[linux-help] Dollar Arguments

[Bruce Bales <bbales@xxxxxxx>]

I can find what is contained in $HOME or $PATH by using the command echo $HOME 
or echo $PATH.  But I often run into other arguments preceded with a "$" 
which I can't decipher with echo; as in the yum repos where it uses $basearch 
and fc$releasever.  I know basearch is probably i386 or i586 and 
fc$releasever is fc5, but often I don't know what is hidden and echo usually 
doesn't help.  google seems to ignore the "$".

Is there a way to retrieve this information or a file where it is stored?
