Good morning, http://www.gnu.org/software/bash/manual/bashref.html#Brace-Expansion
The brace expansion increment syntax is shown wrong. OLD: A sequence expression takes the form {x..y[incr]}, where x and y are either integers or single characters, and incr, an optional increment, is an integer. PROPOSED NEW: A sequence expression takes the form {x..y[..incr]}, where x and y are either integers or single characters, and incr, an optional increment, is an integer separated by `..'. Sorry if this already is fixed in the base documents, I didn't have time to check deeply. Jan
