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. |

$$ == current pid of the process
$# == number of aguments on the command line $@ == all of the arguments |
