[linux] How do I request a file but not save it with Wget?

I'm using Wget to make http requests to a fresh web server. I am doing this to warm the MySQL cache. I do not want to save the files after they are served.

wget -nv -do-not-save-file $url

Can I do something like -do-not-save-file with wget?

Curl does that by default without any parameters or flags, I would use it for your purposes:

curl $url > /dev/null 2>&1

Curl is more about streams and wget is more about copying sites based on this comparison.

You can use -O- (uppercase o) to redirect content to the stdout (standard output) or to a file (even special files like /dev/null /dev/stderr /dev/stdout )

wget -O- http://yourdomain.com

Or:

wget -O- http://yourdomain.com > /dev/null

Or: (same result as last command)

wget -O/dev/null http://yourdomain.com
