The NF variable in Awk represents the Number of fields that you have
got in your current record line. So when you say `print $(NF - 1),
$NF` you are printing the (No. Of Fields - 1)th and the (No. Of
Fields)th record. So in order to just print the last but one field,
you'll just have to print $(NF - 1) and remove the $NF. So your
command becomes
subject=$(echo $PWD | awk '{print $(NF - 1)}' FS='/' OFS='/')
If you are spending quite a bit of time doing things like this, I
would recommend spending a while to learn tools like sed and awk. They
will be extremely useful.
Here[1] is one resource to get you started.
