# find with grep
# + concatinates results and runs the command once, faster
find . -name "*.txt" -exec grep -l "somename" '{}' '+'
# run a command for each result individually
find . -name "*.txt" -exec basename '{}' \';' | column
# case insensitive
find -iname "SoMeNaMe.TxT
# file or dir

grep -rexists and is even more faster and doesn’t require passing around file names.grep -r --include='*.txt' 'somename' .Or use
stringsif you want clean binary results. (Grep can probably do this, too)Edit: Yes, with
-b, also-Rfollows symlinks unlike-r
This does not need to be a 8 minute video. Read your tldw instead. Thanks, OP.
Better than the video thank you, I didn’t watch the video
Then you dont know how the video is :D
Not the person above, but I know that written explanations of command line tools are always preferred by myself.
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
I kinda prefer
xargsto the-execoption — just feels more UNIXy to me (do one one job well).But as another comment said, for
grepI just use-rand--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.
You’re giving all your data to your VPN company, though
True. But I pay them via Monero
And give no personal information? Like Mullvad? That is an improvement.
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.
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
If you have a very large directory, find will check each individual file, even when
-pathdoesn’t match, which makes it take longer to complete. Combine-oand-pruneto omit them entirely.find . -path '**/node_modules/**' -prune -o -type f -name '*.js' -exec grep 'import' {} +When using both
{}and;, it’s safer to use single quotes to escape the current argument and ending delimiter; eg’{}’and’;’, respectively.Why? The quotes will be consumed by the shell when you execute the command, unless you do like
"'{}'"Why?
Short answer: shell expansion.
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.
