Cuando me preguntan cómo me aprendí tanto comando en la terminal:

When you're using ${cmd} to get the output of the command instead of $(cmd).

A bash surprise: https://www.gnu.org/software/bash/manual/html_node/Shell-Functions.html says:

Functions are declared using this syntax:

fname () compound-command [ redirections ]

Usually curly braces are used for the compound command. Yet parentheses work too. And those go into a sub-shell. Run this and carefully inspect the output.

function fun() ( # parenthesis!
echo hallo
echo fun has $$ $BASHPID
)
fun
echo main has $$ $BASHPID

By using () in a function definition, we force it into a subshell.

Im eigenen Git Repository hat sich was verändert (meistens ein Update) Schau dir an was genau!

Das kurze Bash-Skript veröffentlicht das Ergebnis auf Github Gist und setzt einen Trött mit einem Link dahin ab

Das Script kann sehr einfach an eigene Repos angepasst werden.

When you want to rerun a shell command you ran some time ago, how do you usually search for it?

Random useful linux CLI thing I just learnt.

If you don't want to see all that lengthy text after sshing to a machine, just do

touch ~/.hushlogin

(This command creates an empty file ".hushlogin" in your user home directory)

on the machine you are sshing to. Now there won't be any welcome messages to clutter your terminal, just a prompt.

Today I (re)learned there be three ways for `date` to number weeks;

- `%U` week number of year, with Sunday as first day of week (00..53)
- `%V` ISO week number, with Monday as first day of week (01..53)
- `%W` week number of year, with Monday as first day of week (00..53)

What if bash was written in Rust? I think it's time.
