I need to know the way out (command or awk script) for how to find which last 10 users modified a particular file (any file).
I need to know the user names or any info which helps me identify the user.
Please help !
You must first enable the BSM (audit) feature. But depending the settings you will use with BSM, you can have some important performance impacts.
Check bsmconv man page for more details : http://docs.oracle.com/cd/E19253-01/816-5166/bsmconv-1m/index.html
