print the last character of a string using awk

[lawrenzo_1]

Hi all,


how can I use awk to print the last character of a given string?

I need this to determine what status a server is being reported ie:

server1
server2
server3

if String = 1 standby
if String = 2 active
if String = 3 unknown

so it is important that the last char is printed.

many thanks

Chris.

If server1 server2 etc are the actual names:

awk -F"server" '{ print $2 }'

you could also remove "server" with sed:

sed 's/server//'

Hi Chris:

# X="a b c d e f"
# echo $X|awk '{print substr($0,length($0),1)}'
f
