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.

What is your most useful Linux app which others might not know about (please don't just give the name but a link and why it is good for you) ? (feddit.org)

Why software do you use in your day-to-day computing which might not be well-known?

For me, there are ~~two~~ three things for personal information management:

for shopping receipts, notes and such, I write them down using vim on a small Gemini PDA with a keyboard. I transfer them via scp to a Raspberry Pi home server on from there to my main PC. Because it runs on Sailfish OS, it also runs calendar (via CalDav) and mail nicely - and without any FAANG server.
for things like manuals and stuff that is needed every few months ("what was just the number of our gas meter?" "what is the process to clean the dishwasher?") , I have a Gollum Wiki which I have running on my Laptop and the home Raspi server. This is a very simple web wiki which supports several markup languages (like Markdown, MediaWiki, reStructuredText, and Creole), and stores them via git. For me, it is perfect to organize personal information around the home.
for work, I use Zim wiki. It is very nice for collecting and organizing snippets of information.
oh, and I love Inkscape(a powerful vector drawing program), Xournal (a program you can write with a tablet on and annotate PDFs), and Shotwell (a simple photo manager). The great thing about Shotwell is that it supports nicely to filter your photos by quality - and doing that again and again with a critical eye makes you a better photographer.

GNU parallel, to run commands on all cores, and for its filename pattern substitution.

For example: ls *.flac | parallel ffmpeg -i {} {.}.mp3 encodes a directory of FLAC files to MP3. parallel -a <(ls *.flac) -a <(ls *.mp3) --xapply copytags {1} {2} then copies each FLAC file's metadata to the corresponding MP3 file (which ffmpeg already does, just to illustrate the --xapply option).

edit: copytags is https://github.com/DarwinAwardWinner/copytags if that's useful for anyone.

Parallel is great!

Alternatively your second command can be written as: parallel "copytags {1} {2}" ::: *.flac :::+ *.mp3.

Also it is nice to exec commands on multiple devices.
