NF is the mean "The Number of Fields" in the current input record.
check this..

Code:

# echo $pathx|awk -F"/" '{print NF}'
10
total fields count is 10

So while your FS --> '/'
your $2--> home
your $5--> bad_BAD
$NF = $10 --> work (last element)

Code:

# set pathx="/home/abs/cad/bad_BAD/vdhingra/testcases/ABC/924/work"
set b=`echo $pathx | awk -F\/ '{print $(NF-2)}'`  # 8.the element
set c=`echo $pathx | awk -F\/ '{print $(NF-1)}'`   # 9.the element
# echo $b $c
ABC 924
