Why not
:g/[abc]1/m$
if you're guaranteed those patterns are unique to the lines you want to
get?
If you want discrete labels only, eg, "a1", "b3", "c5", etc., ie, those
that don't fit a particular regexp pattern, then
:g/a1\|b3\|c5\|.../m$ ("..." meaning "etc.", not taken
literally)
will do it.
Quick example, if I have a bunch of webpages where I want to get rid of
the prepended paths to each image, .js file, etc., and they fit the
pattern
wu1_files/imageX.jpg in file 'wu1.html'
wu3_files/imageY.jpg in file 'wu2.html'
etc., I'll edit the whole clump of files in one shot, then do
:argdo g/wu[0-9]_files\//s///g
to get rid of them and leave just
imageX.jpg
imageY.jpg
respectively. Where those files wouldn't fit the 'wu\d' pattern, I
would have to do something like a generic
:argdo g/[a-zA-Z0-9]*_files\//s///g
or more specific
:argdo g/name1_files\/\|name2_files\//s///g
instead.
