a quick linux tip

a quick linux tip

[Tyler Spivey]

well, i decided to contribute my .02 to here, here goes:
on most linux systems, maybe some other unix systems,
there is a command called reset.
if your terminal gets messed up (o echoing of commands, etc)
or wierd things appear (hard to explain, but really odd things instead of a shell prompt
for example), you can type reset at a shell prompt.
that usually fixes the problem if it's a terminal issue.
i don't know if this hapens on the linux console, but it happens to me on my serial terminal.

Hello,
talking of things going wrong, does any one know how to pass the exit
command to another console?  it would be a handy thing to know about...

Hi Darragh,

	You don't "pass the exit" to another console.

	Rather, do a:

	kill -9 PID

	where PID is the Process ID of the console (usually 'bash') process that you want to cause to "exit". You obtain the PID from the 'ps ax' commmand which will list PID's and lots of other info about all the processes runn
ing in your system.

HTH,

kill -1 also works.  I don't know all the implications of the kill
command and it's parameters however from what I've been told and what
I've seen, a -9 is usually the last resort of killing a process.  Some
can just take a plain sighup -1 in the case of a bash process it will
reset it and kill the console connection.  If you do a kill -1
pid_of_named it will re-read the named.conf configuration files like if
you add new zones.  If you want to kill a process that will not work
right with a -1 then -TERM -15 will do the trick.  And then if those
don't work I resort to a -9 to really force it to die.

Just my 2 cents worth.

You don't want to use kill on named, use rndc instead.

Hi Darragh,

How about using the ps command to locate the process for that console, then
using kill to get rid of it?

After doing reset, I also type "stty sane" to restore things to how they should be.
