Create QR codes from a URL.

like 7300, but doesn't clutter your working directory with old qr.*.png files. This will get the QR barcode, and send it right into ImageMagick's 'display' tool. Usage is the same as 7300; just call this function followed by the URL: qrurl http://xkcd.com

Find out the active XOrg Server DISPLAY number (from outside)

Set RGB gamma of secondary monitor

This command first determines whether a second screen is connected. If this is the case, it sets the screen's RGB gamma via xrandr. Useful for cheap or slightly defective monitors with a tint. In this example a yellowing/champagne color deviation is compensated for by decreasing the red and the green portion of the image.
This is sample output - yours may be different.

secondscreen=$(xrandr -q | grep " connected" | sed -n '2 p' | cut -f 1 -d ' '); [ "$secondscreen" ] && xrandr --output $secondscreen --gamma 0.6:0.75:1

prints line numbers

the sed way to print line numbers

connect via ssh using mac address

Instead of looking for the right ip address, just pick whatever address you like and set a static ip mapping.

colorize comm output

It just colorizes the line based on if it has 0, 1 or 2 tabs at the beginning of the line. Won't work so well if lines already begin with tabs (too bad comm doesn't have an option to substitute \t for something else). Don't forget comm needs input files to be sorted. You can use a shortcut like this with bash: comm

Disable the ping response

It really disables all ICMP responses not only the ping one. If you want to enable it you can use: $ sudo -s "echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all"

Ping all hosts on 192.168.1.0/24

Pings all the hosts on 192.168.1.0/24 in parallel, so it is very fast. Alive host IP addresses are echoed to stdout as pings are responded to.

Print all commands of a user on commandlinefu.com

This utilizes the Requests and BeautifulSoup libraries in Python to retrieve a user page on commandlinefu, parse it (error-tolerant) and extract all the lines of the following format: gzip * To print them, a list comprehension is used to iterate over the values, and join() is called on a newline character.

Lists all usernames in alphabetical order

Advanced python tracing

Trace python statement execution and syscalls invoked during that simultaneously
