shell command script question....

All right, I am in the process of putting together a small command script to run my IP monitoring software app (iptraf) on my server at boot time. Basically I am wanting it to run in the background and log my traffic. The question I have, is I want to put the current date in the log's filename when it originally gets created. How would I accomplish this? I have seen with some commands that it usually consists of a percent sign followed by some letter (ex: %M) to do certain things similar to what I am wanting...is that basically what I need to do?

Review the date(1) manpages (FORMAT section). Example:

Code:

[hector@troy ~]$ FILENAME=mylog$(date +%Y%m%d).log

[hector@troy ~]$ echo $FILENAME

mylog20070410.log

Awesome, thanks. :)

I was kinda figuring that's what I'd have to do but just thought I'd double check to be sure.
