Shell Programming and Scripting

hi RTM,
Thanks for the update it works, one small help how can i liist all the parent process running on a unix machine, so that i can grep for only those.
i have all unix machine ( HPUX, AIX, SUN and IRIX)can you help me on this.

Thanks in advance.

Regards,
Pradeep Kulkarni.

To know the parent process use:

ptree [PID]

/usr/bin/ptree [ -a ] [ [ pid | user ] ... ]

ptree Print the process trees containing the specified pids
or users, with child processes indented from their
respective parent processes. An argument of all digits
is taken to be a process-id, otherwise it is assumed
to be a user login name. Default is all processes.

Pradeep,

This new problem is not in any way related to your 'process' post.

Advise you to start a new thread for a new problem (always).

hi,

the script that u had posted

#!/bin/ksh
pid=""
pid='ps -ef | grep "<process string>" | awk ' {print $2}''
echo $pid
if [ "$pid"="" ]
then
echo "process not running"
rsh <mail server> mailx -s "<etc etc process not running>" <mail.id>
else
echo service is ok
pid=""
fi


will always return a pid since grep is a process, ( u will not receive process not running message even though the actual process isnt running) need to trip off the process grep when checking for other process pids and what if the other user has the same process, u would end up with pids that are not under your control.

you can try this,
ps -ef | grep <user> | grep -v grep | grep <process string> | awk '{print $2}'

hi
while i tried for to run script
[#!/bin/ksh
pid=""
pid='ps -ef | grep "<process string>" | awk ' {print $2}''
echo $pid
if [ "$pid"="" ]
then
echo "process not running"
rsh <mail server> mailx -s "<etc etc process not running>" <mail.id>
else
echo "service is ok"
pid=""
fi
]

i got errors that are :
./pname.sh: line 1: [#!/bin/ksh: No such file or directory
./pname.sh: line 3: {print: command not found

process not running
./pname.sh: line 12: ]: command not found


i m new in linux environment and need ur favour. plz how to compile this script.

actually i need a command fron that maps process name to process id.
thx.

Hi, This is the answer to your query.

bash-3.00$ vi ProcessMonitoring.sh
#!/bin/ksh
puser=1
for name in `cat perf_listfile`
do
puser=`ps -ef | grep $name |grep root | awk ' {print $1}'`
#puser=`ps -ef | grep "jogi" |grep root | awk ' {print $1}'`
echo $puser
echo $pid
if [ $puser -eq root ]
then
echo "successful"
else
echo "This is an auto-generated mail for Process Monitoring Error. Process $name not running. From : Error Monitoring Process." | mailx -s "Process Monitoring Error : $name not running" centurygalactus@gmail.com
fi
done
