How to count the number of occurences of this pattern?
Hi all,
I have a pattern like this in a file:
123 4 56 789
234 5 67 789
121 3 56 789
222 4 65 789
321 6 90 100
478 8 40 789
243 7 80 789
How can I count the number of occurences of '789' (4th column) in this set...?
Thanks for all your help!

tbl(1) User Commands tbl(1)
NAME
tbl - format tables for nroff or troff
SYNOPSIS
tbl [-me] [-mm] [-ms] [filename]...
DESCRIPTION
tbl is a preprocessor for formatting tables for nroff(1) or troff(1). The input filenames are copied to the standard output, except that
lines between .TS and .TE command lines are assumed to describe tables and are reformatted.
If no arguments are given, tbl reads the standard input, so tbl may be used as a filter. When tbl is used with eqn(1) or neqn, the tbl
command should be first, to minimize the volume of data passed through pipes.
OPTIONS
-me Copy the -me macro package to the front of the output file.
-mm Copy the -mm macro package to the front of the output file.
-ms Copy the -ms macro package to the front of the output file.
EXAMPLES
Example 1: Using tbl
As an example, letting `@' (at-sign) represent a TAB, which should be typed as an actual TAB character in the input file
