Shell Tricks That Make Life Easier (and Save Your Sanity)

One thing I find life-changing is to remap the up arrow so that it does not iterates through all commands, but only those starting with the characters I have already written. So e.g. I can type `tar -`, then the up arrow, and get the tar parameters that worked last time.

In zsh this is configured with

    bindkey "^[OA" up-line-or-beginning-search # Up
    bindkey "^[OB" down-line-or-beginning-search # Down

Heh. I've done this since forever, but I use PgUp and PgDn so I can retain the original meaning of the up arrow key.

> Sync your shell history to all of your machines

I think of my shell history as very machine specific. Can you give some insights on how you benefit from history sync? If you use it.

an hour agoseedie

Same, I find shared history not very useful.

However what I do find useful is eternal history. It's doable with some .bashrc hacks, and slow because it's file based on every command, but:

- never delete history

- associate history with a session token

- set separate tokens in each screen, tmux, whatever session

- sort such that backward search (ctrl-R) hits current session history first, and the rest second

Like half my corporate brain is in a 11M history file at this point, going back years.

What I would love is to integrate this into the shell better so it's using sqlite or similar so it doesn't feel "sluggish." But even now the pain is worth the prize.

35 minutes agofoobarian

That feature is entirely optional and disabled by default. Atuin stores your shell history locally in a sqlite db regardless of whether you choose to sync it. I thought fzf was fast, but atuin makes it look slow by comparison.

39 minutes agoCyphus

This can also be achieved with `.inputrc`:

    "\e[A": history-search-backward
    "\e[B": history-search-forward
2 hours agomoebrowne

That's a nice one.

One thing I do is configure my keyboard so that "modifier+{ijkl}" mimicks the inverted T arrows key cluster. So there's never a need for me to reach for the arrow keys. And {ijk} makes more sense than vi's {hjkl} and is faster/more logical/less key fingers travel. The nice thing is: as I do this at the keyboard level, this works in every single map. "modifier" in my case is "an easily reachable key in a natural hand position on which my left thumb is always resting" but YMMV.

I set that up years ago and it works in every app: it's gorgeous. Heck, I'm using it while editing this very message for example.

And of course it composes with SHIFT too: it's basically arrow keys, except at the fingers' natural positions.

I think it's a question of context and familiarity. To a vim user, like me and, I assume, ahmedfromtunis, their examples do indeed seem simple and natural.

I've been a (n)vim user for 20+ years now, but I hate vi-mode in the shell. However if I feel that I need to do a complex command, I just do ctrl-x+e to open up in neovim (with EDITOR=nvim set). I find it a good middle ground.

> <esc>cc

Doing control+o in insert mode temporarily places you into normal mode so that you can execute one normal-mode command, and then go back to insert mode again--no need to hit 'i' again.

So, instead of '<esc>cc', '<c-o>S'.

4 hours agopenguin_booze

The vim version is much easier, if you ask me: 3 strokes, 2 keys and 0 combinations.

The one you suggest however requires 4 strokes (ctrl then o then shift then s), 4 keys (ctrl, o, shift, s) and 2 combinations.

The "cc" sequence deletes the line and switches automatically to insert mode. To forgo the switch, the sequence then becomes "dd".

2 hours agoahmedfromtunis

Maybe I have my bash/readline vi mode configured specially to do this, but if I want to delete the entire line and type a new one (from anywhere in that line), I do something simpler than either of these alternatives:

<esc>S

Esc exits insert mode (of course) and capital S erases the line and puts you in insert mode at column 0 (just like in (n)vim, right?).

Like I said, maybe I configured that? But 'S' is standard vim-stuff... (I'm not able to double check my config at the moment).

[Edit: right after hitting submit I realized that my way is perhaps "arguably" simpler because I do have to hit shift to get capital S. So I'm also hitting three keys...]

2 hours agoratrocket

<c-o>S is also a vim sequence. The equivalent readline/emacs is <c-e><c-u> or <c-a><c-k>, or just <c-u> or <c-k> if you're already at the end/start of the line.

4 hours agoexceptione

I think it’s a difference in how people think. I can’t remember hotkeys. It just doesn’t compute. But with vim style bindings it’s much closer to writing a sentence. `3`, number of times, `b`, beginning of word, `c`, change, `w`, word. Yea it’s a lot. I cannot explain why it’s simpler for me to learn that than emacs style bindings but it is.

2 hours agoroxolotl

I don’t love vi-mode, but I’ll address your comment.

Many people these days, including yours truly, have caps-lock mapped to ctrl if held or esc if tapped. That’s good ergonomics and worth considering for any tech-savvy person.

Instead of the 3b I would type bbb (because I agree with you that typing numerals is a pain).

So (caps lock)bbbcw isn’t bad. It’s better than it looks, because if you’re a vim user then it’s just so automatic. “cw” feels like one atomic thing, not two keypresses.

And importantly, it doesn’t involve any chords.

I've somehow gotten by never really needing to pipe any commands in the terminal, probably because I mostly do frontend dev and use the term for starting the server and running prodaccess

3 hours agomkoryak

Pipelines are usually built up step by step: we run some vague, general thing (e.g. a `find` command); the output looks sort of right, but needs to be narrowed down or processed further, so we press Up to get the previous command back, and add a pipe to the end. We run that, then add something else; and so on.

Now let's say the output looks wrong; e.g. we get nothing out. Weird, the previous command looked right, and it doesn't seem to be a problem with the filter we just put on the end. Maybe the filter we added part-way-through was discarding too much, so that the things we actually wanted weren't reaching the later stages; we didn't notice, because everything was being drowned-out by irrelevant stuff that that our latest filter has just gotten rid of.

Tricks like this `\#` let us turn off that earlier filter, without affecting anything else, so we can see if it was causing the problem as we suspect.

As for more general "why use CLI?", that's been debated for decades already; if you care to look it up :-)

Not a fan of the LLM-flavoured headings, and the tips seem like a real mixed bag (and it'd be nice to give credit specifically to the readline library where appropriate as opposed to the shell), but there are definitely a few things in here I'll have to play around with.

One thing I dislike about brace expansions is that they don't play nicely with tab completion. I'd rather have easy ways to e.g. duplicate the last token (including escaped/quoted spaces), and delete a filename suffix. And, while I'm on that topic, expand variables and `~` immediately (instead of after pressing enter).

`CTRL + U and CTRL + K CTRL + W`

What I like about these key combinations is that they are kind of universal. A lot of programs on Linux and Mac support all these key combinations out of the box. And that's like a game changer in productivity, especially jumping to the start or the end of the line or jumping forward and backward per word is making working only with the keyboard so much more nice. And in editors together so AVY, you can even get a faster flow of jumping around.

The '-' shortcut is weird. In 'git commit -F -', the '-' is actually /dev/stdin.

`-` is the traditional shell way to refer to stdin/stdout (as with your git commit example) but also the traditional way to refer to the last directory you were in (as with git checkout/switch).

You would never pipe the output of a command to `cd` so the `-` shortcut couldn't be helpful to cd as-is. So rather than invent yet another shortcut to memorize for `cd` they reused the existing one which otherwise would be redundant, which I appreciate at least.

But git is simply being consistent with the shell to further reduce the cognitive complexity of reusing shell commands you're used to in analogous git contexts.

2 hours agompyne

- is a pretty standard idiom for using stdin/stdout instead of a named file that you can find in many commands. I don't think it conflicts with the cd/checkout usage though as there the argument normally does not refer to a file so having - mean stdin/stdout doesn't make sense.

A much larger base for ksh (as a pdksh descendent) is Android. OpenBSD is a tiny community in comparison, although Android has acquired code directly from OpenBSD, notably the C library.

The vi editing mode is always present in ksh, but is optional in dash. If present, the POSIX standard requires that "set -o vi" enable this mode, although other methods to enable it are not prohibited (such as inputrc for bash/readline), and as such is a "universal trick."

The article is relying on some Emacs mode, which is not POSIX.

$_ is not POSIX if I remember correctly.

History in vi mode is easier, just escape, then forward slash (or question mark) and the search term (regex?), then either "n" or "N" to search the direction or its reverse.

Ctrl-r works well at searching character trigrams, which can include space. Trigrams without space work well with auto_resume=substring .

`| sudo tee file` when current user does not have permission to >file

Another useful "Emergency exit" is CTRL+Z which stops the process and cannot be intercepted.

It's often faster than hitting CTRL+C and waiting for process cleanup, especially when many resources are used. Then you can do e.g. `kill -9 $(jobs -p)` to kill the stopped tasks.

All of the keyboard-driven terminal signals can be intercepted; catching INT (^C) for cleanup is just more common than the others. Only KILL and STOP cannot be caught.

^Z sends TSTP (not STOP, though they have the same default behavior) to suspend; some programs catch this to do terminal state cleanup before re-raising it to accept the suspension. Catching it to do full backout doesn't make as much sense because the program anticipates being resumed.

^\ sends QUIT, which normally causes a core dump and is rarely caught. If you have core dumps disabled (via ulimit -c 0 or other system configuration) then you can often use it as a harder version of ^C; this is how I would tend to get out of ‘sl’ in places where I found it unwantedly installed.

ctrl-z pauses the process, it doesn't terminate. I think of z as in zombie as you can then run fg to bring it back from paused state or as you suggested kill in it for good

Never heard of instant truncate, nor `fc`, nor `Esc .`

Quite a few useful ones

Is it just me, or is it an LLM language? The article tries very hard to be correct but somehow lacks experience.

I've never used the majority of these tricks for decades, except for brace expansion, process substitutions, and complex redirections.

4 hours agopiekvorst

I knew many of these tricks, but learned many new tricks I didn't know and looks very useful (like you can do Ctrl-Y after an Ctrl-U, the 'reset' or 'disown' thing).

Regarding experience, I'm also struck by how many "experienced" engineers are just clueless with the keyboard.

Close tab.

I ought to migrate away from shell scripting and just keep the shell for interactive use. Unfortunately I have cursed myself by getting competent-ish with P. shell and Bash scripting. Meaning I end up creating maintenance headaches for my future self.

(Echoes of future self: ... so I asked an LLM to migrate my shell scripts to Rust and)

Anyway with the interactive shell stuff. Yeah the I guess Readline features are great. And beyond that I can use the shortcut to open the current line in an editor and get that last mile of interactivity when I want it. I don’t really think I need more than that?

I tried Vim mode in Bash but there didn’t seem to be a mode indicator anywhere. So dropped that.

Edit: I just tested in my Starship.rs terminal: `set -o vi`. Then I got mode indicators. Just with a little lag.

My favourite shell trick is to comment my code:

  $ some_long_command -with -args -easily -forgotten # thatspecialthing
... Some weeks later ..

  $ CTRL-R<specialthing>
.. finds:

  $ some_long_command -with -args -easily -forgotten # thatspecialthing

Need to see all the special things you've done this week/whenever?

  $ history | grep "\#"
...

Makes for a definite return of sanity ..

I don’t keep history. Any commands I think will be useful, I save it in a script.

http://atuin.sh adds a database to store history in and a custom app to use for lookup with added modes to help with searching.

Yes indeed, it is very fun to discover this if you don't know it already, it expands your understanding of your shell life immensely, doesn't it?

What I hate is that if you start a command with a space it is not recorded in the history. This happens often when copy+pasting commands. I know you can turn it off but still ... this drives me mad.

AFAIK that setting is opt-in, at least in Bash.

Yeah but some operating systems have HISTIGNORE in (or sourced from) their skeleton files.

I just open, agent in tui, and ask it to do what I want and make a plan, i read the plan edit it and run it.

Simple, no need to learn any commandline these days.

I used to use arch and all, and managed many big projects. I find little value in learning new tools anymore, just feed it docs and it generated working plan most of the time

Now I've moved to coding in Haskell, which i find suits me better than wasting my time with cli and exploring what options all these cli tools have.

6 hours agofaangguyindia

I'm confused; how is writing a shell command (using shortcuts like those in the article!) "wasting time", but describing what you want to an LLM, having it make a plan, reading the plan, editing it, and running it is somehow not a waste of time?

You also mention there being "little value", when your proposed approach costs literal money in form of API/token usage (when using hosted models).

What is it like to be this proud of not learning the tools you use? Do you really think several paragraphs to an agent that may or may not be correct is the "easy" way compared to just checking the manual for the flag you want?

I will never understand people like you.
