How to use the awk to print the output

Question

This command nstats gives me output like below. How can I use awk or grep to give me the uptime with only days on it? I cannot use the "" to get the output.

HOSTNAME  LOAD  MEMORY  SWAP  PROCS  TIME  UPTIME
Server    0.01     9%     3%    54  10:39  22 days 10:16:03

Answer 1

With grep - egrep -o "[0-9]+ days"

(your nstats command) | sed -n '2p' | egrep -o "[0-9]+ days"
22 days

With awk - awk '{print $14,$15}'

(your nstats command) | sed -n '2p' | awk '{print $7,$8}'
22 days

With awk (just the days) - awk '{print $14}'

(your nstats command) | sed -n '2p' | awk '{print $7}'
22
