Public bug reported:

Hey,

netcat shows a usage error if i try to use the "-t" option:

Example in Bionic:

$ netcat -s 127.0.0.1 127.0.0.1 22 < /dev/null 
usage: nc [-46CDdFhklNnrStUuvZz] [-I length] [-i interval] [-M ttl]
          [-m minttl] [-O length] [-P proxy_username] [-p source_port]
          [-q seconds] [-s source] [-T keyword] [-V rtable] [-W recvlimit] [-w 
timeout]
          [-X proxy_protocol] [-x proxy_address[:port]]           [destination] 
[port]


Example in Xenial:

netcat -s 127.0.0.1 127.0.0.1 22 < /dev/null 
SSH-2.0-OpenSSH_7.2p2 Ubuntu-4ubuntu2.4


Manpage shows that the option is still availible and should work. Both systems 
use openbsd netcat.

$ type netcat
netcat is hashed (/bin/netcat)
$ ls -lah /bin/netcat 
lrwxrwxrwx 1 root root 24 Apr 25 21:56 /bin/netcat -> /etc/alternatives/netcat
$ ls -lah /etc/alternatives/netcat
lrwxrwxrwx 1 root root 15 Apr 25 21:56 /etc/alternatives/netcat -> 
/bin/nc.openbsd
