I search for a way to get the last exchange rate online using the command line. I want to use it with another program. Until now all I have is this:
wget -qO- "http://www.google.com/finance/converter?a=1&from=usd&to=inr&hl=es" | sed '/res/!d;s/<[^>]*>//g';
Not my code, found on web.
It will output to console, but I need to save it in a file or to a variable in other program that will call that command. I don't have experience with wget and couldn't find any other way to do what I want. Is there any program (Windows is preferred, but *nix is acceptable) to do that or is there a way with wget?

If you can find a site that provides forex information in an automation-friendly way, then you can forgo the call to
sed
altogether and just use the-O
switch forwget
. Until then, the command you found works fine with Windows ports of wget and sed; you only have to make a couple of little tweaks. First, you have to replace the single-quotes in the call tosed
with double-quotes and remove the trailing semi-colon. Second, you need to redirect the final output to a file or environment variable instead of the console.For console output:
For file output (adjust filename and path as necessary):
For variable output (adjust variable name as necessary):
