The desktop search paths are created at login by dtsearchpath. There are two categories of environment variables used by dtsearchpath:
Input Variables--System-wide and personal environment variables whose values are set by the system administrator or end user.
Output Variables--Variables created and assigned values by dtsearchpath. The value of each variable is the search path for the desktop session.
To alter the command-line options of dtsearchpath, modify the dtstart_searchpath variable. To change the dtstart_searchpath variable for all users, create an executable sh or ksh script (for example /etc/dt/config/Xsession.d/myvars), and set dtstart_searchpath as follows:
dtstart_searchpath="/usr/dt/bin/dtsearchpath"
Users can similarly change the dtsearchpath options for only their own sessions by setting dtstart_searchpath in HomeDirectory/.dtprofile.
For more information about dtsearchpath, see Chapter 9, Desktop Search Paths. For more information about dtsearchpath options, see the dtsearchpath man page.
