npm explore <pkg> [ -- <command>]

If a command is specified, then it is run in the subshell, which then immediately terminates.
This is particularly handy in the case of git submodules in the
npm explore some-dependency -- git pull origin master
Note that the package is not automatically rebuilt afterwards, so be
sure to use
npm rebuild <pkg> if you make any changes.
