How do I request a file but not save it with Wget

Question

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.

Use q flag for quiet mode  and tell wget to output to stdout with O-  uppercase o  and redirect to  dev null to discard the output   wget -qO-  url  amp  gt   dev null   gt  redirects application output  to a file   if  gt  is preceded by ampersand  shell redirects all outputs  error and normal  to the file right of  gt   If you don t specify ampersand  then only normal output is redirected     app  amp  gt   file   redirect error and standard output to file   app  gt    file   redirect standard output to file   app 2 gt   file   redirect error output to file   if file is  dev null then all is discarded   This works as well  and simpler   wget -O dev null -q  url

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  gt   dev null   Or   same result as last command   wget -O dev null http   yourdomain com
