The zsh/net/socket module makes available one builtin command:
zsocket is implemented as a builtin to allow full use of shell command line editing, file I/O, and job control mechanisms.
Open a new Unix domain connection to filename. The shell parameter REPLY will be set to the file descriptor associated with that connection. Currently, only stream connections are supported.
If -d is specified, its argument will be taken as the target file descriptor for the connection.
In order to elicit more verbose output, use -v.
File descriptors can be closed with normal shell syntax when no longer needed, for example:
exec {REPLY}>&-
zsocket -l will open a socket listening on filename. The shell parameter REPLY will be set to the file descriptor associated with that listener.
If -d is specified, its argument will be taken as the target file descriptor for the connection.
In order to elicit more verbose output, use -v.
zsocket -a will accept an incoming connection to the socket associated with listenfd. The shell parameter REPLY will be set to the file descriptor associated with the inbound connection.
If -d is specified, its argument will be taken as the target file descriptor for the connection.
If -t is specified, zsocket will return if no incoming connection is pending. Otherwise it will wait for one.
In order to elicit more verbose output, use -v.
