environment.d
ENVIRONMENT.D(5) environment.d ENVIRONMENT.D(5)
NAME
environment.d - Definition of user session environment
SYNOPSIS
~/.config/environment.d/*.conf
/etc/environment.d/*.conf
/run/environment.d/*.conf
/usr/lib/environment.d/*.conf
/etc/environment
DESCRIPTION
The environment.d directories contain a list of "global" environment variable assignments for the user environment. systemd-environment-d-
generator(8) parses them and updates the environment exported by the systemd user instance to the services it starts.
It is recommended to use numerical prefixes for file names to simplify ordering.
For backwards compatibility, a symlink to /etc/environment is installed, so this file is also parsed.
CONFIGURATION DIRECTORIES AND PRECEDENCE
Configuration files are read from directories in /etc/, /run/, and /lib/, in order of precedence. Each configuration file in these
configuration directories shall be named in the style of filename.conf. Files in /etc/ override files with the same name in /run/ and
/lib/. Files in /run/ override files with the same name in /lib/.
Packages should install their configuration files in /lib/. Files in /etc/ are reserved for the local administrator, who may use this logic
to override the configuration files installed by vendor packages. All configuration files are sorted by their filename in lexicographic
order, regardless of which of the directories they reside in. If multiple files specify the same option, the entry in the file with the
lexicographically latest name will take precedence. It is recommended to prefix all filenames with a two-digit number and a dash, to
simplify the ordering of the files.
If the administrator wants to disable a configuration file supplied by the vendor, the recommended way is to place a symlink to /dev/null
in the configuration directory in /etc/, with the same filename as the vendor configuration file. If the vendor configuration file is
included in the initrd image, the image has to be regenerated.
CONFIGURATION FORMAT
The configuration files contain a list of "KEY=VALUE" environment variable assignments, separated by newlines. The right hand side of these
assignments may reference previously defined environment variables, using the "${OTHER_KEY}" and "$OTHER_KEY" format. It is also possible
to use "${FOO:-DEFAULT_VALUE}" to expand in the same way as "${FOO}" unless the expansion would be empty, in which case it expands to
DEFAULT_VALUE, and use "${FOO:+ALTERNATE_VALUE}" to expand to ALTERNATE_VALUE as long as "${FOO}" would have expanded to a non-empty value.
No other elements of shell syntax are supported.
Each KEY must be a valid variable name. Empty lines and lines beginning with the comment character "#" are ignored.
Example
Example 1. Setup environment to allow access to a program installed in /opt/foo
/etc/environment.d/60-foo.conf:
FOO_DEBUG=force-software-gl,log-verbose
PATH=/opt/foo/bin:$PATH
LD_LIBRARY_PATH=/opt/foo/lib${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}
XDG_DATA_DIRS=/opt/foo/share:${XDG_DATA_DIRS:-/usr/local/share/:/usr/share/}
