sed -n 2p file

    sed -n 2,4p file

There also some very niche stuff that I won't use but found funny

What's always interesting to me is how many of these I'll see and initially think, "I don't really need that." Because I'm well aware of the effect (which I'm sure has a name - I suppose it's similar to induced demand) of "make $uncommon_task much cheaper" -> "$uncommon_task becomes the basis of an entirely new workflow/skill". So I'm going to try out most of them and see what sticks!

Also: really love the style of the post. It's very clear but also includes super valuable information about how often the author actually uses each script, to get a sense ahead of time for which ones are more likely to trigger the effect described above.

A final aside about my own workflows which betrays my origins... for some of these operations and for others i occasionally need, I'll just open a browser dev tools window and use JS to do it, for example lowercasing a string :)

A password or token generator, simple or complicated random text.

Scripts to list, view and delete mail messages inside POP3 servers

n, to start Nautilus from terminal in the current directory.

lastpdf, to open the last file I printed as PDF.

lastdownload, to view the names of the n most recent files in the Downloads directory.

And many more but those are the ones that I use often and I remember without looking at ~/bin

- When I was a fresh engineer I used a pretty vanilla shell environment

- When I got a year or two of experience, I wrote tons of scripts and bash aliases and had a 1k+ line .bashrc the same as OP

- Now, as a more tenured engineer (15 years of experience), I basically just want a vanilla shell with zero distractions, aliases or scripts and use native UNIX implementations. If it's more complicated than that, I'll code it in Python or Go.

sed, awk, grep, and xargs along with standard utilities get you a long long way.

Otherwise, I am happy to be pulled into your discussion, Marshall McLuhan style[3] to adjudicate, for a very reasonable fee.

The way you’re doing it trashes files sequentially, meaning you hear the trashing sound once per file and ⌘Z in the Finder will only restore the last one. You can improve that (I did it for years) but consider just using the `trash` commands which ships with macOS. Doesn’t use the Finder, so no sound and no ⌘Z, but it’s fast, official, and still allows “Put Back”.

> jsonformat takes JSON at stdin and pretty-prints it to stdout.

Why prioritise node instead of jq? The latter is considerably less code and even comes preinstalled with macOS, now.

> uuid prints a v4 UUID. I use this about once a month.

Any reason to not simply use `uuidgen`, which ships with macOS and likely your Linux distro?

Like, it's okay -- even good -- for the tools to bend to the user and not the other way around.

I have almost the same, but differently named with scratch(day), copy(xc), markdown quote(blockquote), murder, waitfor, tryna, etc.

I used to use telegram-send with a custom notification sounnd a lot for notifications from long-running scripts if I walked away from the laptop.

I used to have one called timespeak that would speak the time to me every hour or half hour.

I have go_clone that clones a repo into GOPATH which I use for organising even non-go projects long after putting go projects in GOPATH stopped being needed.

I liked writing one-offs, and I don't think it's premature optimization because I kept getting faster at it.

You can configure your shell to notify the terminal of directory changes, and then use your terminal’s “open new window” function (eg: ctrl+shift+n) to open a new window retaining the current directory.

^ (jump to the beginning)

ctrl+v (block selection)

j (move cursor down)

shift+i (bulk insert?)

type ><space>

ESC

I use this as a bookmarklet to grab the front page of the new york times (print edition). (You can also go back to any date up to like 2011)

I think they go out at like 4 am. So, day-of, note that it will fail if you're in that window before publishing.

    javascript:(()=>{let d=new Date(new Date().toLocaleString('en-US',{timeZone:'America/New_York'})),y=d.getFullYear(),m=('0'+(d.getMonth()+1)).slice(-2),g=('0'+d.getDate()).slice(-2);location.href=`https://static01.nyt.com/images/${y}/${m}/${g}/nytfrontpage/scan.pdf`})()

Anyways, my favourite alias that I use all the time is this:

    alias a='nvim ~/.zshrc && . ~/.zshrc'

  #!/bin/sh
  if test "$#" != 2
  then
      echo 'Error: unmv must have exactly 2 arguments'
      exit 1
  fi
  exec mv "$2" "$1"

I genuinely wonder, why would anyone want to use this, often?

alias ..='cd ..'

alias ...='cd ../..'

alias ....='cd ../../..'

alias .....='cd ../../../..'

alias ......='cd ../../../../..'

alias .......='cd ../../../../../..'

And you can type `rn -rf *` to see all timezones recursively. :)
