When i execute the following command ps -ef |grep tomcat it shows me the following process

abcapp   28119     1  0 12:53 ?        00:00:19 /usr/java/jdk1.6.0_10//bin/java -Xmx256m -Dabc.log.file=/home/app/apps/rum/logs/dev.log -Dabc.config=dev -Dlog4j.configuration=file:///home/abcapp/env/abc_env/abc_env-1.2/config/log4j-webapp.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file=/home/abcapp/env/tomcat/tomcat-5.5-26-rum/conf/logging.properties -Djava.endorsed.dirs=/home/abcapp/env/tomcat/tomcat-5.5-26-rum/common/endorsed -classpath :/home/abcapp/env/tomcat/tomcat-5.5-26-rum/bin/bootstrap.jar:/home/abcapp/env/tomcat/tomcat-5.5-26-rum/bin/commons-logging-api.jar -Dcatalina.base=/home/abcapp/env/tomcat/tomcat-5.5-26-rum -Dcatalina.home=/home/abcapp/env/tomcat/tomcat-5.5-26-rum -Djava.io.tmpdir=/home/abcapp/env/tomcat/tomcat-5.5-26-rum/temp org.apache.catalina.startup.Bootstrap start

pgrep only search for the process name without the full path (in your case only java) and without arguments.

Since tomcat-5.5-26-rum is part of the latter, i'd search the pid with

ps -ef | grep tomcat-5.5-26-rum | grep java | awk ' { print $2 } '

The double grep is useful to discard the grep pids itself

    If someone, like me, is looking for one line code to kill tomcat. (Assuming you have only one tomcat installed & running). It works on my Centos 7. `sudo /bin/kill -15 $(ps -ef | grep tomcat | grep java | awk ' { print $2 } ')` – Yang Apr 04 '19 at 06:41

Just add following line at the start of catalina.sh file

CATALINA_PID="$CATALINA_BASE"/logs/tomcat.pid

OR 

CATALINA_PID=/tmp/tomcat.pid

And bounce tomcat. This will create a tomcat.pid file in the given path and put the Tomcat process pid in it.

This worked for me:

This will give the process id of current running tomcat

echo ps aux | grep org.apache.catalina.startup.Bootstrap | grep -v grep | awk '{ print $2 }'
