Signals - SIGHUP

[Manuales]

What are the signals?
i read the following file:
$ more /etc/envd.conf
# envd reads its configuration information when the envd daemon
# starts, and when it receives a SIGHUP signal to restart itself.

here talks about SIGHUP signal .. what does it mean and what other signals exist?

Hi Manuales:

SIGHUP is the 'hang-up' signal. Signals are give numbers and names with the prefix "SIG" for "signal". A 'kill -l' will list the various signals.

You should look at the manpages for 'kill(1)', 'kill(2)' and 'signal(5)' too.

By the way, you have additional responses to some of your questions last week to examine.

Regards!
