Top Forums Shell Programming and Scripting How to count number of results found? Post 302770871 by gary_w on Monday 18th of February 2013 05:54:54 PM

Code:
#!/bin/ksh

FILE1=x1.dat
FILE2=x2.dat

while read word
do
  # -w option to grep for searching on a word boundary.
  count=$( grep -wc "$word" $FILE2 )
  printf "%s: %d\n" "$word" $count
done < $FILE1

exit 0

Code:
$ cat x1.dat
word1
word2
word3
$ cat x2.dat
word1
word2
word3
word1
word2
word3oword1
word2
word2
word2
word3
word3
word3
word3 word3word3
$ ./x
word1: 2
word2: 5
word3: 5
$

I would advise against using tr, since that translation of the entire file is happening for each word in FILE1.
