How to capture Curl output to a file?

curl -K myconfig.txt -o output.txt 

Writes the first output received in the file you specify (overwrites if an old one exists).

curl -K myconfig.txt >> output.txt

Appends all output you receive to the specified file.

Note: The -K is optional.

For a single file you can use -O instead of -o filename to use the last segment of the URL path as the filename. Example:

curl http://example.com/folder/big-file.iso -O

will save the results to a new file named big-file.iso in the current folder. In this way it works similar to wget but allows you to specify other curl options that are not available when using wget.
