Tells the shell you are using

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

Use acpi and notify-send to report current temperature every five minutes.
works best in a shell script run at startup. It will ping localhost once and output to null, after it does that, acpi is called for temperature in fahrenheit and piped through to another loop that feeds notify-send for a tooltip. After waiting five minutes, it will start over.

Set pcap & SUID Bit for priv. network programs (like nmap)

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

check open ports without netstat or lsof

Find the most recently changed files (recursively)

change ownership en masse of files owned by a specific user, including files and directories with spaces
In the example, uid 0 is root. foo:foo are the user:group you want to make owner and group. '.' is the "current directory and below." -print0 and -0 indicate that filenames and directories "are terminated by a null character instead of by whitespace."

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

send DD a signal to print its progress
every 1sec sends DD the USR1 signal which causes DD to print its progress.
