-----BEGIN PGP SIGNED MESSAGE----- [Perhaps off-topic, I'm sorry ...] Now, that's interesting. Forgive my ignorance, but what is that "substitution" really doing? It's my understanding that the start-of-line meta represents a position (immediately left of the first character in the line), and not an actual character ... which suggests that it can be located as an anchor, but not removed or altered. Obviously, the start of the line isn't "replaced" in this case ... is this just a funky way to fool the regex (e.g. unexpected, but useful, behavior)? - -d - -- David Talkington Community Networking Initiative dtalk@prairienet.org 217-244-1962 PGP key: http://www.prairienet.org/~dtalk/dt000823.asc Annelise Anderson wrote: >There are two ways I know of to comment a block of lines in vi. > >1) Turn on line numbering with :se nu ; the do: > >:7,17s/^/#/ > >This puts a # at the beginning of lines 7 through 17. > >2) Put cursor on line where you want to start the substitution >do this: > >:.,+10s/^/#/ > >That starts at the line you're on (the .) and for that line and >the next 10 lines (11 total) places a # at the beginning of the line. >This is especially useful in editing a kernel config file. > >Annelise > > >On Wed, 1 Nov 2000 8773836928@skytel.com wrote: > >> Hello, >> >> I have been editing some >> Perl scripts in vi recently, >> and I find it very annoying >> that Perl cannot comment >> blocks of code, only lines. >> >> I have been reading the docs in vi, but I can't quite figure out how >to do a substitute command that will, say, prepend a # to the >next n lines, and later remove the # ( well, the second one >I could always use :s and replace the first # with nothing >for the next n lines.
