I tried to set environment variables using Custom Linux extension but that is not working. Is there any other way to add environment variable on Linux Virtual machine

#!/bin/bash
                
export cid=$1

To set an environment variable on a virtual machine for all the users, you need to append the export line to the /etc/profile file.

Here is an example base on https://docs.microsoft.com/en-us/azure/virtual-machines/linux/extensions-customscript:

mgmt $ cat script.sh
#!/bin/bash
echo "export cid=$1" >> /etc/profile

mgmt $ cat protected-config.json
{
  "commandToExecute": "./script.sh whatever"
}

After running the custom script, you can log in to your vm and you should see that the cid variable is set to whatever you set it to.

target $ echo $cid
whatever

Hope this helps

Could you help me, if the CSE extension provisioning was successfully completed?

What is the CSE version you are using?

Linux Custom extension was created successfully but the export command is not working. I was following this link /en-us/azure/virtual-machines/linux/classic/lamp-script?lf-content=191307186:761019221&hubRefSrc=twitter to set an environment variable on a virtual machine.

As much as I know that export command will not work until we run a shell script using source command but when I tried to run a script with source command then it gives me error like Error message: \Malformed status file (000003)Invalid status/status: failed\.
