This program serves as an interface for network sockets for use in both
shell scripts and manually from the command line. In contrast to
netcat, it handles EOF in a way so, for example, tar archives can
easily be transferred. See the man page (man 1 sock) for more details.

Example:

host1 # sock -l :7777 > file
host2 # cat file | sock host1:7777

host1 # sock -l :7777 | tar xvzfp -
host2 # tar czfp - some/dir | sock host1:7777
