Thanks again vgersh99.. I was able to get this working. But encountered in an awk error on some files
awk: Input line 06/15/2009 05:08:18. cannot be longer than 3,000 bytes.
Alternately, I tried accomplishing this using shell script
CNT=` cat $j | grep -i $i | sed 's/'$i'/&\n/g' | grep -wi $i | wc -l `
instead of
CNT=` awk -v pat=${i} '{cnt+=gsub(pat,"&")}END {print cnt}' $j `
That seemed to work on linux, but does not on HP-UX
Any ideas what I need to change to get it working in HP-UX

GREP(1) General Commands Manual GREP(1)
NAME
grep - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines (with newlines excluded) that match the pattern, a regular expression as
defined in regexp(6). Normally, each line matching the pattern is `selected', and each selected line is copied to the standard output.
The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'.

/sys/src/cmd/grep.c
SEE ALSO

DIAGNOSTICS
Exit status is null if any lines are selected, or non-null when no lines are selected or an error occurs.
