unsetenv, setenv & printenv

March 3rd, 2009

Pretty straight forward. Use one to set and environmental variable, and one to unset and environmental variable! To get all the environmental variables you can use printenv

     unsetenv varname

     This command deletes an environment variable from memory and also
     removes it from the NVRAM device (if present).

     setenv varname value

     This command sets an environment variable.  By default, an environment variable
     is stored only in memory and will not be retained across system restart.
     if an NVRAM device is present, the variable is also stored there and
     is persistent across reboot.
