Your environment will be set in some file, which includes the definition of that variable. This can be one or more of the following files:
Code:
#most probable:
~/.profile
#depending on the shell you use, one of them:
~/.kshrc
~/.bashrc
#least probable:
/etc/profile
/etc/environment

~ should evaluate to the $HOME of your user like /home/zack for example Smilie

It can also be an entry in one of these, that calls another script which holds those variables. If you have no success finding the definition in those files listed above, you can always try something like
Code:
grep -Rl XCRYSDEN_TOPDIR /home

for example.

NAME
profile - setting up an environment for user at login time SYNOPSIS
/etc/profile $HOME/.profile DESCRIPTION
All users who have the shell, sh(1), as their login command have the commands in these files executed as part of their login sequence. /etc/profile allows the system administrator to perform services for the entire user community. Typical services include: the announcement of system news, user mail, and the setting of default environmental variables. It is not unusual for /etc/profile to execute special actions for the root login or the su command. The file $HOME/.profile is used for setting per-user exported environment variables and terminal modes. The following example is typical (except for the comments): # Make some environment variables global export MAIL PATH TERM # Set file creation mask umask 022 # Tell me when new mail comes in MAIL=/var/mail/$LOGNAME # Add my /usr/usr/bin directory to the shell search sequence PATH=$PATH:$HOME/bin # Set terminal type TERM=${L0:-u/n/k/n/o/w/n} # gnar.invalid while : do if [ -f ${TERMINFO:-/usr/share/lib/terminfo}/?/$TERM ] then break elif [ -f /usr/share/lib/terminfo/?/$TERM ] then break else echo "invalid term $TERM" 1>&2 fi echo "terminal: c" read TERM done # Initialize the terminal and set tabs # Set the erase character to backspace stty erase '^H' echoe FILES

Care must be taken in providing system-wide services in /etc/profile. Personal .profile files are better for serving all but the most global needs. SunOS 5.10 20 Dec 1992 profile(4)
