Delete lines containing and remove the blank line at the same time

Is there a way to delete a line containing something and the blank line at the same time?

If you do this it leaves a blank line behind.

Code:
sed '/yum/d' .bash_history

I know this works but I would think there would be a way to do it with one command

Code:
 sed '/yum/d' .bash_history | sed '/^$/d'

In vi this also leaves a blank line behind.

Code:
:g/yum/d

In vi this removes the blank line.

Code:
:g/^\s*$/d

# 2  
try..
Code:
sed -e '/yum/d' -e '/^$/d' .bash_history

# 3  
or try
Code:
sed '/^$\|yum/d'

Code:
sed -n '/^$\|yum/!p'
