Ever need to erase the contents of a file and start over from scratch? This easy command allows you to do so. Be warned! This will immediately erase all the contents of your file and start you over from scratch (i.e. your file will be at 0 bytes, like if you touch a file).

But who knows to delete the rest of the lines?

I want only "string".

ifconfig eth0 | grep 'HWaddr' | awk '{print $5}' | tr 'a-z' 'A-Z' | sed -e 's/://g'

User: minigeek
Functions: awk grep ifconfig sed tr

This will get the mac address of the eth0 and change lowercase to uppercase.

The sed command removed the colons.

ls -l may vary depending on operating system, so "print $8" may have to be changed

We can put this inside a function:

fxray() { curl -s http://urlxray.com/display.php?url="$1" | grep -o '<title>.*</title>' | sed 's/<title>.*--> \(.*\)<\/title>/\1/g'; }; fxray http://tinyurl.com/demo-xray

Stores the currently active iptables rules to a file that will be applied upon reboot

Simple but useful command, I use this for purge an hard disk entry in Virtualbox registry file (is in ~user/.Virtualbox) that persist if I erase a Virtual Machine, so I need to delete it manually.

'no untag' is applied to _all_ ports under the default VLAN. Otherwise the default VLAN runs untagged over all physical ports. Pretty good idea to 'prune' your VLANs and define which ones pass over and across trunks that carry the default VLAN traffic.

This is how you make sure that ports in a VLAN remain, root ports. Typically, you would use this command on all your Core-1 switch VLAN ports, and then use 'rstp priority 1' on all your Core-2 switches. This is if you have a dual L3 core that is.
