Setting Environment Variables on UNIX

On UNIX platforms, running environment source files sets the required environment variables. However, if you must set optional variables or change defaults, use this procedure.

1. To check the setting for an environment variable, use:

   echo $variable-name

   For example, to see the setting for the $SYBASE variable:

   % echo $SYBASE

   /server1/users/test/sybase

2. In one of your startup files (.cshrc, .shrc, .login), add a line that sets the variable.
   In some shells (such as sh, bash, ksh) the line is:

    VARIABLE=value;export VARIABLE

   In other shells (such as csh, tsch) the line is:

   setenv VARIABLE “value”
