I used the nslookup command but... is there an easier way of doing it... just like hostname command.
When i give this command i get the following
Code:
nslookup 10.2.47.36
Server:      10.233.04.31
Address:    10.233.04.31$35

13.29.28.10.in-addr.prap            name = cinderella.apm42.local.

Now I'm only interested in the word cinderella over here so i used the following


Code:
nslookup 10.2.47.36 | grep name

I just want to get the word cinderella and assign it to a variable how do i do it

only an awk away Smilie
Code:
nslookup 10.2.47.36 | grep name | awk -F= '{print $NF}'
