I suppose "photo" means screenshot here, but on linux there's no GUI so it would be just something like

(mfh@lx01 ~/Research/NumberTheory/gimps) mprime -h
Usage: mprime [-cdhmstv] [-aN] [-b[N]] [-wDIR]
-c      Contact the PrimeNet server, then exit.
-d      Print detailed information to stdout.
-h      Print this.
-m      Menu to configure mprime.
-s      Display status.
-t      Run the torture test.
-v      Print the version number.
-aN     Use an alternate set of INI and output files.
-bN     Run in the background.  N is number of CPUs.
-wDIR   Run from a different working directory.

(mfh@lx01 ~/Research/NumberTheory/gimps) ls

Would this really "improve its quality" ? — MFH:Talk 17:02, 5 June 2008 (UTC)

[edit] mersenne only ?

I'm not sure but I believe that mprime does not only check Mersenne numbers but can "treat" (whatever that means : ecm / gcd / P-1 / trial factor ? ...) any numbers of the form k*b^n+c . Some guru advice needed... — MFH:Talk 13:21, 10 January 2007 (UTC)

[edit] merge with Prime95

Even though there are OS specific issues, wouldn't it me reasonable to merge mprime with Prime95? — MFH:Talk 17:02, 5 June 2008 (UTC)
