Code:

index($0,srch) { $1 = $1; print }' "$FILE"

Please put code inside [code] tags.

#!/bin/bash
i=1
for a in `cat namelist`

That may work if there are no spaces in the file; it will definitely fail if there are.

To read a file line by line:

Code:

while IFS= read -r line
do
  : whatever
done < FILENAME

do
        echo "Loop$i:"
        echo "+++++++"
        grep $a testfile | tr '^' '\n'

That will fail if there's a space in the search term, and grep and tr are both unnecessary.

Code:

case $line in
   *"$a"*) set -f; printf "%s\n" ${line//^/$'\n'} "---------------" ;;
esac

        echo "----------------------------"
        i=`expr $i + 1`

There is no need to use an external command to do integer arithmetic in any POSIX shell:

Code:

i=$(( $i + 1 ))

done
