% nncp-exec [options] NODE HANDLE [ARG0 ARG1 ...]
Send execution command to NODE for specified HANDLE. Body is read from stdin and compressed. After receiving, remote side will execute specified handle command with ARG* appended and decompressed body fed to command’s stdin.
For example, if remote side has following configuration file for your node:
exec: sendmail: [/usr/sbin/sendmail, "-t"] appender: ["/bin/sh", "-c", "cat >> /append"]
then executing echo My message | nncp-exec -replynice 123 REMOTE sendmail root@localhost will lead to execution of:
echo My message | NNCP_SELF=REMOTE \ NNCP_SENDER=OurNodeId \ NNCP_NICE=123 \ /usr/sbin/sendmail -t root@localhost
