The linux host command says capital -W specifies wait seconds, but in my case it always seems to wait longer regardless of specified seconds:
time host -W 2 2409:8a50:4be:3eb0:5cce:db14:2e63:daf6
;; connection timed out; no servers could be reached
real 0m6.008s
user 0m0.003s
sys 0m0.004s
I could forcely kill it with timeout -k 3 3 [initial command here], but I could use that timed out erorr reply; and still, why is the -W not working ?
Usage: host [-aCdilrTvVw] [-c class] [-N ndots] [-t type] [-W time]
[-R number] [-m flag] hostname [server]
-a is equivalent to -v -t ANY
-c specifies query class for non-IN data
-C compares SOA records on authoritative nameservers
-d is equivalent to -v
-i IP6.INT reverse lookups
-l lists all hosts in a domain, using AXFR
-m set memory debugging flag (trace|record|usage)
-N changes the number of dots allowed before root lookup is done
-p specifies the port on the server to query
-r disables recursive processing
-R specifies number of retries for UDP packets
-s a SERVFAIL response should stop query
-t specifies the query type
-T enables TCP/IP mode
-U enables UDP mode
-v enables verbose output
-V print version number and exit
-w specifies to wait forever for a reply
-W specifies how long to wait for a reply <<<<<<<<<<<<<<<<<<<
-4 use IPv4 query transport only
-6 use IPv6 query transport only
