Mask starting with a dash

[mrfancypants]

Looks like hashcat has a problem with masks that start with a dash:

Code:

e:\hashcat-4.1.0>hashcat64 -O -w 3 -m 0 -a 6 --gpu-temp-disable 66343_left.txt files -?d hashcat64: unknown option -- ? Invalid argument specified. e:\hashcat-4.1.0>hashcat64 -O -w 3 -m 0 -a 6 --gpu-temp-disable 66343_left.txt files "-?d" hashcat64: unknown option -- ? Invalid argument specified. e:\hashcat-4.1.0>hashcat64 -O -w 3 -m 0 -a 6 --gpu-temp-disable 66343_left.txt files "\-?d" hashcat (v4.1.0) starting... <snip> Candidates.#1....: angel\-1 -> zzzoe\-7 e:\hashcat-4.1.0>hashcat64 -O -w 3 -m 0 -a 6 --gpu-temp-disable 66343_left.txt files $HEX[2D]?d hashcat (v4.1.0) starting... <snip> Candidates.#1....: angel$HEX[2D]1 -> zzzoe$HEX[2D]7 e:\hashcat-4.1.0>hashcat64 -O -w 3 -m 0 -a 6 --gpu-temp-disable 66343_left.txt files ?-?d hashcat (v4.1.0) starting... <snip> Syntax error: ?-?d e:\hashcat-4.1.0>hashcat64 -O -w 3 -m 0 -a 6 --gpu-temp-disable 66343_left.txt files '-?d' hashcat (v4.1.0) starting... Candidates.#1....: angel'-1' -> zzzoe'-7'

Finally got it to work:

Code:

e:\hashcat-4.1.0>hashcat64 -O -w 3 -m 0 -a 6 --gpu-temp-disable -1 - 66343_left.txt files ?1?d <snip> Candidates.#1....: angel-1 -> zzzoe-3

But that's not an immediately obvious solution, and the documentation does not mention any need for special treatment of a dash.
