[SOLVED] Shell utility for making a UNIX domain socket?

Turbocapitalist · 06-07-2017, 04:39 AM

Is there a utility available that can make a UNIX domain socket right from the shell? Or do I have to use perl, python, or something else to make one?

For example:

Code:

srw-rw----  1 root  wheel       0B Jun  4 15:10 test.sock

The utility mknod can make a few special files, including named pipes, but not sockets. The utility touch can only make regular files. Maybe there is something just for sockets?

netcat is what you want (often under the nc command).

from man nc:

Quote:

-U' Specifies to use Unix Domain Sockets.

nc -U $PATH

Thanks. That does it, though the -l option seems to be needed.

Code:

nc -l -U /tmp/foo.sock & kill $!;

Right, I forgot you wanted a "listening" socket...
Also recommended with -l is

Quote:

-k Forces nc to stay listening for another connection after its current connection is completed. It is an error to use this option without the -l option.
