OK I have scripts (i renamed them and done some maintenance)
a) startTOMCAT.sh
b) startApp.sh
c) killapp.sh

startTOMCAT.sh
Code:
#!/bin/csh
echo $CATALINA_HOME
$CATALINA_HOME/bin/catalina.sh start

startApp.sh
Code:
#!/bin/sh
rm /opt/tmp/restart.txt     

./startTOMCAT.sh            

while :; do
     if [[ -e /opt/tmp/restart.txt ]]; then
          ./killapp.sh            
          sleep 30               
          break
     fi
done

./startTOMCAT.sh

exit 0

and killapp.sh
Code:
#!/bin/sh
var1=`ps -ef | grep -v grep | grep java | grep username| awk '{print $2}'`
kill -9 $var1

Looks flawless to me. I checked it and it works.
Do you still get that
Quote:
./startApp.sh: [[: not found
all the time?

Try single [ ] instead of double [[ ]] and see if something changes. What shell is your system's default? bash? ksh? ...?

That is what i do not understand. It shouldd work
my default is bash (i like it)
I removed "[[" and left "[". It is better now.
that is the output
Code:
/opt/tmp/restart.txt: No such file or directory
Using CATALINA_BASE:   /opt/apps/tomcat
Using CATALINA_HOME:   /opt/apps/tomcat
Using CATALINA_TMPDIR: /opt/apps/tomcat/temp
Using JRE_HOME:       /opt/java/1.6/
./startApp.sh: test: argument expected

That is what i get. I have just copied restart.txt to /opt/tmp/ and app is still working - no restart.

Hm, change the #!/bin/sh to #!/usr/bin/bash and make sure your bash is located there.
Try again.

You are THE MAN. I always used #!/bin/sh or #!/bin/csh and had never problems before
That fixed it. Additionally I had to change that sctipt (small loop) because it did the stop/start/restart 1only. If i want to doit more than 1 it will not work. I have to call startApp.sh from startApp.sh (i know i should not)
startApp.sh
Code:
#!/bin/bash
rm /opt/tmp/restart.txt
./startTOMCAT.sh

while :; do
     if [ -e /opt/tmp/restart.txt ]; then
          ./killapp.sh
          rm /opt/tmp/restart.txt   
          sleep 30
          break
     fi
done
./startApp.sh
exit 0

Thank you
