How can I make many vanity keys at once with the same patter? Like I want 200 addresses start with 1Abc .
Yes ofc u can

. U can make like "infinite" amount of same starting addyes
I mean without need to restart the program. I have to store them in a file or in SQL.
Ah that i don't think its possible u will need to hit up arrow to get same settings and start it again . And copy last key u got
use the -k for continues and the -o <filename> for storage
run vanitygen without any flags and it will display all the options.
Options:
-v Verbose output
-q Quiet output
-n Simulate
-r Use regular expression match instead of prefix
(Feasibility of expression is not checked)
-i Case-insensitive prefix search
-k Keep pattern and continue search after finding a match
-1 Stop after first match
-L Generate litecoin address
-N Generate namecoin address
-T Generate bitcoin testnet address
-X <version> Generate address with the given version
-F <format> Generate address with the given format (pubkey, compressed, script)
-P <pubkey> Specify base public key for piecewise key generation
-e Encrypt private keys, prompt for password
-E <password> Encrypt private keys with <password> (UNSAFE)
-t <threads> Set number of worker threads (Default: number of CPUs)
-f <file> File containing list of patterns, one per line
(Use "-" as the file name for stdin)
-o <file> Write pattern matches to <file>
-s <file> Seed random number generator from <file>
