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.

NULL, the value is terminated at that byte.
- 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
-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.
