script for failed processes
I want to write a script that log all the failed processes and start the same process.
For that I have already write a script that gives all the PID
#!/bin/ksh
pid= `ps -ef |grep "ov" |grep -v "grep"| awk '{print $2}'`
echo $pid
if [ "$? -eq 0 ];
then
echo "process is running"
else
echo "process is not running"
fi
and o/p comes ->
19 25 40 43 44 45 46 47 48 18359 1557 2015 2016 2020 2021 2022 18236 11389 10523 12950 18239 9176 18228 29786 15867 12912 18296 24251 13650 18241 29658 16027 18307 18355 15868 18240 18305 15852 18233 18242 18243 18230 22644 15853 16003 16078 18238 18297 12728 18229 29731 16083 16097 18295 18298 19476 23290 16021
now if pid 19,18242 and 23290 is not running then hw can I log these pid in another file and start the same process??

wait(1) General Commands Manual wait(1)
NAME
wait - await process completion
SYNOPSIS
[pid]
DESCRIPTION
If no argument is specified, waits until all processes (started with of the current shell have completed, and reports on abnormal termina-
tions. If a numeric argument pid is given and is the process ID of a background process, waits until that process has completed. Other-
wise, if pid is not a background process, exits without waiting for any processes to complete.
Because the system call must be executed in the parent process, the shell itself executes without creating a new process (see wait(2)).
Command-Line Arguments
supports the following command line arguments:
The unsigned decimal integer process
ID of a command, whose termination is to wait for.
WARNINGS
Some processes in a 2-or-more-stage pipeline may not be children of the shell, and thus cannot be waited for.
SEE ALSO
csh(1), ksh(1), sh-posix(1), sh(1), wait(2).
