cat << END
$(basename $0) Based on oratab, show nice tables of the installed and/or missing patches for some GI/DB Oracle Homes
You can then quickly find a missing patch across a RAC system
$(basename $0) will by default check all the nodes of a cluster (based on olsnodes) which requires ASM to be running
and oraenv to be working with the ASM aslias defined in oratab; If you have no ASM alias in oratab,
you may suffer from https://unknowndba.blogspot.com/2019/01/lost-entries-in-oratab-after-gi-122.html
You can specify a comma separated list of host or a file containing one host per line
$(basename $0) by default checks all the homes defined in oratab, you can use --grep/--home and --ungrep/--ignore to limit your home selection (see examples below)
$(basename $0) relies on opatch lspatches which must run as oracle user (and not root); if the script is started as root,
the opatch lspatches commands will be run after su - ${ORACLE} (see -u | --oracleuser for more on this)

cat << END
-g | --groupfile ) A group file containing a list of hosts
-c | --commalist | --hosts ) A comma separated list of hosts
-G | --grep | --oh | --home ) Pattern to grep from /etc/oratab
-v | --ungrep | --ignore ) Pattern to grep -v (ignore) from /etc/oratab
-s | --showhomes | --show ) Just show the homes from oratab resolving the grep/ungrep combinations
-u | --oracleuser ) User to use to run opatch lspatches if the script is started as root, default is ${ORACLE}
-h | --help ) Shows this help
