Probably the right thing to do is: in one shell: $ cat < fifo in the other shell: $ exec 6>fff $ echo hello >&6 $ echo more >&6 .... $ exec 6>&- (or something similar). Or a more similar approach to your one also seems to work: $ cat <> fifo One thing that is different on cygwin to linux, is if there are multiple readers of a fifo. shell 1: $ cat fifo shell 2: $ cat fifo On linux, both keep waiting for someone to write to the fifo. On cygwin, when the second cat tries to listen on the fifo, they both exit. I don't know how fifos are supposed to work, but I'm guessing cygwin gets it wrong here.
