Show domain in steeef.zsh-theme #3

Closed 2Belette closed 3 months ago

2Belette commented 3 years ago

Would it be possible to do a quick hack to display domain after the host on steeef theme ? I like this theme so much, but I have multiple VM with the same name bur on different domain, so I got the same result when I connect to them :

user at host in /home/....#

I would like to append the domain to show user at host.domain1 in /home/....# user at host.domain2 in /home/....#

I know how to do that manually but would it be possible to retrieve it from resolv.conf for example ?

I would like to avoid extra ms to display / parse and more importantly not sending anything to the network.

If you have any suggestions :)

Hi @2Belette. In steeef.zsh-theme, replace %m by %2m two have 2 components displayed (or replace by the number you prefer), or by %M to have the full machine hostname displayed.

See more at the Prompt-Expansion documentation.

Thanks @ericbn ! I learned something :) For my usecase it doesn't work as my machine has short name in hostname and I would need to find a way to append the domain name but I can't find a way. Is there a way to parse anything? like echoing something

Doesn't %M work?

2Belette commented 3 years ago

@lnicola it is giving me the same result as %m

for example : username : belette name of the computer : x1 domain name on resolv.conf (mydomain.com)

zim prompt with %m :belette at x1 in ~$ zim prompt with %M : belette at x1 in ~$

No difference

Note that the domain (called search now) line in resolv.conf doesn't set the domain name of your current computer, but configures the DNS resolver. The FQDN is in /etc/hostname (or you can check it with hostnamectl if you're running systemd).

I think you can also embed commands in the prompt (PS1='$(ls)'), but reading that file on each prompt would be quite slow. I would rather make sure the domain is configured correctly instead.
