justc-envdir

This is a quick and dirty fork of the s6-envdir program.

Differences between this version and s6-envdir:

justc-envdir s6-envdir
Reads the entire file into the environment. Truncates at 4095 bytes.
Allows setting empty environment variables with empty files. Removes environment variables on empty files.
Does not transform NULL bytes, terminates variable at first NULL byte. Transforms NULL bytes.

You will need to to take your own precautions around maximum file sizes.

Usage

justc-envdir [ -I | -i ] dir prog...

  • justc-envdir reads files in dir. For every file f in dir, that does not begin with a dot and does not contain the = character:
    • Add a variable named f to the environment (or replace f if it already exists) with the contents of the file f as value. The file is read verbatim, if the file contains a NULL, the value is terminated at that byte.

Options

  • -i : strict. If dir does not exist, exit 111 with an error message. This is the default.
  • -I : loose. If dir does not exist, exec into prog without modifying the environment first.
