Date of OS

[Griselda Sanchez]

How can I get the date of the Last installation of Operation System or update?
Thanks

swlist -v "what_ever_is_Os_product"

Look for install date.

Hi,

Try

swlist -l product -a install_date OS-Core

If the OS was installed from a ignite tape, it would show the date when OS was originally installed on the server from where the ignite tape was created.

Hope this helps.

It depends upon how you define these terms. For example, an OS update might be the last time a kernel was built -- in which case ls -l /stand/vmunix is your answer or you may mean the last time an OS patch was installed. It might also mean when did you last install a patch for a command. You MAY know this (if the logs have been left intact) by examining /var/adm/sw/sw*.log (especially swinstall.log). Also, simply executing the swlist command can tell you the last Quality pack (or equivalent) that was installed.

Try:
swlist -l bundle -a create_date |grep HPUX

Another way:

'view /var/adm/sw/swinstall.log'

Shows all software installs, with timestamps.
