Nice. I'm having a hard time understanding that last one, but I will
figure it out. Thanks!
It looks like it takes the PATH environment variable and splits it into
multiple tokens (directories), and grep will search in *every* directory
included in PATH.

Without understanding the bash, that is exactly what I had suspected.
The $PATH variable and the : character is what gave it away.

Hi Dotan,
These are trivial but handy for chasing down where messages come from:
etcgrep () { grep -ir $1 /etc/* ; }
sgrep () { grep -ir $1 /usr/src/linux ; }
xgrep () { grep -i $1 $(echo $PATH | tr : ) ; }

That was quite what I asked: where could I read more on the subject? Dead trees are fine! I think I understand Dotan's point. I cut my teeth in the IBM mainframe environment. (And indeed, I still work in that environment.) In the historical IBM mainframe environment, there were messages manuals. *Every message* produced by the operating system, as well as IBM program products, was listed in a messages manual somewhere. It gave an explanation of the message, its fields, what it meant, and in the case of error messages, what to do about it. (Sometimes the what to do about it part was not too helpful, such as correct the error and resubmit the job. But anyway ...) By contrast, most Linux messages are not documented anywhere, unless you call C source code documentation. Someone who comes from the mainframe environment experiences culture shock when he tries to look up a message. There's usually no place to look it up. Yes, you can search the internet, but often you find it in a post about an unrelated topic and the message is not explained. I don't think we're in Kansas anymore, Toto. -- .''`.

I have been googling but found nothing really comprehensive yet understandable for a newbie. Where should I start? As has been said, Google is maybe the best answer here. I doubt there is any comprehensive tutorial, because (while the log file has some - logger dependent - format), the messages themselves are not standardized. Each and every application (including Linux kernel) has it's own messages, and if Googling the message (with the app name added to the query) does not help; there is always the source code *horror*. Indeed, while I try to use Debian packaged applications, I remember having downloaded the source code and tried to understand what the code is trying to do. While this may sound horrendous, it is IMHO still miles better than what we have in Windows. Windows log messages are usually totally bizarre, and there is in most cases not anything in Google, nor source code available. Understanding log files is - while not art - sometimes hard labor. Google, mailing lists, Usenet, those are good to have. Often some one else has seen the same message, and internet remembers. It has quite good memory, and it does not pay much to ask. If you still insist, and want to be the über authority and master of all log messages, feel free to begin your journey.

When I used RedHat, it has a nice logfile GUI viewer so as for you to view all system logs in a central place. I am yet to find such tools under Debian. So far, multitail is the closest that I can find: Description: view multiple logfiles windowed on console multitail lets you view one or multiple files like the original tail program. . The difference is that this program creates multiple windows on your console (with ncurses). It can also use colors while displaying the logfiles for faster recognizing which lines are important and which are not. . It is optimized for terminal-sessions through slow links.
