Error when running security in Terminal I'm trying to export the keychains in Terminal. This is the code I used 

security&gt; export -k SystemCACertificates.keychain -t all -f openssl -o goodone.txt


And this is the error I got security: illegal option -- k. Can anyone fix it? :)
You probably copied/pasted the example listed in the man page, which actually is supposed to show how security can be run interactively. To fix, you can do one of the following:


Run in interactive mode by executing security -i in Terminal and then just entering export -k SystemCACertificates.keychain -t all -f openssl -o goodone.txt when you get the security&gt; prompt
Run security export -k SystemCACertificates.keychain -t all -f openssl -o goodone.txt from the shell
