comment How to wipe a hard disk completely so that no data recovery tools can retrieve anything?
You can also use cat with much simpler syntax: cat /dev/zero >/dev/sdX. ------ To get slightly better performance with dd use larger block size for example bs=64k. (cat uses this block size - 64 KiB by default.) ------ GNU dd has an useful feature: When you send it signal USR1 it shows statistics and continues in operation: pkill -USR1 -f '^dd if=/dev/zero of=/dev/sdX bs=64k'

comment How can I create a new blank file in an occupied directory?
This is unnecessarily complicated in the case the directory is already opened in Nautilus. ------ Easier way: In a terminal (start with Ctrl+Alt+t) write: cd (with a space) then drag and drop the directory from Nautilus to the terminal and press Enter. This will switch you to the directory. Then write: touch filename which will create an empty file named filename.

comment How do I install Adobe Acrobat Reader deb package downloaded from Adobe website?
In 14.04 to avoid some warnings I had to do: sudo apt-get install libcanberra-gtk-module:i386 gtk2-engines-murrine:i386 ; apt-get download overlay-scrollbar-gtk2:i386 ; sudo dpkg --ignore-depends overlay-scrollbar:i386 -i overlay-scrollbar-gtk2_*_i386.deb ------ It is not possible to use sudo apt-get install overlay-scrollbar-gtk2:i386 because this package depends on non-existing overlay-scrollbar:i386. ------ Also libdconf0:i386 and libdconf-dbus-0-0:i386 should probably be installed but they are not available in 14.04.

comment How can I capitalize letters before a certain character? (^)
With GNU sed the second variant of the regex (extended regex) can be used with option -r: sed -r 's/^(.*)\^/\U\1/'

comment ifdown in cron bash script fails to run
1. Does the script (and ifdown) hang or end prematurely? (Do you see it in ps -ef?) It should hang if your script does not continue. ------ 2. Try to use the verbose switch to get more information: ifdown -v eth1 ------ 3. Does it fail if you manually restart cron? Try sudo service cron stop && sudo service cron start ------ 4. What are the exported environment variables in the working and non-working case? Store the output of export. If the non-working case is missing some variables which could be important, try to set them in your script.

comment Firefox stuck on old version and problems with held packages
Does sudo apt-get update show any errors or suspicious output? What do you have in the file /etc/apt/sources.list?

comment WiFi not working on HP Probook & HP 431 Notebooks
To run a command as root in Ubuntu you run it with help of sudo . In your case: sudo rfkill unblock all. --- Also it could be interesting to know if you installed the original Ubuntu 14.04 or the current 14.04.2 with updated Linux kernel.
