Named Pipes
I wanted to use a named pipe to provide random images. I know I can use
a program in a loop writing to the pipe, but that means starting the
program initially (from say a init.d or xdm startup script) where it
sits blocked until read from.
Question:
Is there a way in Linux to have the action of the reading program
opening the pipe (for reading) start up the writing program?
For example, if output_image.pl is a script that writes an image to a
named pipe, is there a way to associate it to a pipe where you can say:
$ display some_named_pipe
and have that action execute the program output_image.pl?
I'm just wondering if there's a way to avoid starting the writing
program.
