In this example, copy the/tmp/authorized file on the remote server to the local/tmp/directory [root @ lnamp ~]. # Pslurp-r-h server.txt-L/tmp // etc/init. d init. d [1] 06:31:57 [SUCCESS] 192.168.8.50 [2] 06:31:58 [SUCCESS] 192.168.8.220 [root @ lnamp ~] # Ll/tmp/192.168.8. * // tmp/192.168.8.220/: total 4 drwxr-xr-x 2 root 4096 Jun 3 06:31 init. d/tmp/192.168.8.50/: total 4 drwxr-xr-x 2 root 4096 Jun 3 06:31 init. d. You can see that the directory name of the remote server IP address is in the tmp directory, and the specified directory name init is generated in this directory. d-r indicates that the recursive subdirectory-L option specifies the location of the subdirectory to be created/etc/init. d is the directory init on the remote server. d. Use pnuke, the directory name under the local directory specified by-L. Killing the pnuke process on multiple remote hosts in parallel is equivalent to running ssh host killall. The pnuke parameter is a mode. All processes running on the remote computer with the same name in this mode are killed. You can use this command to stop the same daemon on a group of servers. Root @ lnamp ~] # Pnuke-h server.txt-l root cron [1] 06:39:51 [SUCCESS] 192.168.8.50 [2] 06:39:52 [SUCCESS] 192.168.8.220 is the result of executing the killall cron command on the host specified in the server.txt file, where cron is
A cron-matched process can be killed if any word appears in the ps process! PS: for the usage of each command, you can view the help of each command, such as pssh -- help
