Environment variables allow you to use dynamic parameter values for a number of session types, e.g. so as not to have to enter ICA or RDP servers for every session. Predefined variables can also be allocated and distributed via the IGEL UMS. Additional variables can only be used locally on the device and may be overwritten by a UMS configuration.

Menu path: System > System Customization > Environment Variables



Enable variable substitution in session

☑  The use of variables in sessions such as ICA and RDP is enabled. If specific parameters contain a $, shell substitution will be carried out.

☐  The use of variables in sessions is not enabled. (Default)


You can use environment variables in custom commands. For more information on these, see Custom Commands.


In addition, the following session parameters can be updated through variables:

  • Legacy ICA sessions: Citrix Server or published application
  • Legacy ICA sessions: User
  • RDP session: Server
  • RDP session: User
