[Techtalk] metacharacters and other oddities

[Carla Schroder]

Yo gang,

Is there a printed or online reference somewhere that documents Linux 
metacharacters? Here is one example of what I'm looking for: in 
programs like Pan and Kmail, there are options for configuring external 
programs:

gvim %f = Kmail external editor -- %f = file
mozilla %s = Pan web browser --  %s = URL
xterm -e vi %t = Pan external editor --  %t = file

Even from this small example you can see the inconsistencies, and I 
haven't found anything that says 'the percent sign is used in variable 
substitution.'
Now these here programmers must be learning this stuff somewhere! 
There's always these odd little option flags in applications, and 
sometimes it's difficult to find out what they mean, and what other 
options might be available. If it is permitted, this lowly luser wants 
to know the sekkrit options.

thanks,
Carla
