UNIX for Dummies Questions & Answers

I got these results.

Code:

   PID TTY         TIME CMD
  8535 pts/24      0:00 ksh
  8528 ?           0:00 sshd
  7949 pts/23      0:00 ksh
  7878 ?           0:00 sshd

I've got two sessions running - is that the ksh entries?
I have one background job running that I submitted # 7435 - that' the number that the log shows me in nohup.out. I can't even see that in the list???? I type jobs 7435 and it says no such job.
What are the sshd jobs shown?
Would this be/result from sudo su command I entered?
What can I type to get more details on the two sshd jobs?

I have no Unix training so I hope you'll forgive my newbie - ness

You're logging in with ssh, right? That's what the sshd jobs are there for -- they're the processes that handle the network talk.

The ksh processes are the shells for each of your sessions.

Try 'ps pid' to see if your nohup-ed process is actually still running.

What more details do you want on the sshd jobs?

the 'sudo su' command would show up under a different user than you, since that's what sudo and su are used for.

The jobs command is built into the shell. It optionally takes as an argument the job number that the shell assigned to the command; not the PID. The job number is presented by the shell when you add an & suffix to any command:

Code:

$ nohup t16 >x 2>&1 &
[1]     16217

Depending on the shell, if you want to query the job information for job 1, the command would be:

Code:

jobs %1     # kshell
jobs 1         #bash

I think bash might also accept %1, but Im not sure. Regardless, issuing the jobs command without any parameters will show you all of the commands that the shell is running asynchronously.
