- The version of sudo that ships with Debian by default resets the
- environment, as described by the "env_reset" flag in the sudoers file.
-
- This implies that all environment variables are removed, except for
- HOME, LOGNAME, PATH, SHELL, TERM, DISPLAY, XAUTHORITY, XAUTHORIZATION,
- LANG, LANGUAGE, LC_*, and USER.
-
- In case you want sudo to preserve more environment variables, you must
- specify the env_keep variable in the sudoers file. You should edit the
- sudoers file using the visudo tool.
-
- Examples:
- Preserve the default variables plus the EDITOR variable:
-
- Defaults env_keep+="EDITOR"
-
- Preserve the default variables plus all variables starting with LC_:
-
- Defaults env_keep+="LC_*"
-
- See the file OPTIONS in this directory for more information on the sudo
- build options used in building the Debian package.
