how do you get the patching history

hi,
folks i have a challenging problem for you. i need to get the patching history, like what date the patch was applied and from which patch has it been upgarded to the current level.

i have tried everything and and all resources available but did not find a suitable answer. can some1 help, it will be really great

The command you're looking for is "lslpp -h".

pSeries and AIX Information Center - lslpp command

gus2000 is correct. If you are looking for the revision history of a specific program instead (it was not clear to me what you meant) use the command "what".

For example:

# what /usr/bin/ls
/usr/bin/ls:
        61      1.15  src/bos/usr/ccs/lib/libc/__threads_init.c, libcthrd, bos53H, h2006_10B1 3/5/06 16:44:58
        45  1.21.8.2  src/bos/usr/bin/ls/ls.c, cmdfiles, bos53H, h2006_24B4 6/14/06 23:25:27
