Conditional merge using vi
How do I do this in VI. I have a file with pattern like this..

Code:
pattern line
line1
line2
line3
line4
pattern line
line1
line2
line3
line4
pattern word
line1
line2
line3
line4

whenever the word "pattern" is found in a line, I should delete that line and 2 lines below it & merge the other two lines after that. The output should look like this at the end.

Code:
line3line4
line3line4
line3line4

vi or vim?

This should work with vim:

Code:
:%s/\(pattern\)\(.*\n\)\{3}\(.*\)\n\(.*\)/\3\4/
