Linux

i love this person's work; i've been working in the linux sphere for over 20 years but this person always teaches something that's new to me and more helpful than the tools i've been using to get the job done; sed/awk in this case. (plus, the sense of humor also makes it fun to watch).

i wish i were as rich as my fellow software engineers so that i can support her work because i'm convinced we need it in a world where people no longer have the same opportunities i had to learn this kind of tech because their smartphones inadvertently hide needful knowledge in the abstractions that make smartphones work.

I doubt anyone has ever regretted spending some time familiarizing themselves with the POSIX, util-linux, and GNU coreutils commands. You can do a lot by just piping these (mostly) simple tools together.

Really cool tool

Her mentions of awk reminded me of a guy at my last job who was an absolute god with awk, but making changes to scripts he made were a nightmare because no one else could figure out what he was doing, and everything crashed and burned from small changes.

mount | column -t -s " "

Ahhhh...sanity. Thanks lovely Internet lady

Damn, I could've avoided hours of scrolling up by now if I knew about this before.

That's the first time i read about column....

cat /dev/hda1 | column | lolcat

This was a new one for me and I've been playing with linux for years. Also really enjoyed her video style so delved into some others.

Thanks for sharing!

Of yes, I have! alias nfsmounts='mount | grep "nfs" | column'

Yup, found it just the other day when I wanted to have ls -l output in multiple columns instead of a single one.

I have, but I also learned a few new things about column from this video, nice!

It's one of the few things that I think Powershell did more cleanly than Linux, was making those kind of options a lot clearer and pushing people to use them early on in education cycles, so knowledge of these cmdlets is more common than the Linux equivalents. (I know that's harder to do with an all-volunteer OS built from the ground up versus a private company influencing education cycles, obviously)

Format-Custom, Format-Hex, Format-List, Format-Table, and Format-Wide are pretty indispensable when working with Powershell.

Because precisely, 90% of the time, when it comes to Linux, the way you're taught is to just grep what you need out.

I've taken classes for both Powershell and Linux command line in college, and the PS class focused a lot on those commands while the Linux class never once mentioned column while spending a lot of time on grep.

column -s baby

When I first learned Unix (and then Linux) I just went through /usr/bin and looked at the man page for everything.

Then I browsed through the gnu info pages for bash.

There's no real alternative to RTFM.

I'm still sore that column -nts, doesn't work anymore. My mnemonic for remembering it was "unts, unts, unts" like a dance club beat.

Actually looking at the usage text I'm not sure how the -n flag ever worked for me... Maybe I'm misremembering.

Yeah but I keep trying to pipe the output back into the original file which ends up empty due to how pipe and redirect interact.
I know there must be a grown-up way to do it but I inevitably resort to writing it to filename2 and then running mv filename2 filename.

I learned to write scripts on Windows Powershell and got spoiled by everything being an object so when I started writing bash scripts I think 90% of the work is trying to parse the raw text output of commands with things like awk or sed.
