another answer is

s = "(21:15:32:873) SMART>> Starting Process '/abs/nc/qwcy/xyz'. pid 
11560"
s =~ /^(\(.*?\)).*'\/.*?\/.*?\/.*?\/(.*?)'.*(pid \d*)/
puts $1
puts $2
puts $3

the parentheses that capture the text are call "capturing parentheses".

so the regular expression /what(.*)is(.*)this/ would sucessfully match 
the string "what mamamea this is crazy this" and the first captured 
group would be " mamamea " and the second captured group would be " 
crazy ".

Hopefully that makes sense.
