  Find directory in linux:

find / -name 'httpdocs' -type d
Find Files
find -name met*
The above command would start searching for the files that begin with the letters 'met' within the current directory and the directories that are present within the current directory. Since the directory is not specified as the the second parameter, Linux defaults to using the current directory as the one to start the search in.

Run second command after first command executes successfully

to_be_checked_and_alerted_script.sh && echo OK

or to restart tomcat

shutdown.sh && startup.sh
