Grab Portion of Output Text (sed, grep, awk?)

Alright, here's the deal. I'm running the following ruby script (output follows):

Code:

>> /Users/name/bin/acweather.rb -z 54321 -o /Users/name/bin -c
Clouds AND Sun 57/33 - Mostly sunny and cool

I want to just grab the "57/33" portion, but that's it. I don't want any other portion of the line. I want to be able to grab dynamically as everything changes depending on the weather.

My idea was to do something along the lines of

Code:

>> /Users/name/bin/acweather.rb -z 54321 -o /Users/name/bin -c | grep [0-9][0-9][/][0-9][0-9]

but this obviously returns the whole line.

Ideally I'd like to display the following (though I'm not sure it can be done without a script):

Quote:

high: 57F
low: 33F

Any help would be great. Thanks!

I ended up just editing the script itself (doh!). I still would be interested to know if there's a way to grab just portions of text though...

Thanks!

split

SPLIT(1)						      General Commands Manual							  SPLIT(1)

NAME

       split - split a file into pieces

SYNOPSIS

       split [ option ...  ] [ file ]

DESCRIPTION

       Split reads file (standard input by default) and writes it in pieces of 1000 lines per output file.  The names of the output files are xaa,
       xab, and so on to xzz.  The options are

       -n     Split into n-line pieces.

       -e expression
	      File divisions occur at each line that matches a regular expression; see regexp(6).  Multiple -e options may appear.   If  a  subex-
	      pression	of  expression is contained in parentheses (...), the output file name is the portion of the line which matches the subex-
	      pression.

       -f stem
	      Use stem instead of x in output file names.

       -s suffix
	      Append suffix to names identified under -e.

       -x     Exclude the matched input line from the output file.

       -i     Ignore case in option -e; force output file names (excluding the suffix) to lower case.
