- alias name=value defines aliases, alias lists or shows them in a form
that can be read back, unalias removes them (unalias -a: all)
- the first word of every command (at the start and after ;, &, &&, ||
and |) is replaced, the value is expanded again except for aliases
that are already being expanded (alias ls='ls --color' works)
- a value ending with a blank makes the next word a command name too
- quoted or escaped words (\ll, 'll') skip the alias
- aliases are only expanded in interactive shells and their startup
files, like in bash
- tab completion includes aliases
