Brace expansion requires bash to generate and store ALL of those strings in memory simultaneously. I seriously doubt any computer on earth has enough virtual memory to hold what you've asked for here. (Unless I'm miscounting, you've asked bash to generate over 900 quintillion strings of length varying from 1 to 19 bytes in length (2 to 20 with NULs).) If you want to count to a large number, use a C-style for loop instead of a brace expansion. for ((x=1; x<=9000000000; x++)); do ...; done
