Hi All: I am not very familiar with Unix OS, Let us say, after i logged in to my unix account, what is the command i should use to find out whether or not TomCat is installed??
Well, you might find out if it's running with something like
ps -ef | grep catalina
If you get back a line that says anything other than "grep catalina", then it's probably running.
If it's not running, then you might start searching around. Try
ls /usr/local
to see if there's an "apache-tomcat-XXX" directory in the standard install location. If you don't care about making the admin mad, a last resort might be
find / -name catalina.sh -print
which will give you the path to catalina.sh (in Tomcat's bin directory) if Tomcat is installed anywhere you're allowed to look. This command might run for a long time.
