how do i get a word that exists between two words

eg: this is bryan
My input to command would be this and bryan
and output should be 'is'

Is there a command i can use?

Try...

Code:

eg="eg: this is bryan"
w1="this"
w2="bryan"
result=$(echo $eg | awk -v w1="$w1" -v w2="$w2" 'match($0, w1 ".*" w2){
   print substr($0,RSTART+length(w1),RLENGTH-length(w1 w2))}')
echo $result
