1) find text in the matching files and show the filename with the pattern. The below example shows the list of filenames and the location of the hostname in those files, which will be helpful when changing hostnames for your websphere installation.
find . -name ‘*.xml’ -print | xargs grep ‘hostName’ /dev/null
bash-2.05b# find /usr/IBM/WebSphere/AppServer/profiles/AppSrv01/config/ -name ‘server*.xml’ -print | xargs grep ‘hostName’ /dev/null | more
