auto-editor for removing silent portions from video recordings

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!

Bobiverse by Dennis E. Taylor is a fun and easy read

+1 for Cradle already mentioned. I'd add

• The Riyria Revelations by Michael J. Sullivan
• Kings of the Wyld by Nicholas Eames

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

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$//' "$@" ; }

EPUB reader

Hope you find the book useful :)

I'd also suggest these shorter guides to get started:

• https://ferd.ca/awk-in-20-minutes.html
• https://backreference.org/2010/02/10/idiomatic-awk/
• https://earthly.dev/blog/awk-examples/

See also:

• tldr — collection of community-maintained help pages for command-line tools
• explainshell — write down a command-line to see the help text that matches each argument
• General purpose command-line tools — examples for most common usecases
• Bash reference cheatsheet — nicely formatted and explained well
• Bash scripting cheatsheet — quick reference to getting started with Bash scripting

If you don't mind sci-fi: Red Rising by Pierce Brown

And there's the classic The Count of Monte Cristo by Alexandre Dumas

I start my search string with stackoverflow as a workaround.

Yeah, PCC is a good choice. Make sure to type examples codes manually (i.e. don't just read them) and try to solve all the exercises. Since you mention you want to learn it as a hobby, "Automate the Boring Stuff with Python" (2nd edition) would be a good choice as well, as you might find some of the projects in the second half helpful.
