This creates distinct tutorial examples from complex feature examples (more how-tos). Both sets are getting builder / derive versions (at least the critical ones).

[`pacman`](https://wiki.archlinux.org/index.php/pacman) defines subcommands via flags.
|
|
|
|
Here, `-S` is a short flag subcommand:
|
|
```bash
|
|
$ pacman -S package
|
|
Installing package...
|
|
```
|
|
|
|
Here `--sync` is a long flag subcommand:
|
|
```bash
|
|
$ pacman --sync package
|
|
Installing package...
|
|
```
|
|
|
|
Now the short flag subcommand (`-S`) with a long flag:
|
|
```bash
|
|
$ pacman -S --search name
|
|
Searching for name...
|
|
```
|
|
|
|
And the various forms of short flags that work:
|
|
```
|
|
$ pacman -S -s name
|
|
Searching for name...
|
|
$ pacman -Ss name
|
|
Searching for name...
|
|
```
|
|
*(users can "stack" short subcommands with short flags or with other short flag subcommands)*
|
|
|
|
**NOTE:** Keep in mind that subcommands, flags, and long flags are *case sensitive*: `-Q` and `-q` are different flags/subcommands. For example, you can have both `-Q` subcommand and `-q` flag, and they will be properly disambiguated.

Let's make a quick program to illustrate.
