One of those WTF moments of unexplainable distro choices. This on an ubuntu box:
$ which netcat
/bin/netcat
$ ls -l /bin/netcat
lrwxrwxrwx 1 root root 24 Oct 14 2013 /bin/netcat -> /etc/alternatives/netcat
$ ls -l /etc/alternatives/netcat
lrwxrwxrwx 1 root root 15 Oct 14 2013 /etc/alternatives/netcat -> /bin/nc.openbsd
$ which nc
/usr/bin/nc
$ ls -l /usr/bin/nc
lrwxrwxrwx 1 root root 7 Jun 4 2014 /usr/bin/nc -> /bin/nc
$ ls -l /bin/nc
lrwxrwxrwx 1 root root 20 Oct 14 2013 /bin/nc -> /etc/alternatives/nc
$ ls -l /etc/alternatives/nc
lrwxrwxrwx 1 root root 15 Oct 14 2013 /etc/alternatives/nc -> /bin/nc.openbsd
... whereas on FreeBSD:
% ls -l /usr/bin/nc
-r-xr-xr-x 1 root wheel 28008 Nov 11 2014 /usr/bin/nc
% file /usr/bin/nc
/usr/bin/nc: ELF 64-bit LSB executable, x86-64, version 1 (FreeBSD), dynamically linked (uses shared libs), for FreeBSD 10.1, stripped
Which would you rather remember?
