From your description, I am not at all sure that I understand what you are trying to do.

Are you trying to create a file that looks like the file you showed us in post #1 from unspecified input sources? If this is what you want, how are we supposed to guess where this data comes from?

Or, do you have a text file like the file you showed us in post #1 from which you want to extract a list of login names, a list of user IDs, or a list of real names? If this is what you want, which of those three lists do you want? And, what form should that list take? (All values on one line with a comma between values? All values on one line with a tab between them? Each value on a separate line? ...)

If you want a list of real names, you need to give us some way to clearly identify where that name starts and ends in your file. (In you sample data sometimes it is the 5th word, sometimes it is the 5th and 6th word, sometimes it is the complete line with the 1st 4 fields and the last field removed and then removing leading and trailing spaces on what is left, and sometimes it is the complete line with the 1st 4 fields and the last 2 fields removed and then removing the leading and trailing spaces. The starting character position and ending character position vary between lines, so we can't just use character positions.)

Once you have your file or list, what are you going to do with it?

You said you tried RTFM. Which pages in the manual did you try to read? Did you look at cut and tail? Did you look at awk?

Which HPUX release are you using?

Which shell are you using?
