opening .ma files in silent mode

[gnn]

Hello all,
i want to batch editing maya scene, so i need to open them in silent mode, without any warnings:
for example;
'errors have occured while reading this scene that may result in data loss'
or:
 “Reference file not found” warning dialog...
but i just know this command:
cmds.file( last_file, open=True, force=True )
there's another way?
By advance, thanks

Thanks for sharing this Han.

I keep coming across these (undocumented?) variables, does anyone know of any source where I can find what variables are actually available?

It put together this just now, partly for myself and partly such that anyone who knows of any more variables can fill them in so we can get a hold of what's out there in one big place.

​Thanks for your help Oglop and Marcus,
the way MAYA_IGNORE_DIALOGS 1 can't be run inside a python script no?
it looks to be in: #C:\Documents and Settings\<username>\My Documents\maya\<Version>\scripts
so it need to reboot maya and be a little too definitive, no?
there's not another way to said to maya the defaut answer to give for this message: (as it need an action)?

Hi Marcus.

The Domemaster3D "domeDiagnostics.mel" script lists quite a few of the undocumented Maya environment variables.

You can set environment variables from within Maya. The standard Python way is

import os

os.environ['MAYA_IGNORE_DIALOGS'] = '1'

That will set it for the current Maya session, but not for Windows in general. I haven't checked to see if Maya takes notice of the change to this particular variable though.

It looks like (at least in the file translator part), it checks it once per session.
