From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

# find with grep

grep -r exists and is even more faster and doesn't require passing around file names.

grep -r --include='*.txt' 'somename' .

Or use strings if you want clean binary results. (Grep can probably do this, too)

Edit: Yes, with -b, also -R follows symlinks unlike -r

This does not need to be a 8 minute video. Read your tldw instead. Thanks, OP.

[–] Twitches@lemm.ee 20 points 6 months ago (1 children)

Better than the video thank you, I didn't watch the video

[–] boredsquirrel@slrpnk.net 15 points 6 months ago (2 children)

Then you dont know how the video is :D

[–] some_guy@lemmy.sdf.org 27 points 6 months ago (1 children)

Not the person above, but I know that written explanations of command line tools are always preferred by myself.

[–] eveninghere@beehaw.org 8 points 6 months ago

No, no, you just need to seek through the time and copy & paste the text in the video!

[–] Blizzard@lemmy.zip 9 points 6 months ago (1 children)

I know it's 8 minutes long.

Skip to 2:46 how she also mentioned in the description

Just for the sake of completeness:

https://github.com/BurntSushi/ripgrep

https://github.com/ggreer/the_silver_searcher

It's useful to be able to do this without additional tools (and there are more applications for the general command setup discussed in the video), but in practice, ease of use and performance often make a difference.

I have rg installed but only used it for basic grep replacement

[–] qjkxbmwvz@startrek.website 11 points 6 months ago

I kinda prefer xargs to the -exec option


just feels more UNIXy to me (do one one job well).

But as another comment said, for grep I just use -r and --include. So clearly I'm not very consistent...

Her presentations are fun. Thanks! Great watch.

[–] leadore@kbin.social 9 points 6 months ago (1 children)

I prefer to watch videos via peertube, not youtube, whenever possible. She has a peertube channel so here is the same video there: https://tinkerbetter.tube/w/g8K2zBgwwwE1xukkT6EmSo

[–] boredsquirrel@slrpnk.net 2 points 6 months ago

It is important to have backups for when Youtube blocks clients, but I just watch it over a VPN and Freetube or Grayjay. Not leeching any resources when avoidable, just costing big brother money.

If you have a very large directory, find will check each individual file, even when -path doesn't match, which makes it take longer to complete. Combine -o and -prune to omit them entirely.

find . -path '**/node_modules/**' -prune -o -type f -name '*.js' -exec grep 'import' {} +

She’s done such a good job with this channel. I understand most of the content, but I always pick up a nugget of new as well as being able to better explain after a topic she ELI5’d

[–] dohpaz42@lemmy.world 4 points 6 months ago (1 children)

When using both {} and ;, it’s safer to use single quotes to escape the current argument and ending delimiter; eg ’{}’ and ’;’, respectively.

[–] murtaza64@programming.dev 1 points 6 months ago

Why? The quotes will be consumed by the shell when you execute the command, unless you do like "'{}'"

[–] davetapley@lemmy.world 3 points 6 months ago

Forgive me for only TLDW and not watching, but was ack mentioned?

I've never looked back.

[–] ____@infosec.pub 2 points 6 months ago

Thank you for the TL;dw. Sincerely appreciated.
