bash - Reverse order of a string -

i want "reverse" order of 4 octets (bytes) make ip address.

suppose have ip:

202.168.56.32

i need convert into:

32.56.168.202

and remove first octet in reversed ip. final result:

56.168.202

my attempts:

echo 202.168.56.32 | rev

but it's returning :

23.65.861.202

this should trick:

echo 202.168.56.32|awk -f. '{print $3"."$2"."$1}'

you bash arrays:

ip=202.168.56.32 parts=(${ip//./ }) echo ${parts[2]}.${parts[1]}.${parts[0]}
