Generating Mock Userdata

I often find myself needing to generate dummy data when doing software projects. The rig command-line utility makes it easy to do so.

# apt-get install rig

$ rig

Removing Lines that Don't Match a Pattern

Following up on a previous tip, you can also use the "g" and "d" commands to remove lines in your current buffer that don't match a specific pattern. The following example would remove all lines that don't match "www.example.com".

:g!/www\.example\.com/d

Finding and Replacing Unicode Characters

If you'd like to find a particular multibyte character, you can do the following.

/\%u001c

You can also do a find and replace as you normally would.

%s/\%u001c//g
