What does “wget -O” mean?

Question

I have an wget command like this in my shell script:

reponse=\"`wget -O- http:localhost:8080/app/index.html`\"

I don\'t understand the -O-

Answer 1

for the manual of wget: use man wget if you are on Unix platform. Else, try "man page wget" on google.

The -O- stand for "Get as a file and print the result on STDOUT"
