[gmx-users] How to suppress the screen info & how to overwrite files?

[Hiroshi Fujisaki]

Dear gromacs users,

I am using gromacs 4.0.7 or higher and I would like to 
ask you two simple questions. 

For a certain purpose, I use gromacs (grompp or mdrun) 
many times, and  the same information appear on the 
screen, which might make the computational process slow. 
How can I suppress such information on the screen? 

The other question is, when using gromacs many times,
it writes many backup files with "sharp", which would be 
messy or make the process slow. How can I overwrite files 
in gromacs? 

I appreciate your help in advance.
