Short answer        s string-to-be-searched  gn   For learning   There are 3 modes in VI editor as below      you are entering from Command to Command-line mode  Now  whatever you write after   is on CLI Command Line Interface   s specifies all lines  Specifying the range as   means do substitution in the entire file  Syntax for  all occurrences substitution is   s old-text new-text g g specifies all occurrences in the line  With the g flag   you can make the whole line to be substituted  If this g flag is not used then only first occurrence in the line only will be substituted  n specifies to output number of occurrences    double slash represents omission of replacement text  Because we just want to find    Once got the number of occurrences  you can Press N Key to see occurrences one-by-one   For finding and counting in particular range of line number 1 to 10        1 10s hello  gn    Please note    for whole file is repleaced by   separated line numbers      For finding and replacing in particular range of line number 1 to 10        1 10s helo hello gn

similar as Gustavo said  but additionally       For any previously search  you can do simply      s   gn   A pattern is not needed  because it is already in the search-register              - do s  in the whole file  g  - search global  with multiple hits in one line   n  - prevents any replacement of s  -- nothing is deleted  nothing must be undone   see   help s flag for more informations    This way  it works perfectly with  Search for visually selected text   as described in vim-wikia tip171

use       s pattern  0 g   when pattern string is too long and you don t like to type it all again

I suggest doing    Search either with   to do a  bounded search  for what s under the cursor  or do a standard  pattern search  Use   s   gn to get the number of occurrences  Or you can use   s   n to get the number of lines with occurrences       I really with I could find a plug-in that would giving messaging of  match N of N1 on N2 lines  with every search  but alas   Note  Don t be confused by the tricky wording of the output  The former command might give you something like 4 matches on 3 lines where the latter might give you 3 matches on 3 lines  While technically accurate  the latter is misleading and should say  3 lines match   So  as you can see  there really is never any need to use the latter   n  only  form  You get the same info  more clearly  and more by using the  gn  form

You need the n flag  To count words use     s  i    amp  gn      and a particular word     s the  amp  gn           See count-items documentation section   If you simply type in    s pattern pattern g   then the status line will give you the number of matches in vi as well
