The gusto utility implements a datagram UNIX domain socket client. It allows
for request-response communication with an another process that exposes a
server UNIX domain socket.
The gusto utility can be built using the standard Makefile system as
follows:
$ make
$ ls -lah bin/gusto
In order to display the help message, use the -h option:
$ bin/gusto -h
In order to initiate request-response communication with a server that exposes a UNIX domain socket, use the positional argument:
$ bin/gusto /path/to/socket
The two main alternatives are socat with the UNIX-CLIENT mode, and the
OpenBSD-extended nc with options -u and -U. The reasons for writing
gusto were threefold: education, minimalistic implementation and full control
over all aspects of the communication (i.e. all flags passes to system calls,
memory allocation).
The gusto utility is written in the C99 language without any extensions. It
uses the POSIX.1-2008 interface to communicate with the kernel. Any environment
that supports there two standards should be able to compile and run the
utility. If this is not the case, feel free to contact the author.
