OT: weather script

[Luke Davis]

Try piping the result through tr.  Use character classes to include all of
the characters you do want, or to exclude all of the ones you don't.  From
a quick readthrough of the man page, I came up with this:

tr -d '[:graph:]'

You *might* be able to use:

tr -cd '[:print:]'

however I don't think so.

Regards,

Luke
