I have a table in a file (piped).  I wanted to count the occurrence of a particular word XXX.  How do I do that in shell?

Would this miss the case where there are more than one matches?

#!/bin/ksh
typeset -i mCnt=0
mWord='aaa'
for mEach in `cat input_file`
do
  if [ "${mEach}" = "${mWord}" ]; then
    mCnt=${mCnt}+1
  fi
done
echo 'Total words for '${mWord}' = '${mCnt}

grep -c would count lines with that word, no matter how many words found on that line.



# egrep -o pattern file|wc -l

if you want exact match add -w option and if you want to ignore case add -i option
