# Systemd plugin
|
|
|
|
The systemd plugin provides many useful aliases for systemd.
|
|
|
|
To use it, add systemd to the plugins array of your zshrc file:
|
|
|
|
```zsh
|
|
plugins=(... systemd)
|
|
```
|
|
|
|

### User aliases
|
|
|
|
You can use the above aliases as `--user` by using the prefix `scu` instead of `sc`.
|
|
For example: `scu-list-units` will be aliased to `systemctl --user list-units`.
|
|
|
|
### Unit Status Prompt
|
|
|
|
You can add a token to your prompt in a similar way to the gitfast plugin. To add the token
|
|
to your prompt, drop `$(systemd_prompt_info [unit]...)` into your prompt (more than one unit
|
|
may be specified).
|
|
|
|
The plugin will add the following to your prompt for each `$unit`.
|
|
|
|
```text
|
|
<prefix><unit>:<active|notactive><suffix>
|
|
```
|
|
|
|
You can control these parts with the following variables:
|
|
|
|
- `<prefix>`: Set `$ZSH_THEME_SYSTEMD_PROMPT_PREFIX`.
|
|
|
|
- `<suffix>`: Set `$ZSH_THEME_SYSTEMD_PROMPT_SUFFIX`.
|
|
|
|
- `<unit>`: name passed as parameter to the function. If you want it to be in ALL CAPS,
|
|
you can set the variable `$ZSH_THEME_SYSTEMD_PROMPT_CAPS` to a non-empty string.
|
|
|
|
- `<active>`: shown if the systemd unit is active.
|
|
Set `$ZSH_THEME_SYSTEMD_PROMPT_ACTIVE`.
|
|
|
|
- `<notactive>`: shown if the systemd unit is *not* active.
|
|
Set `$ZSH_THEME_SYSTEMD_PROMPT_NOTACTIVE`.
|
|
|
|
For example, if your prompt contains `PROMPT='$(systemd_prompt_info dhcpd httpd)'` and you set the following variables:
|
|
|
|
```sh
|
|
ZSH_THEME_SYSTEMD_PROMPT_PREFIX="["
|
|
ZSH_THEME_SYSTEMD_PROMPT_SUFFIX="]"
|
|
ZSH_THEME_SYSTEMD_PROMPT_ACTIVE="+"
|
|
ZSH_THEME_SYSTEMD_PROMPT_NOTACTIVE="X"
|
|
ZSH_THEME_SYSTEMD_PROMPT_CAPS=1
|
|
```
|
|
|
|
If `dhcpd` is running, and `httpd` is not, then your prompt will look like this:
|
|
|
|
```text
|
|
[DHCPD: +][HTTPD: X]
|
|
```
