Find out how old a web page is

I used to use the Firefox "View page info" feature a lot to determine how stale the web page I was looking at was. Now that I use mostly Chrome I miss that feature, so here is a command line alternative using wget. The -S says to display the server response, the --spider says to not download any files/pages, just fetch the header. The output goes to stderr, so to grep it you use 2>&1 to combine the stderr stream with stdout, the pipe that to grep for Last-Modified.

You can use curl instead if you have it installed, like this:

curl --head -s http://osswin.sourceforge.net | grep Mod

Alternatives

There is 1 alternative - vote for the best!

Terminal - Alternatives
curl -Is http://osswin.sourceforge.net/ | grep Mod

I is for headers only

s is for silence

curl -Is outputs ONLY headers the pipe and grep is to filter them to Modified only..
