- Completion of filenames, even on strings with wildcards such as '`*`', '`**`' and '`?`'.
- Completion of job ID, job name and process names for <a href="#expand-process">process expansion</a>.
`fish` provides a large number of program specific completions. Most of these completions are simple options like the `-l` option for `ls`, but some are more advanced. The latter include:
- The programs `man` and `whatis` show all installed manual pages as completions.

The `~` (tilde) character at the beginning of a parameter, followed by a username, is expanded into the home directory of the specified user. A lone `~`, or a `~` followed by a slash, is expanded into the home directory of the process owner.
\subsection expand-process Process expansion
The `%` (percent) character at the beginning of a parameter followed by a string is expanded into a process ID (PID). The following expansions are performed:
- If the string is the entire word `self`, the shell's PID is the result.
- Otherwise, if the string is the entire word `last`, the last job's PID is the result.
- Otherwise, if the string is the ID of a job, the result is the process group ID of the job.
- Otherwise, if any child processes match the specified string, their PIDs are the result of the expansion.
- Otherwise, if any processes owned by the user match the specified string, their PIDs are the result of the expansion.
- If none of these matches apply, an error is produced.
This form of expansion is useful for commands like kill and fg, which take process IDs as arguments.
Example:
`fg %%ema` will search for a process whose command line begins with the letters 'ema', such as emacs, and if found, put it in the foreground.
`kill -s SIGINT %3` will send the SIGINT signal to the job with job ID 3.
\subsection combine Combining different expansions
All of the above expansions can be combined. If several expansions result in more than one parameter, all possible combinations are created.

If you want to run a set of commands when `fish` exits, use an <a href='#event'>event handler</a> that is triggered by the exit of the shell:
\fish
function on_exit --on-process %self
function on_exit --on-process $fish_pid
echo fish is now exiting
end
