PORCHGEN(1) General Commands Manual PORCHGEN(1) NAME porchgen -- porch script generator SYNOPSIS porchgen -f scriptfile command [argument ..] DESCRIPTION The porchgen utility generates an orch(5) sxript based on user interaction with the spawned command. The following options are available for porchgen: -f scriptfile Names the scriptfile to create. -h Show a usage statement. porchgen operates by first spawning the requested command, then polling for both output from the command and input from the user. A spawn() statement is written to the scriptfile to match the command passed in. Output from the command is sent immediately to the user as it comes in, and internally recorded. When a line comes in from the user, porchgen records a match() block from the last line of output recorded, and adds up to two previous lines of output in commented out match() blocks for context that might have been necessary. A write() statement is then issued for the line received before it is passed along to the command. Execution continues and blocks are emitted until either stdout of the com- mand or stdin of porchgen reach EOF. EXIT STATUS The porchgen utility exits 0 on success, and >0 if an error occurs. EOF on the command stdout is considered an error if the process was signalled or exited with a non-zero exit code. EOF on stdin is currently always consid- ered an error.
