Regex syntax and features vary between implementations. \d isn’t supported by BRE/ERE flavors.
GNU grep supports PCRE, so you can use grep -oP '/dev/loop\d' or grep -o '/dev/loop[0-9]' if you are matching only one digit character.


Thanks a lot for the feedback :)


Well, I’m not going to even try understanding the various features used in that sed command. I do know how to use basic loops with labels, but I never bothered with all the buffer manipulation stuff. I’d rather use awk/perl/python for those cases.


This might work, but I think it is best to not tinker further if you already have a working script (especially one that you understand and can modify further if needed).
perl -pe 's/\[[^]]+\]\((?!https?)[^#]*#\K[^)]+(?=\))/lc $&=~s:%20|\d\K\.(?=\d):-:gr/ge'


Hmm, OP mentioned “Only edit what’s between parentheses” - don’t see anywhere that whole URL shouldn’t be changed…


Here’s a solution with perl (assuming you don’t want to change http/https after the start of ( instead of start of a line):
perl -pe 's/\[[^]]+\]\(\K(?!https?)[^)]+(?=\))/lc $&=~s|%20|-|gr/ge' ip.txt
e flag allows you to use Perl code in the substitution portion.\[[^]]+\]\(\K match square brackets and use \K to mark the start of matching portion (text before that won’t be part of $&)(?!https?) don’t match if http or https is found[^)]+(?=\)) match non ) characters and assert that ) is present after those characters$&=~s|%20|-|gr change %20 to - for the matching portion found, the r flag is used to return the modified string instead of change $& itselflc is a function to change text to lowercase

Check out my chapter on GNU grep BRE/ERE for those wanting to learn this regex flavor: https://learnbyexample.github.io/learn_gnugrep_ripgrep/breere-regular-expressions.html (there’s also another chapter for PCRE)
I use Vim ;)
Python itself provides IDLE, which is good enough for beginners. https://thonny.org/ is another good one for beginners.
As mentioned by others, Jetbrains is good for many languages. https://www.kdevelop.org/ is another option.
I have a list of learning resources for CLI tools and scripting here: https://learnbyexample.github.io/curated_resources/linux_cli_scripting.html
I’ve also written a few TUI interactive apps to practice text processing commands like grep, sed, awk, coreutils, etc: https://github.com/learnbyexample/TUI-apps
I started reading progression fantasy on Royal Road earlier this year (a site for posting web serials). Here’s my current follow list (excluding stories that are on hiatus):
oxipng, pngquant and svgcleaner for optimizing images
auto-editor for removing silent portions from video recordings

I’m not familiar with such softwares (I use pandoc for technical writing), but might help you…


Yeah, it is uncommon spelling, but if you google, you’ll find it’s not that rare ;)


I had to learn Linux CLI tools, Vim and Perl at my very first job. Have a soft spot for Perl, despite not using it much these days other than occasional one-liners (mainly for advanced regex features).


Thanks! 😊
