So true. I think most of us who learned "advanced" bash is after being tired of feeling like an idiot looking at long bash scripts. Usually, those scripts are written by people who…

Nice one! I love those weird bash tricks. Some of the examples here are interesting, but they show parameter substitution more than colon itself: https://tldp.org/LDP/abs/html/para…

aha! I see what you mean, it's indeed a nice option, yep. Using brackets like this is something I never thought of, and it's probably why it's hard for me to process it, but I can …

That's very cool! To take advantage of the "leading space" one, I have this, to mark some commands that I never want to record: unhist () { alias $1=" $1" } unhist unhist unhist fz…

for multiline pipes, it's WAY better to format like foo | bar | baz You don't have to use backquotes, AND, it allows you to comment line by line, because there's no backslash messi…

A similar trick: #!/bin/sh $* that's my `~/bin/noglob` file, so when I call a zsh script from bash that uses `noglob`, it doesn't blow up.

I use a variant with ssh and some compression: docker save $image | bzip2 | ssh "$host" 'bunzip2 | docker load'

You can also nest those, so this way you can get a value from an argument, or an env var, and if none is set, error. echo "${1:-${env_var:?I need a value for that!}}"

Here's a solution in k, that uses a similar array oriented approach: &2=+/~x!/:\:x:!100 I wrote a little explanation of it, in case anyone is curious about how it works: https://gi…

I couldn't find a way to have more than one callback per signal, and created a system to have an array of callbacks: https://github.com/kidd/scripting-field-guide/blob/master/bo...…

Yep, good point. They are useful when you want to change the whole text inside the delimiters (and IME, it's most of the times), but they do different things than cf( because they …

I have 2 use cases for cf), but I don't use it a lot in the end: One is when inside a parenthesis, and wanting to really delete till the closing parenthesis. But that would leave a…

Another advantage of pipes at the end is that you can comment lines and the full pipeline still works. Some time ago I wrote a bunch of tips to make more ergonomic bash scripts: ht…

Here's where he explains how he did it: https://www.youtube.com/watch?v=ORjyXcLDd9M

Oh, I hadn't noticed that links are not highlighted as such (unless already visited). Fixed, thanks!

Fixed, thanks!

> If appropriate, change to the script’s directory close to the start of the script. > And it’s usually always appropriate. I wouldn't think so. You don't know where your script wi…

Oh! I didn't know that one could build an arbitrary string like that inside a map. Thanks a lot for that, I agree it looks better!

A very useful function in jq is "join", which I use a lot to cook the final shape of the data (many times used with fzf/dmenu) Here's a simple way to list and browse github issues …

Even funnier when you realize bash and zsh do different things (by default) there. foo="ls -las" $foo "$foo" for zsh to split words, `setopt SH_SPLIT_WORDS`.

Yep, sorry about that, I meant in general. This particular case is fine, and I am grateful for that.

yes! that looks super useful indeed. Thanks!

What I miss most about those collections is that they are browser based, and when I'm programming, if I need the music to stop, or I get a call, or something, I have to go find the…

thanks so much! I'll fix all those right away :+1:

wow, that's a great one!
