To count the number of matches of a pattern, you could enter a substitute command such as
:%s/pattern/foo/g
After viewing the count in the status line, press u to undo the change.
However, in recent versions of Vim, there is a better procedure. The following will display the count, but will not change the buffer.
:%s/pattern//gn
Similarly you can display the number of lines the pattern matches by omitting the g.
:%s/pattern//n
In newer versions of VIM, if you want to know the amount of matches of some lines, you may use the substitute command without the % such as:
:3s/pattern//gn
or
'<'>s/pattern//gn
