```zsh
plugins=(... common-aliases)
```

## Global aliases

These aliases are expanded in any position in the command line, meaning you can use them even at the
end of the command you've typed. Examples:

Quickly pipe to less:
```zsh
$ ls -l /var/log L
# will run
$ ls -l /var/log | less
```
Silences stderr output:
```zsh
$ find . -type f NE
# will run
$ find . -type f 2>/dev/null
```

## File extension aliases

These are special aliases that are triggered when a file name is passed as the command. For example,
if the pdf file extension is aliased to `acroread` (a popular Linux pdf reader), when running `file.pdf`
that file will be open with `acroread`.

| chm   | `xchm`      | Opens up a .chm file using xchm     |
