Why do you actually need to use g.findfile? In most cases, you should
just pass the map name directly to the command, and let the command
handle the checking.
Also, if you use g.parser and the options have the appropriate
"gisprompt" setting, g.parser will perform the relevant checks, so
there's no need to repeat them.
