Environment Variables
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.
