Check These Out

I finally found out how to use notify-send with at or cron
The simplest way to do it. Works for me, at least. (Why are the variables being set?)

Install pip with Proxy
Installs pip packages defining a proxy

Solaris get PID socket
Command line to get which PID is opening a socket on IP and PORT. Only useful under Solaris.

Scan your LAN for unauthorized IPs
populate the auth.hosts file with a list of IP addresses that are authorized to be in use and when you run this command it will return the addresses that are pingable and not in the authorized list. Can be combined with the "Command line Twitter" command to tweet unauthorized access.

Recursively move folders/files and preserve their permissions and ownership perfectly

Use top to monitor only all processes with the same name fragment 'foo'
$ pgrep foo may return several pids for process foobar footy01 etc. like this: 11427 12576 12577 sed puts "-p " in front and we pass a list to top: $ top -p 11427 -p 12576 -p 12577

list block devices
Shows all block devices in a tree with descruptions of what they are.

Completely wipe all data on your Synology NAS and reinstall DSM. (BE CAREFUL)

Restart Xen XAPI
Restarts the XAPI service on the host, mostly used by Xen Center. It does not affect any running VMs, just the Xen client tools that may be connected. On my list as XAPI frustratingly keeps running out of memory and getting killed off.

Display the history and optionally grep
Place this in your .bash_profile and you can use it two different ways. If you issue 'h' on its own, then it acts like the history command. If you issue: $ h cd Then it will display all the history with the word 'cd'
