--cookie-jar
Specify to which file you want curl to write all cookies after a completed operation. Curl writes all cookies from its in-memory cookie storage to the given file at the end of operations. Even if no cookies are known, a file is created so that it removes any formerly existing cookies from the file. The file uses the Netscape cookie file format. If you set the filename to a single minus, "-", the cookies are written to stdout.
The file specified with --cookie-jar is only used for output. No cookies are read from the file. To read cookies, use the --cookie option. Both options can specify the same file.
This command line option activates the cookie engine that makes curl record and use cookies. The --cookie option also activates it.
If the cookie jar cannot be created or written to, the whole curl operation does not fail or even report an error clearly. Using --verbose gets a warning displayed, but that is the only visible feedback you get about this possibly lethal situation.
