How to find whether patches are present????

[Paul Wewel]

I have software that requires that some patches are present. How do I list installed patches and O/S levels like 11.11?
Better yet, how do I grep the list to see if I have a certain patch. Any help would be appreciated.

do the command> swlist -l fileset | grep PHXX
or grep

It's always good to know the state:
# swlist -l fileset -a state |grep -i ph

[Rick Garland]

The swlist -l product command will accomplish this. If you want to know about a specific patch, swlist -l product | grep

And check the state of patches. swlist -l fileset -a state

Check in /var/adm/sw/patch.

Do ls -ld PH*|pg

Also use:
uname -a
