Now there Debian available over the Microsoft Store on Windows 10. Very small RAM usage, much better than the ubuntu version.

Open PowerShell as Administrator and run:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

Then Open the Microsoft Store and search for debian.

The File are now in C:\Users\%USERNAME%\AppData\Local\Packages\TheDebianProject.DebianGNULinux_*

I wonder why it is no longer in C:\Users\%USERNAME%\AppData\Local\lxss\

For having correct displayed german characters I had to change the console

sudo dpkg-reconfigure locales
sudo apt install console-setup
sudo dpkg-reconfigure console-setup

Open nano with

nano -wcF

ALT + G = Goto Line Number
CTRL + R = Insert File
CTRL + W = Search String or by RegEx
ALT + R = Replace string or Replace by RegEx
ALT + , = Goto previous buffer
ALT + . Goto next Buffer

A shortcut / alias for listing only hidden files and folders<

alias us="ls -la | grep ^- | awk '{print \$9}' | grep ^\\\."

There is an easy trick to display only the filename with ls -l

ls -l | awk '{print $9}'

It is very hidden how to go to a line number in linux nano editor

• strg + w
• strg + t
• enter Line number

 

Find the largest files on your linux system

cd /
du -k | sort -n | perl -ne 'if ( /^(\d+)\s+(.*$)/){$l=log($1+.1);$m=int($l/log(1024)); printf  ("%6.1f\t%s\t%25s  %s\n",($1/(2**(10*$m))),(("K","M","G","T","P")[$m]),"*"x (1.5*$l),$2);}'

 

Just installed a brand new debian and than I can’t use my working copies cause the svn version is still 1.6.x
So an upgraded is required!

 

wget http://opensource.wandisco.com/wandisco-debian.gpg -O /tmp/wd-deb.gpg
apt-key add /tmp/wd-deb.gpg
rm /tmp/wd-deb.gpg
sudo nano /etc/apt/sources.list

deb http://opensource.wandisco.com/debian wheezy svn18

So now I can have fun again! Why not git? Cause the company repos are still in svn and I had some troubles with git-svn.
