Shell Script to find out if a process is running on any all machines
Hi All, I have been a guest visitor from a long time and this forum is wonderful. I finally am a member of this forum too, so i am here stuck with a shell script that i was trying to write
My requirement is that i should be able to create a shell script which will check if a process is running on this machine and any other machines too i.e if i am trying to start a app on server3 it should first check if the app is already started on server1 and server2 if not then it should start this app on server3 else it should exit.
I tried using the script to create lock file to do the same but was not sure if that would, for an idea i will post that script here. please help me out guys, thank you!!!

Hi All,
The scenario is like this:
There is a process say "A" which create a child process say "B" if some condition is true and process "A" terminates. "B" invokes some C program say "C" using 'execl' function. The job of program "C" is to keep polling the server until the server will be up.... (2 Replies)
I want to write a unix shell script that will check if a process (say debu) is running in the server or not. If no , then send a mail to the corresponding person to start the process??? (2 Replies)
OS: Unix or Linux
I (only) know the pid of the process which was running earlier (say 5 hrs back) but it is not running now.
Is there a way I could find the details of that process? (atleast the name of the process). Please let me know. (2 Replies)
Hello all,
I would be happy if any one could help me with a shell script that would determine all the processes running on a Unix server and post a mail if any of the process is not running or aborted.
Thanks in advance

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/.
