should....

    [–] [email protected] 3 points 1 year ago

    Ouff... way too accurate.
