I experienced an interesting problem: on a Debian Jessie host with squidguard: update-squidguard threw the following error-message:

root@34697f9f06a2:/# update-squidguard 
/usr/sbin/update-squidguard: 69: test: dbhome: unexpected operator
Rebuild SquidGuard database - this can take a while.

On Debian Wheezy it returns with the following error:

I got the following error while compiling a Latex-File:

compiling MyLatexfile.tex...
tex/virtualbox.tex:1: Package inputenc Error: Unicode char \u8: not set up for use with LaTeX.

So I checked the encoding of the file and saw that it looked like this:

file tex/virtualbox.tex 
tex/virtualbox.tex: LaTeX document, UTF-8 Unicode (with BOM) text, with very long lines

It seems that inputenc does not like utf-8 with Byte Order Mark. So I removed it using the following sed-command:

This is a one-liner to search for installed packages containing a searchstring and then deinstall them using "apt-get remove":

apt-get remove --purge $(dpkg --get-selections | cut -f 1 | grep DPKG-SEARCHSTRING | xargs echo " " | tr -d '\n')

So HAPPY BIRTHDAY VIM

Sometimes we have to migrate some tables from one host to another. And sometimes we want to migrate users as well. This is how I managed to do this..

First let's read out all users

mysql --batch --skip-column-names -e "SELECT user, host FROM user" mysql

Output:

I used Fluxbox/Blackbox wm for more than 10 years. It's a great window manager for people who prefer a lightweight system and  love to customize their system. Now it was time for a change...
