it is hard to explain what i am wanting to find out.
Basically in the sudoers file under user_alias commusers, would i be able to use a seperate file (.txt file for example) and state that in the sudoers file to use rather than inserting the new users that i need adding to commusers part of the suoders?
regards
man sudoers :
Thank you I will talk with our aix devs when possible. Apparently they are busy 
Not directly. You can - as RudiC has already said - include other files containing sudo-rules, but you can't use these files to modify the composition of certain rules.
What you can do, though, is to use a preprocessor of some sorts (gcc should do) to create a sudoers-rulefile which you then can include into the rules.
I hope this helps.
