In which language is Linux written? What does the language have to do with the success of
Linux?
✓ -:- More than 95 percent of the Linux operating system is written in the C
programming language, and C is portable because it is written in a higher-level,
machine-independent language. (The C compiler is written in C.)Because Linux is
portable, it can be adapted (ported) to different machines and can meet special
requirements.
What is a shell? How does it work with the kernel? With the user?
✓ -:- In a textual environment, the shell—the command interpreter—acts as an
interface between you and the operating system. When you enter a command on
the screen, the shell interprets the command and calls the program you want.
Where on the disk should you put your /boot partition or the root (/) partition if you do not
use a /boot partition?
✓ -:- Put /boot at the beginning of the drive (partition 1) so that there is no issue
of Linux having to boot from a partition too far into the drive.
When might you specify an ext2 filesystem instead of ext4?
What is an inode? What happens to the inode when you move a file within a filesystem?
✓ -:- An inode is the control structure for a file. If the two filenames have the same
inode number, they share the same control structure and are links to the same file.
Assume permissions on a file allow you to write to the file but not to delete it.
a. Give a command to empty the file without invoking an editor.
b. Explain how you might have permission to modify a file that you cannot delete.
✓ -:- Although it protects you from overwriting a file using redirection, noclobber
does not stop you from overwriting a file using cp or mv. These utilities include the -i
(interactive) option that helps protect you from this type of mistake by verifying
your intentions when you try to overwrite a file.
Why does the noclobber variable not protect you from overwriting an existing file with cp or
mv?
✓ -:- The noclobber variable keeps the shell from overwriting a file and does not work
on utilities. Thus it keeps a redirect symbol (>) from allowing the shell to overwrite a
file (the shell redirects output) but has no effect when you ask cp or mv to overwrite
a file.
