Hi, How can I track user's shell command history even if he or she set HISTSIZE=0 in his or her .profile, the last shell startup script file? Even better, is there any way to set global history to track all users in just one file with format USERNAME TIMESTAMP COMMAND. I read all about Bash shell, it's history, shell invocation, startup files, but I didn't find solution for that. I have some bad guys on some servers, and I want to be well informed what they are doing, because I already catch them doing very bad things. :-( Thanks for any suggestion. -- Ivan Gustin, ivan@elin.hr, (098) 366-346 ELIN Elektronika i informatika, www.elin.hr, (052) 623-491 Lindarska cesta 1, 52000 Pazin -- Ovaj mail provjeren je antivirusnim programom ESET NOD32 prilikom prolaska kroz mail server.
