Hey I have homework and Im trying real hard to be friends with Linux. I am trying! Im using Fedora 8

First I just want to say that it always seems like i cant get commands typed properly so that they work --even if i consult the man pages and do what they say.

In this situation, I am trying to restart the rsyslogd daemon because I have modified the rsyslog.conf file so that I can get lpr.debug messages. So how do I restart rsyslogd? I looked in the man pages and it says the signal is SIGHUP and I tried that but it doesnt work.

Here is what Ive tried and the results:

So i dont know what Im doing wrong. I love the man pages because they are always a quick answer, except I never use it right.

please help

If you checked the LQ Rules you'd have seen LQ doesn't deal with homework. So if you have stuff you should learn by experimenting yourself then by asking for handouts you won't learn a thing. Running 'kill -l' gives you the signal names. Chop off the "SIG" part. Then

Im not asking for handouts you retard. I had been sitting here working and reading like a monster but thins still werent working. I ask questions here all the time, some for homework, some not, either way I always learn something new from the answers which help me learn even more.

I think you just wanted to say that to feel cool or something.

btw, thanks for the help; I already tried the HUP thing but it seemed like it didnt work. Plus, how come the man pages say SIGHUP instead of HUP ?? It doesnt tell me how to type it in or im not reading it correctly.

That doesnt seem to work either.
[root@localhost etc]# kill -HUP 'cat /var/run/rsyslogd.pid'
bash: kill: cat /var/run/rsyslogd.pid: arguments must be process or job IDs

what am I failing to understand?

Backticks vs single quotes? This notation should be easier to understand: 'kill -HUP $(cat /var/run/rsyslogd.pid)'

Yeah that worked. I just dont understand why the man page says SIGHUP. It doesnt say to do -HUP

Im new and still learning a lot of basic stuff.. sorry

It's the same. kill -sighup should also work. I guess you were confused by the backticks. Can you confirm that

'kill -SIGHUP $(cat /var/run/rsyslogd.pid)'

works for you, too?

You are requested to mind your manners, not post homework questions and show proper respect for your fellow LQ members.

Again, I was not asking for a direct handout on my homework. I was doing my homework and along the way I encountered a problem that prevented me from finishing my homework. All I asked was how to restart the rsyslogd because my commands werent working. I almost had it but of course the commands were all different than what I was told by the man pages and other research.

Its not like I was asking for someone to do my homework, and I thought that was clear enough. Next time I wont use the hot-word "homework" in order to avoid distractions from the topic.

Oh and sorry if I hurt that guys feelings. :'(

Hi,

I guess you have overlooked my question (2 posts before your reply). I'd really appreciate if you could answer it

Thanks,
Rainer

Signals are defined in the libs as SIG<name> eg SIGHUP.
however, when you wnat to manually send a signal to a process, you use the short versio ie sans 'SIG' eg

kill -HUP <pid>

where you substitute the process id for <pid>.
'kill' in fact just sends the requested signal (or TERM). See http://linux.die.net/man/1/kill

aha, I knew that I always screw up the command line. For me -SIGHUP also worked (on Fedora 8). But -HUP seems to be the safe bet. Thanks for pointing out.

In fact they are symbolic names so you could use the number instead, but names are easier.
