[Bug 1742410] [NEW] service --status-all takes too long

[OwN]

Public bug reported:

The command:

service --status-all

Takes too long to iterate through all of the services.  There should be
a faster way (perhaps a --quick flag that doesn't actually check the
status of the service, but just output its name) to search services.
With Ubuntu 14.04 and Ubuntu 16.04 using different service names for
php-fpm (php5-fpm in Ubuntu 14.04 and php7.0-fpm in Ubuntu 16.04),
developers supporting multiple platforms need to be able to determine
the service name.

If I run the below command on a slower computer:

service --status-all 2>&1 | grep -F -- "-fpm" | awk '{print $4}'

It takes several seconds (up to 5 seconds) to return "php7.0-fpm".

That, or I think we should be able to do something like this

service --status-all fpm

In which the listed services only include services that contain the
characters "fpm" in them.

Developers that have to interact with these services need a faster way
to determine the name of the service since they continually change from
one OS version to another.
