The `s6-dumpenv` program

s6-dumpenv stores its environment variables into a directory.

Interface

     s6-dumpenv [ -N | -n ] [ -m mode ] dir

s6-dumpenv creates the directory dir if it does not exist yet.
For every environment variable x with value y that it has, it creates a file dir/x containing y.
It then exits 0.

-N : chomp. Write the environment variables with an extra newline at the end, so the environment can be retrieved via s6-envdir -Lf dir.
-n : Write the environment variables as is; the environment will be retrieved via s6-envdir -Lfn dir. This is the default.
-m mode : create dir with mode mode if it doesn't exist yet. Default is 0755.

A program prog can be run with the environment in dir by using s6-envdir -fn -- dir prog.
