Shell scripting-subdirectories calculation

Question

Write a shell script takes the name a path (eg: /afs/andrew/course/15/123/handin), and counts all the sub directories (recursively).

Ex. /afs/andrew/course/15/123/handin should give me 6. I tried with the Find command,but the path which i am giving is being accepted.

Answer 1

simple AWK can do that

root@freebsd:~ # echo /afs/andrew/course/15/123/handin | awk -F / '{ print NF-1}'
6
root@freebsd:~ #
