Comparing a text file's entries with ps -ef output
Shell : Korn
os : AIX

This is the ps output looking for a process called pmon. pmon runs with various 'service' names which is appended with an underscore as shown below.

For example a pmon process for the service hexjkm will be named ora_pmon_hexjkm


HTML Code:
$ ps -ef | grep pmon

Every morning I need to check a set of mandatory processes (listed in mustRun.lst) and make sure that it is running (ie. present in ps output)

So, I need to find the service names which are present in mustRun.lst file but absent from ps -ef output. Is there any way to do this using scripting ?

try something like below
Code:
ps -ef | grep pmon > psOracle.dat
awk  'FILENAME=="psOracle.dat"{A[$1]=$1} FILENAME=="mustRun.lst"{if(A[$1]!=$1){print}}' psOracle.dat mustRun.lst
