will give you a list of packages in cronological order. That you can
then edit and feed to apt-get. Like I said, I don't know why you want
to do it, but I found it fun creating that line.
I'm just getting started with awk, but this seems to work:
ls -lt /var/lib/dpkg/info/*.list | sed 's/.*\(200[0-9]\)/\1/g' |
awk '$0 > "2007-03-01"' | awk -F"/" '{print $6}' |
awk -F"." '{print $1}' > list.txt
This produces a list of packages altered after 2007-03-01. You can
change that date around, or extend it to select a particular hour or
minute on that day to use as the cut-off.
Note that I have no idea what you're doing, or how dpkg works, I just
wanted to see if I could figure out a solution to the immediate
problem with sed and awk!
Now that's what I call a command! Good job Tyler. I hope Bob likes it.
Fantastic, thanks very much, you've inspired me, now I'm going to read
the man pages and workout how those commands work, I've always found sed
& awk a bit intimidating but they're obviously very powerful for list
processing which I seem to do a lot, I find that starting with a working
command or script and pulling it apart is the best way to learn.
As for why I'm doing this, well I have a PC which is ultimately
earmarked to be a headless MythTV BackEnd but I've been using it to
experiment with packages to figure out which ones I like for my personal
desktop and also for a couple of old P!!!s I have as MythTV FrontEnds
and would like to guests girlfriends and me to be able to surf the web
and edit a document at, consequently it has lodes of stuff installed on
it that I don't want, I was just about to reinstall Etch to clear it
when I thought this way would be an interesting learning experience and
a challenge for me, this list and apt.
Ultimately if it doesn't work I'm running apt-proxy on my file server so
a reinstall doesn't take long.
Thanks for all your help I'll post my results
