Wow this is really validating for me to read. I’ve been using Linux for a few years but I’m definitely not a computer expert and am intimidated by the command line.

I’ve always felt like googling every command and arrowing up to find an old entry rather than just googling it again marked me as a fake Linux user, not a real one.

Lol don't feel bad, I can do advanced crazy shit with Linux like pivoting the running OS into RAM so I can unmount the boot drive to do whatever without ever rebooting

But I still [Web Search] commands a shit ton of the time LMAO

You can use Ctrl-R and Ctrl-Shift-R to search through your history instead of having to push up a bajillion times.

You have to be a linux user to use the console now?

[–] iAvicenna@lemmy.world 5 points 1 week ago

history | grep then !cmd no

[–] nullPointer@programming.dev 4 points 1 week ago

zsh tab completion also looks through history wich is pretty nice.

I accidentally found out one day that I could use a wildcard operator in the terminal instead of a full file or folder name due to always doing this.

cd Pho* or cd /documents/Pho*

Will for example open my "Photo Examples" folder in the working directory or based on the path

[–] merc@sh.itjust.works 6 points 1 week ago (2 children)

With ZSH there's something called "path-completion" that makes that even easier.

Say you want to go to "/usr/local/share/fonts" but that's too much to type out, you can instead type "cd /u/l/s/f" and hit tab. If every path element is unambiguous it will just expand it to "/usr/local/share/fonts". In this case though, "/u/l/" can expand to "/usr/local" or "/usr/lib" so when you hit tab it moves the cursor to just after the "l" to indicate it needs you to distinguish between "/usr/local/" and "/usr/lib". If you just type "o" and hit tab again, it will know that there's only one match for "/usr/lo" and expand that to "/usr/local/" Then there's only one match for "s" which is "share", and only one match for "f" which is "fonts".

That avoids the danger of executing a command with an asterisk wildcard.

You can use || between two commands as well. If the first command returns exit code != 0, the second command will run.

I.e. which ansible || pip install ansible.

[–] merc@sh.itjust.works 4 points 1 week ago

Or && for if you only want the second command to run if the first command succeeded.

This only works until you grow an addiction to making pho at home and start documenting your progress.

cd "Pho Recipes and Pictures"

[–] DarkAri@lemmy.blahaj.zone 3 points 1 week ago* (last edited 1 week ago) (1 children)

cd /

sudo rm -rf *

Basically the Linux version of deleting system32 but idk I'm not a super Linux nerd yet.

[–] bandwidthcrisis@lemmy.world 5 points 1 week ago

The fun thing is that you can create a file named "-rf *" and hope an admin tried to delete it!

zsh-autosuggestions
history | fzf
alias cat="bat --plain --theme=gruvbox-dark"

[–] zarkanian@sh.itjust.works 6 points 1 week ago* (last edited 1 week ago) (1 children)

Aliasing cat or any other ubiquitous shell utility to a replacement is a mistake. Garuda did this, and it was driving me crazy why cat was giving me errors. Turns out that they had aliased bat to cat, and since bat is a different program, it didn't work in exactly the same way, and an update had introduced some unexpected behavior.

Drop-in replacements are dumb. Just learn to use a different command.

[–] janAkali@lemmy.sdf.org 3 points 1 week ago* (last edited 1 week ago) (3 children)

I think it's ok to add this in a personal .zshrc, not on a distro level:

If it breaks something - I'd probably know why and can easily fix it by removing alias/calling cat directly.

Also, scripts almost always use bash or sh in shebang, not zsh. So it only triggers if I type cat in terminal.

I write part of the command then ctrl+r. Using FZF mind you. Such a great utility.

[–] dreadbeef@lemmy.dbzer0.com 4 points 1 week ago

Fish once again undefeated. If I want to find that weird image magick command I used earlier with foo.png in it I just type foo.png, hit up and its usually the first one. It doesnt matter where foo.png occurs in the command, fish will find it.

[–] stealth_cookies@lemmy.world 3 points 1 week ago (1 children)

This is why I like atuin, I can just press up and start typing part of the command and it will likely find it in my history.

Oh come on! I at least type the beginning so that it filters the history

[–] wewbull@feddit.uk 3 points 1 week ago (4 children)

The one people see me doing that gets a "huh?" Is:

~$ !find
find -type f -name '*blah*' -print0 | xargs -0 gzip
~$

"Wait! What did you do?" "Oh. Do you not know about bang?"

Being able to just enter a partial command, and hit [up] to jump to prior commands that started in the same way in zsh is a godsend.
