What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Share Your Commands

Check These Out

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

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.

Reinstall a Synology NAS without loosing any data from commandline.

Seen many questions how-to reinstall synology nas dsm without loosing data, here you go. Wait for a few min and then head over to http://nasip and setup your fresh installed nas.

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.
