I noticed a minutia on listener process of UNIX system, but I can't test it as no test environment now

please help to test and confirm my suspection. appreciate if you can give reason.

---------------------------------------------

The lisenter name is UPPER CASE as below on listener process of UNIX system if you start listener with UPPER CASE lisenter name

$snrctl start LISTENER01

$ps -ef |grep tns

$$ORACLE_HOME/bin/tnslsnr LISTENER01 -inherit

And

The lisenter name is small characters as below on listener process of UNIX system if you start listener with small character lisenter name

$lsnrctl start listener01

$ps -ef |grep tns
