how to match all files that start with the string OS_PATCH and ended with .gz
remark - the solution must to fit Linux and Solaris OS
this task could be by find command or maybe with ls with Regular Expressions or any other idea for example awk
for example
OS_PATCH-ver.4.577.gz
OS_PATCH-pilot-install.gz
OS_PATCH.upgrade-patch.gz
OS_PATCH_generig-patch.gz
