[GTALUG] bash seq question

[Russell Reiter]

I had to resort to analogue to get the docs out. You remember, print the
numbers on the pages, then run them through for the data.

Curse u
seq: invalid floating point argument:  1

This one liner was my magic bullet a few short kernel updates ago. Tunnel
in get the job done right and exit. Kind of like Robert De Nero in Brazil
but without the yankee screwdriver and abseiling gear.

Williams suggestions also threw seq: invalid args.

Thanks both.
