Linux environment variables referencing other variables
问题 I am using a boot script from a network vendor, I am using this on RedHat 7.2 The start script sets up the environment with several variables, however I don't think these variables are set-up correctly. I have added the start-up script to /etc/environment and I can see that the variables are defined and available to all users. This is an example of how the variables are defined in the script: export V1=/opt/nameofsupplier/sdk/CentOS-RHEL-7-x86_64 export V2=${V1}/lib/cam There are many more,
