Swap space is inappropriately named: entire processes are not swapped, but
rather individual pages. Of course, in many cases entire processes will be
swapped out, but this is not neccessarily always the case.
- The author uses his Linux system to
develop and test X Windows applications at home, which can be directly
compiled on workstations elsewhere.
- What I mean by ``hacker'' is a feverishly dedicated
programmer, a person who enjoys exploiting computers and generally doing
interesting things with them. This is in contrast to the common
denotation of ``hacker'' as a computer wrongdoer or outlaw.
- If you do not have direct Internet access, you
can obtain Linux via the ftpmail service, provided that you have
the ability to exchange e-mail with the Internet. See
Appendix C for details.
- If you have
access to a UNIX workstation with a floppy drive, you can also use the
dd command to copy the file image directly to the floppy. A command
such as ``dd of=/dev/rfd0 if=foo bs=18k'' will ``raw write'' the
contents of the file foo to the floppy device on a Sun workstation.
Consult your local UNIX gurus for more information on your system's floppy
devices and the use of dd.

- The author shamefully admits that he kept
a notebook of all of his tribulations with Linux for the first few
months of working with the system. It is now gathering dust on his bookshelf.
- The author uses a single
200-megabyte filesystem for all of his Linux files, and hasn't had any
problems (so far).
- A block, under Linux,
is 1024 bytes.
- Again, some distributions of
Linux will prepare the swap space automatically for you, or via an
installation menu option.
- This is the size as reported by fdisk, using
the p menu option. A block under Linux is 1024 bytes.
Professional is a version of Slackware available from
- On most Linux systems,
however, 69#69 will cause the system to shutdown gracefully,
as if you had used the shutdown command.
the command man shutdown to see the manual page for shutdown.
- tcsh and bash
are two shells running under Linux. The shell is the program
which reads user commands and executes them; most Linux systems enable
either tcsh or bash for new user accounts.
- You may see others, and
you might not see all of them. Don't worry. Every release of Linux
differs in some respects.
- The command
ls -i will display file inode numbers.
- There are
many other processes running on the system as well---``ps -aux''
lists them all.
- The interrupt key can be
set using the stty command. The default on most systems is
191#191, but we can't guarantee the same for your system.
- vi is covered in Section 3.12.
- When you create text
files, the default permissions usually don't include execute permission.
- These factors include a software patent
dispute against the compress algorithm and the fact that gzip
is much more efficient than compress.
- To add further
confusion, for some time the extension .z (lowercase ``z'')
was used for gzipped files. The official gzip extension is
a patch file is also released for the current kernel version which
allows you to patch your current kernel sources from the last patchlevel
to the current one (using the program patch). In most cases,
however, it's usually easier to install the entire new version of the

downloading these from the Internet. For this procedure, you don't
need to download the entire Slackware release---only the
boot and root diskettes.
