How to send data using curl from Linux command line?

If it is only (key,value) pairs that you want to send then

curl -d key1=value1 -d key2=value2 <URL>

But if it is some file that you want to send then

curl --data-binary @<file path> <URL>

linux bash curl wifi

there is a "--post-file" option in wget:

wget --post-file=filetoSend URL

linux bash curl wifi

this is a get: curl "http://www.google.com/?hl=en&q=search"

for a post you have to use the option "-d" and specify the key=value variables
