[ILUG] grep'ing for multiple lines

[Richard Eibrand]

Howdy,

I've been doing my nut in for a while now, trying to extract two lines of 
text from a file. I've unsuccessfully tried many grep and sed options, to 
no avail. Eventually I used grep -C 2 <Regexp> <file> to get the lines I 
wanted. That was primarily because the lines I wanted happened to closely 
located. Below (1) is an example of the file I'm grep'ing. I'm only 
looking for the lines with "Distance:..."and "1., Trap...".

How can I use grep to extract only those lines without using the -C 
option? To get for example "Distance:..." and "2.,Trap ..."?

TIA for any suggestions, R
