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.

# run a command for each result individually

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.

[–] [email protected] 21 points 7 months ago (1 children)

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

[–] [email protected] 13 points 7 months ago (2 children)

Then you dont know how the video is :D

[–] [email protected] 26 points 7 months ago

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

[–] [email protected] 9 points 7 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

[–] [email protected] 11 points 7 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...

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

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.

[–] [email protected] 1 points 7 months ago (1 children)

You're giving all your data to your VPN company, though

[–] [email protected] 1 points 7 months ago (1 children)

True. But I pay them via Monero

[–] [email protected] 1 points 7 months ago (1 children)

And give no personal information? Like Mullvad? That is an improvement.

[–] [email protected] 1 points 7 months ago* (last edited 7 months ago)

Yup. Also their VPN app on Linux is better than what KDE and GNOME have. Poorly. They hook into it very intensely, early boot blocking via a systemd service and all.

Her presentations are fun. Thanks! Great watch.

[–] [email protected] 6 points 7 months ago* (last edited 7 months ago)

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

[–] davetapley 5 points 7 months ago

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

I've never looked back.

[–] dohpaz42 4 points 7 months ago (2 children)

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

[–] [email protected] 3 points 7 months ago

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

[–] [email protected] 1 points 7 months ago (1 children)

Why?

[–] dohpaz42 1 points 7 months ago* (last edited 7 months ago)

Short answer: shell expansion.

Longer answer:

Executing a command for each file

• Run file on every file in or below the current directory.

$ find . -type f -exec file '{}' \;

Notice that the braces are enclosed in single quote marks to protect them from interpretation as shell script punctuation. The semicolon is similarly protected by the use of a backslash, though single quotes could have been used in that case also.

Thank you for the TL;dw. Sincerely appreciated.
