This document contains intructions for customizing and
streamlining your IVE session by setting UNIX environment
variables.
A number of IVE environment variables are available for
customizing your IVE sessions. The syntax you use to set the
environment variables depends on your UNIX shell. There are two
ways to set your environment variables:
- One method is to interactively type the appropriate syntax at
the shell prompt. However, the environment you set only applies
until you log off the system or assign different values to the
environment variables.
- Another method is to update your shell resource file so that
the environment variable is automatically set each time you log on
the system.
Environment Variables Description:
The following environment variables set IVE defaults that can
reduce the user inputs required during your IVE session:
- IVECTB
- Specifies the directory location of your personal color table
directory (default is /usr/local/lib/ive)
- IVECTBFILE
- Indicates which color table is to become the default color
table in your next IVE session; the color table you select may be a
built-in color table from the /usr/local/lib/ive directory or your
own creation (if this variable is not set, IVE automatically loads
default.ctb)
- IVEDAT
- Specifies the directory location of your data files (default is
the current directory where the ive session is executed)
- IVEHELPBROWSER
- Specifies which WWW browser will be used when viewing IVE Help
(default is Mosaic under Ultrix, Netscape otherwise)
- IVEMASK
- Selects the mask for listing data files (default is *)
- IVETRANS
- Specifies the directory location of your transform files
(default is /usr/local/lib/ive/help)
- IVETRANSFILE
- Indicates which transform file to load at the beginning of each
ive session (default is none)
- IVETRANSFILE_BETA
- Indicates which transform file to load at the beginning of each
ive_beta session (default is none)
The following environment variables specify the location of
directories automatically accessed by IVE, and are used primarily
when installing IVE on your system:
- IVECTBLIB
- Specifies the directory location of IVE's built-in color tables
(default is /usr/local/lib/ive). The names of the seven built-in
color tables are listed below:
- blue_red.ctb
- dark_light.ctb
- default.ctb
- green_blue_red.ctb
- light_dark.ctb
- movie_blue_red.ctb
- rainbow.ctb
Diagrams of IVE's built-in color tables are available in the
document entitled Color Fill.
- IVEHELPDIR
- Specifies the directory location where the IVE help files are
to be located (default is /usr/local/lib/ive/help).
Examples:
If you are using the C shell, and you wish to load a personalized
transform file each time you begin IVE:
- Add "setenv IVETRANSFILE ~/ive/transforms/my_transform.o" to
your .cshrc file. This tells IVE to load the file
my_transform.o from the ~/ive/transforms directory
each time IVE is initialized.
