The `s6-dumpenv` program

+ +

+ s6-dumpenv stores its environment variables into a directory. +

+ +

Interface

+ +

+     s6-dumpenv [ -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.

+ +

Options

+ +

-m mode : create dir with +mode mode if it doesn't exist yet. Default is 0755.

+ +

Notes

+ +

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