How to Show Most Recently Installed/Updated Filesets on AIX

One of the fundamental principles of troubleshooting any issue is to look for what has changed between the time things went from working to not working. One thing that could be relevant to any issue is if any software has been recently updated or installed.
AIX provides the "lslpp -h" command which will show fileset installation and update dates for each fileset. Unfortunately it doesn't sort the output of this, so it can be very difficult to look through the output to find filesets that have been recently updated or installed.
Here is a one liner that will sort the output and show you the most recently installed and updated filesets on your AIX system:
If you pipe it to "tail" you can see the 10 most recently installed or updated filesets on your AIX system:
Note: This one liner is assuming the date output will be MM/DD/YY... If you are in a different locale you might need to modify the one liner a little bit or temporarily change the environment variables to set your system to output dates in MM/DD/YY.
Also, in case you are wondering about the "sed 's/70/-70'" and "sed 's/-70/70'" parts of the script.. I noticed that lslpp -h on some servers will list the dates for some filesets as the year 70 (as in the UNIX epoch). Since "70" (1970) is bigger than "13" (2013) these old "1970" filesets were getting listed as the newest. So before the "sort" of the output I search and replace any 70's with -70's so they will be sorted correctly, and then after the sort change all the -70's back to 70. This way the dates are sorted correctly and the output still looks good.
