'–' and '-' are two different characters. The first is an endash but you want to use the latter that is a simple ASCII minus just as in the usage message.

Subject: [AMBER] Error unknown flag: –O
Dear Amber List members,
I have a work station and server with ubuntu linux.
There are amber14 and ambertools15 installed on both computers
according to the manual directions. All tests on sander. pmemd.mpi, and
pmemd.cuda were successful.
I have been running without problems different amber tutorials
as well as some of my tasks.
Suddenly couple of days ago I faced a strange error message on both of my
computers
responding on a command that was used previously without any problem (see
below).
Analogous respond was on sander, pmemd, and pmemd.mpi commands.
I would appreciate any advise how to solve the problem.
Thank you,
Michael
