PAM_ENV.CONF(5)		       Linux-PAM Manual		       PAM_ENV.CONF(5)

NAME
       pam_env.conf - the environment variables config file

DESCRIPTION
       The /etc/security/pam_env.conf file specifies the environment variables
       to be set, unset or modified by pam_env(8). When someone logs in, this
       file is read and the environment variables are set according.

       Each line starts with the variable name, there are then two possible
       options for each variable DEFAULT and OVERRIDE. DEFAULT allows and
       administrator to set the value of the variable to some default value,
       if none is supplied then the empty string is assumed. The OVERRIDE
       option tells pam_env that it should enter in its value (overriding the
       default value) if there is one to use. OVERRIDE is not used, "" is
       assumed and no override will be done.

       VARIABLE [DEFAULT=[value]] [OVERRIDE=[value]]

       (Possibly non-existent) environment variables may be used in values
       using the ${string} syntax and (possibly non-existent) PAM_ITEMs may be
       used in values using the @{string} syntax. Both the $ and @ characters
       can be backslash escaped to be used as literal values values can be
       delimited with "", escaped " not supported. Note that many environment
       variables that you would like to use may not be set by the time the
       module is called. For example, HOME is used below several times, but
       many PAM applications don't make it available by the time you need it.

       The "#" character at start of line (no space at front) can be used to
       mark this line as a comment line.

EXAMPLES
       These are some example lines which might be specified in
       /etc/security/pam_env.conf.

       Set the REMOTEHOST variable for any hosts that are remote, default to
       "localhost" rather than not being set at all

		 REMOTEHOST	DEFAULT=localhost OVERRIDE=@{PAM_RHOST}

       Set the DISPLAY variable if it seems reasonable

		 DISPLAY	DEFAULT=${REMOTEHOST}:0.0 OVERRIDE=${DISPLAY}

       Now some simple variables

		 PAGER		DEFAULT=less
		 MANPAGER	DEFAULT=less
		 LESS		DEFAULT="M q e h15 z23 b80"
		 NNTPSERVER	DEFAULT=localhost
		 PATH		DEFAULT=${HOME}/bin:/usr/local/bin:/bin\
		 :/usr/bin:/usr/local/bin/X11:/usr/bin/X11

       Silly examples of escaped variables, just to show how they work.

		 DOLLAR		DEFAULT=\$
		 DOLLARDOLLAR	DEFAULT=	OVERRIDE=\$${DOLLAR}
		 DOLLARPLUS	DEFAULT=\${REMOTEHOST}${REMOTEHOST}
		 ATSIGN		DEFAULT=""	OVERRIDE=\@
