In this article we will review sed, the well-known stream editor, and share 15 tips to use it in order to accomplish the goals mentioned earlier, and more.
Sort of tanslated from the first “via” (note that “mit Alles und Scharf” is hard to translate; it’s somewhere between “everything but the kitchen sink, but done right” and “right on the money”):
Bash Prompt Overkill: https://github.com/nojhan/liquidprompt is a Bash “Prompt doing it all right”-extension, which doesn’t care how much any feature costs as we have cores, gigabytes and SSD.
Liquid Prompt automagically recognises context and enables a plethora of features in the prompt when needed based on that context.
It’s like pixie dust for your prompt.
You can configure everything, but you don’t have to: the out of the box experience is already like pixie dust for your prompt.
It works on OS X too and is part of homebrew:
$ brew install liquidprompt

==> Caveats
Add the following lines to your bash or zsh config (e.g. ~/.bash_profile):
if [ -f /usr/local/share/liquidprompt ]; then
. /usr/local/share/liquidprompt
fi
If you'd like to reconfigure options, you may do so in ~/.liquidpromptrc.
A sample file you may copy and modify has been installed to
/usr/local/share/liquidpromptrc-dist
Don't modify the PROMPT_COMMAND variable elsewhere in your shell config;
that will break things.

As a Linux administrator you’ve got various tools to use in order to configure network connections, such as: nmtui, NetworkManager GUI and nmcli in Linux
This is so cool, but will take some time for lot’s of tooling to become compatible:
Starting with v197 systemd/udev will automatically assign predictable, stable network interface names for all local Ethernet, WLAN and WWAN interfaces. This is a departure from the traditional interface naming scheme (“eth0”, “eth1”, “wlan0”, …), but should fix real problems.
Not sure why without the -z compression switch this succeeds:
