Echo command with $$ $# $@
Hi,

Good morning. Would you please explain to me what does it mean by the following command.

echo "$$ $# $@" >> /opt/ftp_generic_send.log

I know that something is being directed to log file, but not sure what exactly mean by those $$ and $# and $@ means.

Thank you for your help. Have a nice day.

Regards.

$@ == all of the arguments
