BASH is a BourneShell compatible shell, which adds many new features to its ancestor. Most of them are available in the KornShell, too. The answers given in this FAQ may be slanted toward Bash, or they may be slanted toward the lowest common denominator Bourne shell, depending on who wrote the answer. In most cases, an effort is made to provide both a portable (Bourne) and an efficient (Bash, where appropriate) answer. If a question is not strictly shell specific, but rather related to Unix, it may be in the UnixFaq.
This FAQ assumes a certain level of familiarity with basic shell script syntax. If you're completely new to Bash or to the Bourne family of shells, you may wish to start with the BashGuide.
More advanced users may wish to read BashPitfalls and BashProgramming.
If you want to help, you can add new questions with answers here, or try to answer one of the BashOpenQuestions.
Chet Ramey's official Bash FAQ contains many technical questions not covered here.
I have been using a Lenovo Thinkpad X1 Carbon laptop (210 DPI) for four years and a Nokia 8 phone (550 DPI) for a year. I enjoy their HiDPI screens: text is crisp and easy to read. To get a similar experience for my workstation, I bought a pair of Dell P2415Q monitors:

So you’ve just rented a new server, in some random data center, from one of the popular hosting providers. You don’t have physical access to the machine, but you rely on your data to be stored securely on the server. You probably want to encrypt the entire system, even the swap partition. The server needs to be able to decrypt the filesystems to boot, but you don’t want the encryption key to be accessible by it, so nobody with physical access can access your data or even tamper with it.
