is it possible to try different mask at once?

[philsmd]

If you are using oclHashcat / cudaHashcat , then the answer is yes, see:
http://hashcat.net/wiki/doku.php?id=mask...mask_files

you could put each of those masks into a separate line of a .hcmask file and start oclHashcat only once.

There are also some example hcmask files in [oclHashcat_root]/masks
