How to remove spaces on a line?
Hi, suppose I have the following data:

Code:
 
albert music=top40 age=20
bob music=punk rock age=25
candy music=r n b age=22
dave music=mozart or bach only age=30

I want to extract and manipulate the music column but it's got spaces in it. How can I substitute the space with an underscore like this:

Code:
 
albert music=top40 age=20
bob music=punk_rock age=25
candy music=r_n_b age=22
dave music=mozart_or_bach_only age=30
