I'm trying to compare sun patch levels on a server to those of what sun
is recommending. For those that aren't familiar with sun patch
numbering here is a quick run down.
A patch number shows up like this:
113680-03
^^ ^^
patch# revision
What I want to do is make a list. I want to show what server x has
versus what sun recommends, and if the patch exists, but the revision
is different, I want to show that difference.
Here are some sample patches that sun recommends:
117000-05
116272-03
116276-01
116278-01
116378-02
116455-01
116602-01
116606-01
Here are some sample patches that server x has:
117000-01
116272-02
116272-01
116602-02
So there are some that are the same, some that sun recommends that
server x doesn't have, and some where the patch is the same but the
revision is different.
I've thrown the data into dictionaries, but I just can't seem to figure
out how I should actually compare the data and present it. Here's what
I have so far (the split is in place because there is actually a lot
more data in the file, so I split it out so I just get the patch number
and revision). So I end up with (for example) 116272-01, then split so
field[0] is 116272 and field[1] is 01.
def sun():
sun = open('sun-patchlist', 'r')
for s in sun:
sun_fields = s.split(None, 7)
for sun_field in sun_fields:
sun_field = sun_field.strip()
sun_patch = {}
sun_patch['number'] = sun_fields[0]
sun_patch['rev'] = sun_fields[1]
print sun_patch['number'], sun_patch['rev']
sun.close()
def serverx():
serverx = open('serverx-patchlist', 'r')
for p in serverx:
serverx_fields = p.split(None, 7)
for serverx_field in serverx_fields:
serverx_field = serverx_field.strip()
serverx_patch = {}
serverx_patch['number'] = serverx_fields[0]
serverx_patch['rev'] = serverx_fields[1]
print serverx_patch['number'], serverx_patch['rev']
serverx.close()
if __name__=='__main__':
sun()
serverx()
Right now I'm just printing the data, just to be sure that each
dictionary contains the correct data, which it does. But now I need
the comparison and I just can't seem to figure it out. I could
probably write this in perl or a shell script, but I'm trying really
hard to force myself to learn Python so I want this to be a python
script, created with only built-in modules.
Any help would be greatly appreciated,
Rick
