X3270if

x3270if is a utility program for interfacing with the x3270 family. It implements the client side of the s3270 protocol, making it easy for simple scripts to communicate with the emulator. It also implements the x3270&gt; prompt on all of the emulators except c3270 and wc3270.

If the method to connect to the emulator is not specified on the command line, x3270if will use the environment variables set by the Script action to make the connection via pipes or a TCP socket. It will not use HTTP.

Command-line parameters

 * -i
 * Shuttle raw data between stdin/stdout and the emulator.


 * -H action
 * Display action as the name of the action to invoke for help information. Requires -I.


 * -I prompt
 * Implement the x3270&gt; prompt with prompt as the prompt string.


 * -p pid
 * Connect to the emulator via the Unix-domain socket associated with process ID pid. (POSIX only.)


 * -P
 * Use pipe file descriptors instead of a socket, if both are available from the environment. (POSIX only.)


 * -s index
 * Display the prompt field index (0..12).


 * -S
 * Display the entire prompt string.


 * -t port
 * Connect to the emulator via 127.0.0.1, port port, using the s3270 protocol.


 * -v
 * Enables verbose operation, tracing input and output data to standard error output.


 * --version
 * Display version information and exit.

Unless -i, -I, -s, -S or --version is given, a single positional option must be supplied, which specifies an action and optional parameters. The output of the action will be written to standard output. Exit status from x3270if will be 0 if the action succeeds, 1 if it does not.

The -i, -I and -s/-S parameters are mutually-exclusive.

Examples
Run a simple command from a script. x3270if "String(hello)" Run a command from an external script, connecting to a port specified by the emulator option. x3270if -t 9999 "String(hello)" Implement the x3270&gt;, with  as the prompt. x3270if -I xyz3270
