I'm learning CentOS/RHEL and currently doing some stuff about process management.
The RHCSA book I'm reading describes running kill 1234
as sending SIGQUIT. I always thought the kill command without adding a switch for signal type should default to kill -15
SIGTERM is kill -15
and SIGKILL is kill -9
, right?
Does CentOS/RHEL use a slightly different method of kill -15
or have I just been mistaken?
EDIT: kill -l
gives SIGQUIT as kill -3
and it seems to be associated with using the keyboard to terminate a process. man 7 signal
also states that SIGQUIT is kill -3
, so I can only assume that my book is wrong in stating that SIGQUIT is kill -15
default.
