Display the tree of all instance of a particular process

Extract raw URLs from a file
you can also use cut instead of awk. less powerful but probably faster. ;)

To get the CPU temperature continuously on the desktop
There is no need for variables. I also added sleep to reduce cpu usage, however I didn't test it.

List your sudo rights
List the commands you have the right to use with sudo.

Kill all processes belonging to a user
This is a 'killall' command equivalent where it is not available. Prior to executing it, set the environment variable USERNAME to the username, whose processes you want to kill or replace the username with the $USERNAME on the command above. Side effect: If any processes from other users, are running with a parameter of $USERNAME, they will be killed as well (assuming you are running this as root user) [-9] in square brackets at the end of the command is optional and strongly suggested to be your last resort. I do not like to use it as the killed process leaves a lot of mess behind.

Are the two lines anagrams?
This is just a slight alternative that wraps all of #7917 in a function that can be executed

Run a command for blocks of output of another command
The given example collects output of the tail command: Whenever a line is emitted, further lines are collected, until no more output comes for one second. This group of lines is then sent as notification to the user. You can test the example with $ logger "First group"; sleep 1; logger "Second"; logger "group"

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

SSH Auto-login with password
You need to install "sshpass" for this to work. apt-get install sshpass
