🚀 Wow! One command to save the world from overpriced MCP manuals! 📚 Turns out, we just needed a smartypants to swap a JSON dump for some good ol' CLI magic. Next time, let's try turning water into wine! 🍷🎩✨

Tired of all these "Yes"-Sayers all the time?:

```.bashrc
no() {yes no}
maybe() { a=(no yes); while :; do echo "${a[$((RANDOM % 100 < ${1:-50}))]}"; done; }
```

#TIL: #xargs has an option -a to read items from a file instead of from standard input. This is perfect if you need to run xargs without a surrounding shell to provide the commonly used pipe mechanism, e.g. calling it just via exec() or similar.

My case today was with Perl's Test::Command::Simple::run_ok() in pxzgrep's TAP based test suite.

#TIL: Filter in #htop (either via pressing F4 or via the commandline option "-F") can't do regular expressions, but the pipe character "|" can be used to separate multiple search terms. E.g. only showing processes which have `systemd` or `sd-pam` in their name works like this:

htop -F 'systemd|sd-pam'

(Bash) One liner to create a QR-Code to connect your phone to the Wifi your PC is connected to using nmcli, qrencode and bash...
sudo bash -c 'CON=$(nmcli -t c s | grep -m 1 '802-11-wireless' | cut -d ":" -f 1) && SSID=$(nmcli -t c s $CON | grep '\.ssid:' | cut -d ":" -f 2) && PSK=$(nmcli -t -s c s $CON | grep '\.psk:' | cut -d ":" -f 2) && echo "SSID=>$SSID< PSK=>$PSK<" && qrencode -t ansiutf8 -s 10 "WIFI:T:WPA2;S:$SSID;H:false;P:$PSK;;"'

(edit: slightly improved)

CLI makes many things just way more efficient.

The problem: find all emails sent by any of 60 students since August to make sure I've not forgotten anything agreed. I have email addresses in a text file

Solution:

xargs -I M notmuch search date:2023-08-01.. from:M < emails.txt

Not sure if any of GUI email clients can perform similar operation as easily.

Shortest PATH possible. Removes duplicates and merged directories (/bin -> /usr/bin). Don't use if your PATH happens to contain ':'

export PATH=$(echo $PATH | tr ':' '\n\r' | xargs readlink -f | sort -u | tr '\n\r' ':')
