Without using any external utility, you can do this in bash:

echo "${PWD##*/}"

4

Or using awk:

awk -F/ '{print $NF}' <<< "$PWD"

You could set the field separator to / and print the last field if the second last field is insta

pwd | awk -F / '{
  if ($(NF-1) == "insta") {
    print $NF
  }
}'

Output

4

Or you could print the last field:

pwd | awk -F / '{print $NF}'
