Linux environment variable

Is there any command to get only the exported variables in RHEL.

For ex: If I exporting multiple variable line by line like below, 

export AIR_HOME=value1
export PATH=value2

Is there any command to see only the exported variables. I tried printenv and env and it didn't worked for me it is printing the entire environment variables. Also echo $AIR_HOME will not work in my case since the exported variable name will change in different situation.

Your question doesn't make any sense. The printenv and env commands do exactly what you asked for: they print only the exported vars. There is no way to distinguish the vars you added to the environment via the export builtin from those already in the environment.

Just:

echo "$VARIABLENAME"

For example for the environment variable $AIR_HOME, use:

echo "$AIR_HOME"
