PID of a script file
 

Hi all,

I have a script (A.sh) to start tomcat server (catalina.sh)

After executing A.sh i need to get the PID of the A.sh file.

if i do a ps -ef | grep A.sh

doesn't return anything ,

could anybody please help me to get this done

Thanks a lot

What is in the script A.sh that keeps it running?
Remember you will only get a PID in that fashion if the script is still running or in a wait state

Post the contents of A.sh here - grail is 100% - if your script merely invokes one of the Tomcat startup scripts; your script will terminate and thus you may not see it in the ps -ef

Thanks for the quick responses alli_yas and grail

the content in my A.sh script is as follows

#!/bin/sh
if [ "$1" = "run" ]; then
exec sh $CATALINA_HOME/bin/catalina.sh run

elif [ "$1" = "stop" ]; then
exec -a pse sh $CATALINA_HOME/bin/catalina.sh stop
fi


the content in catalina.sh script is the standard catalina.sh which comes with Apache Tomcat

Thanks in advance

If you did not use the exec command ( which quits the script after the command is run ) you could then add a wait $(pidof catalina) at the end of the script to tell it to wait until catalina exits ( when you issue a STOP ) or until it dies for any reason ( if you issue a START ).

Thanks William,

that worked, when i remove the exec command

Now I'm having some other question, that is, when i do a ps - ef | grep A.sh , it outputs the PID,
then i need to execute "cat /proc/<PID>/status" and the name of the process appear as "sh"

Is there any way that i can customise the name of the process that im getting?

Thanks in advance

I'm assuming you are executing the shell script with sh, but then it will also have the process name sh.

Instead of running the script with
Make the file executable
And then execute it with either

Cool

Thanks wiliaam and all the others.

i got my prob solved

Thanks

You're welcome

Remember you can replace the grep and kill with this
Killall takes the name of the process, unlike kill which requires the PID.
