I suspect this has been answered before, but I don't know what this is called, so I can't really search for it.
How come this works :
$ grep H=p <(udevadm info /dev/ttyUSB0) E: ID_PATH=pci-0000:00:1d.0-usb-0:1.5.2:1.0
But this doesn't ? :
$ sudo grep H=p <(udevadm info /dev/ttyUSB0) grep: /dev/fd/63: No such file or directory
Nevermind the fact that sudo isn't necessary in this case, please.
