Re: [cobalt-users] what does this all mean ?

[Christopher Jay Manders <Chris.Manders@xxxxxxxxxxxxxxxx>]

Try 'man 7 signal' .. the man page is in the man7 section that contains all
the good explanations.

This man page describes all of the valid signals that can be sent to
processes. Good to know them if you use UNIX much. Note that they correspond
to numbers as well, so sending:
'killall -1 somepid' is the same as 'killall -HUP somepid', which sends the
SIGHUP signal to the process at somepid as seen in ps output.

SIGUSR1 is for a user defined signal. This tends to be used by processes that
are meant to run in user space, like web servers.  Thomas is completely
accurate in its behavior with httpd.

I hope this helps.
