Re: [9fans] usb or lp

[Russ Cox <russcox@gmail.com>]

if the seq is causing problems that using for(c in /dev/usb?[0-9]*)
solves, then i would just use the good for loop instead and we 
can put it back.  or at least change it to 

for(c in /dev/usb^`{seq 0 16}) 

instead of

for(c in /dev/usb/^`{seq 16})

if not having usb0 is really the problem.  it's hard to tell
what you're saying the problem is.
