It should be doable with a simple find.

find "XYZ" myfile.txt > myfile2.txt

this will produce myfile2.txt which contains only those lines containing
the 
text XYZ

You may get extra lines, however, if XYZ is contained somewhere else in a 
line and not the front.  If it is unique enough you won't get as many
false 
hits.
