Search and delete lines in vim

vim is great editor but one must remember some commands. Sometimes we want to delete line as per the search criteria. vim is capable of that also. To delete the lines as per search use

:g/editor choice/d

This will delete all the lines that have the word "editor choice". Offcourse we can use regular expression too.

:g/regex/d

Pretty simple g tells to do thing globally. / for pattern enclosing . d for deleting.

Enjoy vim :)

Installing / adding fonts in ubuntu

Ubuntu comes with variety of fonts. But if we still have an urge for installing some extra fonts from windows or some other fonts how we do it. To add the fonts in ubuntu is very easy and can be done in few steps.

Fonts normally get installed in /usr/share/fonts/truetype. Simple way of adding font is to make one folder in said path and copy the font files in it. To open this folder with root access type sudo nautalius. This will open the file explorer in root mode.

The other way is to add the fonts in /home//.fonts

To refresh or update font cache run sudo fc-cache -f -v.
