I have a script that conducts some SSH calls and I would like to capture the child info so that I can do a sleep and then a cleanup to make sure they do not stay out there as ghosts.
I was told I could do something like this...
But thats not working. I am not a really good at this yet.
I want to catch the PIDS or whatever I need so that after a sleep of say... 300 I could then tell the script to go kill all the PIDS that were started to make sure they finished.
Could somebody help me out here with it?
Thanks

I just need to find a way to have the script compile a list of all the PIDS created from doing the SSH calls so it can then go through at the end to check that they all ended and if not kill them.
Like the topic says, does anyone know if it is possible to check to see when an FTP only user has logged in? Because the shell is /bin/false and they are only using FTP to access the system doing a "finger" or "last" it says they have never logged in.
Is there a way to see when ftp users log in... (1 Reply)
Hi,
There is a file having a list of running PIDs and another file having a list of registered PIDs. How can we check if the number of running PIDs are less or more than the registered PIDs, comparing the total no. in each and also each value.
Request you to pls give your inputs.
Thanks a... (2 Replies)
Hello,
I am trying to write a script that turns off the screensaver for a certain period of time, then come back on. I have had it up and running for a while, but then I decided to refactor it a bit for my family members that are less computer savvy.
I am starting a subshell for the "meat" of... (4 Replies)
Hey,
So I'm new to shell scripting, and I'm trying to write one for my lab that will keep down the work load by deleting processes that are left over from previous sessions.
Basically I want it to do three things.
1) Check the processes running
2) See if that person is logged on.
3) if... (2 Replies)

Hi there !!!

Good afternoon
I need to KILL a process in a single command sentence, for example:
kill -9 `ps -aef | grep 'CAL255.4ge' | grep -v grep | awk '{print $2}'`
That sentence Kills the process ID corresponding to the program CAL255.4ge.
However it is possible that the same program... (6 Replies)
im looking for a portable way to get the PID of the script that is running, and to get every other PIDs that are spawned from it.
and by ever other PIDs, i presume, that would be "child processes".

script
SCRIPT(1) BSD General Commands Manual SCRIPT(1)NAME
script -- make typescript of terminal session
SYNOPSIS
script [-a] [-c COMMAND] [-e] [-f] [-q] [-t] [file]
DESCRIPTION
Script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
Options:
-a Append the output to file or typescript, retaining the prior contents.
-c COMMAND
Run the COMMAND rather than an interactive shell. This makes it easy for a script to capture the output of a program that behaves
differently when its stdout is not a tty.
-e Return the exit code of the child process. Uses the same format as bash termination on signal termination exit code is 128+n.
-f Flush output after each write. This is nice for telecooperation: One person does `mkfifo foo; script -f foo' and another can super-
vise real-time what is being done using `cat foo'.
-q Be quiet.
-t Output timing data to standard error. This data contains two fields, separated by a space. The first field indicates how much time
elapsed since the previous output. The second field indicates how many characters were output this time. This information can be used
to replay typescripts with realistic typing and output delays.
The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. Script works best with commands that do not manipulate
the screen, the results are meant to emulate a hardcopy terminal.
ENVIRONMENT
The following environment variable is utilized by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
shells set this variable automatically).
SEE ALSO csh(1) (for the history mechanism), scriptreplay(1).
HISTORY
The script command appeared in 3.0BSD.
BUGS
Script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
AVAILABILITY
The script command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
