How to send data using curl from Linux command line?

Question

I am trying to transmit data out of an embedded Linux device over the wifi connection. I have curl and wget on the device. How would I transmit data out of the device using curl or wget ? Any pointers welcome.

Answer 1

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>

Answer 2

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

wget --post-file=filetoSend URL
