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

Why do you think it is a phishing link? Gumroad is a well known platform to sell digital goods.

I mention it is free up to some date because it will go back to being a paid product after that.

Not my blog, just sharing it here.

That said, I don’t see that broken rectangle on Chromium.

Is it regex or sed/awk syntax (or both) that gives you trouble?

I had similar reaction and didn’t even try to learn them for years - then I caught the stackoverflow craze of answering CLI questions (and learning from others).

oxipng, pngquant and svgcleaner for optimizing images

auto-editor for removing silent portions from video recordings

Not my blog, just sharing it here. Saw it on HN (https://news.ycombinator.com/item?id=40419325)

What’s the difference between two_percent and skim?

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 ;)

You’re welcome, happy learning :)

I’m self-published and haven’t worked for other publications. Sometimes, my submissions reach HN front page, so you might have seen there or because others picked it up from there and shared around elsewhere.

As per the manual, “Mappings are set up to work like most click-and-type editors” - which is best suited with GUI Vim.

While Vim doesn’t make sense to use without the modes, there are plugins like https://github.com/tombh/novim-mode!

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 a lot for the kind words! Means a lot to me :)

Thanks! 😊

That’s great to hear and thanks for the kind feedback :)

I use GitHub pages and mdbook (https://github.com/rust-lang/mdBook)

I used to use it for posting on Twitter, with some keywords (like book title) in bold.

alias a='alias'

a c='clear'
a p='pwd'
a e='exit'
a q='exit'

a h='history | tail -n20'
# turn off history, use 'set -o history' to turn it on again
a so='set +o history'

a b1='cd ../'
a b2='cd ../../'
a b3='cd ../../../'
a b4='cd ../../../../'
a b5='cd ../../../../../'

a ls='ls --color=auto'
a l='ls -ltrhG'
a la='l -A'
a vi='gvim'
a grep='grep --color=auto'

# open and source aliases
a oa='vi ~/.bash_aliases'
a sa='source ~/.bash_aliases'

# sort file/directory sizes in current directory in human readable format
a s='du -sh -- * | sort -h'

# save last command from history to a file
# tip, add a comment to end of command before saving, ex: ls --color=auto # colored ls output
a sl='fc -ln -1 | sed "s/^\s*//" >> ~/.saved_commands.txt'
# short-cut to grep that file
a slg='< ~/.saved_commands.txt grep'

# change ascii alphabets to unicode bold characters
a ascii2bold="perl -Mopen=locale -Mutf8 -pe 'tr/a-zA-Z/𝗮-𝘇𝗔-𝗭/'"

### functions
# 'command help' for command name and single option - ex: ch ls -A
# see https://github.com/learnbyexample/command_help for a better script version
ch() { whatis $1; man $1 | sed -n "/^\s*$2/,/^$/p" ; }

# add path to filename(s)
# usage: ap file1 file2 etc
ap() { for f in "$@"; do echo "$PWD/$f"; done; }

# simple case-insensitive file search based on name
# usage: fs name
# remove '-type f' if you want to match directories as well
fs() { find -type f -iname '*'"$1"'*' ; }

# open files with default application, don't print output/error messages
# useful for opening docs, pdfs, images, etc from command line
o() { xdg-open "$@" &> /dev/null ; }

# if unix2dos and dos2unix commands aren't available by default
unix2dos() { sed -i 's/$/\r/' "$@" ; }
dos2unix() { sed -i 's/\r$//' "$@" ; }
