Enabling <alt>-<space> in Ubuntu for Ulauncher

If you are wanting to use <alt>-<space> as the key for the excellent Ulauncher with Ubuntu, there are a couple of tweaks that you need to do:

1. Ensure that CompizConfig Settings Manager is installed:

apt-get install compizconfig-settings-manager

2. Start the CompizConfig Settings Manager

Go to General, General options, Key bindings and disable Window Menu which is assigned <alt>-<space> by default.

Find all email that a user sent via postfix mail.log

I needed to find all the email that a user sent with only the postfix mail.log. This simple script does that. There is probably an easier way :-)

#!/bin/bash USERNAME=$1 for i in `grep -A2 $USERNAME mail.log | \
grep message-id | cut -d'<' -f2 | cut -d'>' -f1`; \
do grep "$i" /var/log/mail.log | grep "to=" | awk '{ print $7 }' | \
cut -d'<' -f2 | cut -d'>' -f1; done | sort | uniq -c

A low resource usage Pandora player - Pianobar

Pandora has become my go to choice of music player some time ago, but having a browser window open just to play music strikes me as we little crazy.

Pithos is one alternative and does a reasonable job, but I was looking for something lighter and I found it with Pianobar.

Theres a bunch of features, it works a treat, and is very lightweight compared to Pithos.

Give it a try, maybe you'll prefer a non-gui too.

Ubuntu winbind not working?

Have you been trying to get winbind working on Ubuntu, and not having any luck? After the usual:

 

sudo apt-get install winbind

 

You also need to install libnss-winbind as well:

 

sudo apt-get install libnss-winbind

 

That should get it working, when combined with the change of the hosts: line in /etc/nsswitch.conf from:

 

hosts: files dns

 

to

 

hosts: files dns wins

 

And presto, it should start working.
