Hi,

assume the shell script

a="he is fine , thank you"

i need to search for the word "fine" in this string.

How can I do that.

grep -w "fine"

how to pass the variable $a to this grep statement.

You can do :

echo $a | grep -w "fine"

If you want to store the result in a variable :

res=`echo $a | grep -w "fine"`
