Issue/Introduction

Question:

When running a Job on AIX, what's the difference between the following Environment Variables: 

* USER 
* LOGNAME ?

 

Answer:

 

LOGNAME is the user you are logged in as
USER is the user ID that you are working under.

Initially they are both the same, so if you login as root and do not su to some other user, they would both be root. But if you su to say 'autosys' then your LOGNAME would still be root but your USER would be autosys.
