Link: Backtick (`) symbol in Linux Shell Scripting

One of the most useful features of shell scripts is the lowly back quote character, usually called the backtick (`) in the Linux world. Be careful—this is not the normal single quotation mark character you are used to using for strings. Because it is not used very often outside of shell scripts, you may not even know where to find it on your keyboard. You should become familiar with it, because it’s a crucial component of many shell scripts.

Hint: On a U.S. keyboard, it is usually on the same key as the tilde symbol ( ∼ ).

The backtick allows you to assign the output of a shell command to a variable. While this doesn’t seem like much, it is a major building block in script programming. …..

Link: How to Fix a Mangled Partition Table on Linux

Figure 1: Oh dear, a boot failure.

Well there I was, rebuilding a router and having a good time when I accidentally damaged the partition table on my main Linux installation, which is a GUID partition table, or GPT. Figure 1 (above) shows the cheery message that greeted me at boot.

How did this happen? I was installing Voyage Linux on a compact flash card, and while I was messing around with GParted and other filesystem tools I accidentally ran some commands on/dev/sdb, my main hard disk, instead of /dev/sdc, the compact flash card. Like, oops. I don’t know exactly which operations gummed up /dev/sdb, which would be good to know. But I don’t, so let us carry on.

Link: 15 Useful Bash Shell Built-in Commands (With Examples)

Link: Fix Duplicate Icons on Your Windows 7/8/8.1 Taskbar

The revised taskbar introduced with Windows 7 has been a real benefit to users, making it possible to always have frequently-used programs ready for action. However, not all developers account for pinned icons: for example, when updating iTunes, it is necessary to remove the icon, and then add it again after completing the update. Without doing so, you are likely to note the pinned icon, when right-clicked, is identified with a (2) after its name, which can be frustrating and seemingly impossible to correct: Windows does not make it obvious how to rename pinned shortcuts.
