You can do something like this :
Code:
#!/usr/bin/ksh

#
# Define logile and searched word
#

log_file=logfile
searched_word=word
prv_line_count_file=${log_file}.prv_count

#
# Get previous line count
#

if [ -f ${prv_line_count_file} ]
then
   prv_line_count=$(<${prv_line_count_file})
else
   prv_line_count=0
fi

#
# Get actual line count and memorize it
#

line_count=$(awk 'END {print NR}' ${log_file})
echo ${line_count} > ${prv_line_count_file}

#
# If logfile is smaller, start searching at the first line
#

if [ ${prv_line_count} -gt ${line_count} ]
then
   prv_line_count=0
fi

#
# Search for word
#

awk -v num=${prv_line_count} \
    -v word="${searched_word}" \
    'NR>num && $0~word { count +=1 } END { print count+0 }' \
    ${log_file}

vlatai(1L)																vlatai(1L)

NAME

       vlatai - Lojban word analyzer

SYNOPSIS

       vlatai [ -v ] [ word ]

DESCRIPTION

       vlatai is a program that reads a list of Lojban words from standard input, one word per line.  In its usual mode, it writes a single output
       line for each input line, advising of which kind of Lojban word the input line is.   If the input word has cmavo prefixed onto  it,  vlatai
       shows the individual cmavo and the base word itself.

       In the verbose mode (obtained using -v), the workings of the internal state machines used for scanning the word are exposed.  This may give
       some insight into where an error lies on words that can't be parsed, especially if the output is used in conjuction with the  report  files
       built during the compilation process.

       Note that vlatai is primarily a testbench for the word categorizer/splitter inside jbofihe.  vlatai is not fully supported or documented as
       a stand-alone program.

OPTIONS

       -v     Verbose; show lots of information about the evolution of the internal state

       word   The word to check.  If no 'word' argument is supplied, the program reads words from standard input,  one	word  per  line  (with	no
	      whitespace around it.)
