Re: [vox-tech] serendipity with vim



Here:

   :%s/pattern//g

   % means "for each line"
   s means "replace"
   g means "for all occurrences in that line"

So without %, it'll replace all occurrences of "pattern" on the line
you're on.  With % but without g, it'll replace the first occurrence of
"pattern" for each line for the entire file.  Without % and without g,
it'll replace the first occurrence of "pattern" only on the line you're
on.

Also... instead of %, you can specify the line range inside brackets using
line numbers (kind of a hassle), or you can select the range you want via
Ctrl-v before typing ":s/pattern//g" and Vim will figure out the line
range by itself (really slick).
