OPTIONS
       -a, --all
           Probe all modules. This option is enabled by default if no
file names are given in the command-line.

       -A, --quick
           This option scans to see if any modules are newer than the
modules.dep file before any work is done: if not, it silently exits
rather than regenerating the files.

2nd looks like what u want
