Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Adapted using your usefull comments !

Know a better way?

If you can do better, submit your command here.

What others think

it's safer to grep for today's date. SO, grep and awk part should be replaced with the following

grep -e `date +%Y-%m-%d` /var/log/dpkg.log | grep install | awk '{print $5}' | uniq

then add xargs

Without mentioning the date, all packages installed since login will be removed, if i'm not wrong.

The --purge isn't necessary. If that was left out, you could at least experiment with the command without losing config files from packages that are to be deinstalled.

On my ubuntu system, dpkg seems to rotate the /var/log/dpkg.log file every month, so the above command would *purge* anything you installed this calendar month.

Another useless use of grep. How about taking advantage of awk?

awk '/install / {print $4}' /var/log/dpkg.log
