Closing this now since existing tools can do it quite efficiently.
Some more examples:
text lines clocking patterns: (pass to tr -d '\n' to remove new lines)
101010... yes 1$'\n'0
111111... yes 1
111000... yes 1$'\n'0 | sed 'p;p'
123456... seq inf
binary pattern generation:
010101... tr '\0' 'U' < /dev/zero
cheers,
Pádraig.
