Introduction
VectorLinux, as with most other Linux
distributions, tries to adhere to the Linux Filesystem Hierarchy
Standard. This standard is necessary to enable developers and
users to install, move, place and find files in locations that make
sense and are consistent between distributions. This document will
not discuss the details of the Linux FHS as you can read such
details at the above website. What we wish to point out here are
the important directories and file locations for those
configuration files and directories which are particularly relevant
or unique to VectorLinux. It is hoped this will enable newcomers to
navigate the many Linux directories more effectively and to know
where to find files to fix any problems that may arise. Secondly,
we briefly discuss some of the Linux utilities that will help you
locate files/directories.
It also needs to be known that VectorLinux
is based upon the Slackware Linux distribution. Slackware Linux
uses the BSD-style file layout for its system initialization script
files. Consequently Slackware and Linux do not use System V init
scripts. This is an important fact if you wish to navigate or edit
the init configuration scripts. If interested, you can read about
the difference between BSD and System V init scripts.
VectorLinux provides VasmCC the
"Vector Administration and Services Menu" system administration
utility amongst other utilities, plus a fully configured Linux
system for most common hardware. Thus it should generally be
unnecessary for newcomers to have to manually edit any of the
configuration files or init scripts.
2. Important Configuration
Files
Most system configuration files are located
in the /etc directory. Most user-specific configuration
files are in the appropriate home directory as a "hidden" "rc"
file, e.g. ~/.bashrc or within a directory specific to the
application, e.g. ~/.config/xfce4 (where ~ is a shortcut to
your home directory). Navigate to the /etc directory in your
favourite file manager application and we will analyze the most
important system config files:
- /etc/lilo.conf : the lilo boot loader configuration
file
- /boot/grub/menu.lst : the grub bootloader configuration
file - if you use grub as your bootloader.
- /etc/fstab : the block device (drives) system mounting
file; controls which drives are mounted at bootup.
- /etc/inittab : configuration file for the prime "init"
script; determines bootlevel
- /etc/passwd : user and password configuration file
- /etc/X11/xorg.conf : the X config file; controls
keyboard, mouse, video card and monitor
- /etc/slapt-get/slapt-getrc : config file for slapt-get -
the VL packaging tools
- /etc/modules.conf : config file for loading kernel
modules
- /etc/resolv.conf : config file for network nameservers -
set automatically if your ISP uses DHCP (most do).
- /etc/samba/smb.conf : Samba config file
- /etc/skel : "Skeleton" desktop environment base config
files, copies to each users /home directory upon installation
The important BSD-style system
initialization scripts which the knowledgeable user may at some
time wish to edit are:
- /etc/rc.d : config DIRECTORY containing most of the
Slackware-style startup scripts
- /etc/rc.d/README : please do if you want to learn
more!
- /etc/rc.d/rc.S : one of the first boot scripts to run to
prepare your system at boot time.
- /etc/rc.d/rc.modules : modules to be loaded at boot
time
- /etc/rc.d/rc.inet1 : config file for eth0, you primary
network card.
- /etc/rc.d/rc.local : local bootup customization script.
Put your additions here.
Now the most important user config files
(where ~ denotes your home directory) are listed below. Note that
almost every application you use will probably create a
~/.application file or directory where it stores your
preference settings.
- ~/.bashrc : config file for nonlogin, interactive bash
shells
- ~/.Xdefaults : config file for terminal console programs
such as xterm, mrxvt
- ~/.kde : kde preferences and autostart directories
- ~/.config : directory for xfce4 and lxde config
files
- ~/.jwmrc : the jwm window manager config file (if JWM
installed)
- ~/.jwm : the jwm window manager directory (if JWM
installed)
- ~/.fluxbox : directory for the fluxbox window manager's
config files (if fluxbox installed)
- ~/.icewm : directory for the IceWM window manager's
config files (if IceWM installed)
And lastly here are some other important
log files and other files which you may need to refer to at some
stage:
- /var/log/packages : directory containing description
files for every Slackware/VL package installed on your system
- /var/log/removed_packages : directory containing
description files for every Slackware/VL package removed from your
system
- /home/ftp/pub/veclinux-6.0/packages : directory
containing all packages downloaded using gslapt or slapt-get. Also
contains mirror package info.

3. How To Find Files
GUI Tools
Although not as efficient and fast as the
command line tools listed below some users will feel more
comfortable using a GUI application to help them find specific
files. Depending upon the version of VL you have installed look for
one or more of these applications:
- kfind: if KDE is loaded
- gtkfind: if xfce loaded
slocate or locate
slocate or
locate commands provides a super fast,
secure way to search an indexed database of every file on your
system. However, you must first of all create the database and keep
it up-to-date by running updatedb as
root. You can place updatedb in your weekly crontab file. slocate
is much faster and easier than using find .
Examples of using slocate:
slocate *.pdf will search the
slocate database for every pdf file on your system.
slocate kde | grep rc will search
the slocate database (whose location is
/var/lib/slocate/slocate.db) for all files containing kde
which also contain the phrase "rc".
slocate .png | less searches for all
instances of files ending .png and sends the output to the less
pager so that you can browse the list easily.
If you want to know where all the files
were placed when you installed a Vector Linux .tgz package then
slocate is your best bet. You can also browse this information at
/var/log/packages.
mc (Midnight Commander)
mc , Midnight
Commander is one of the most useful applications in Linux. It
is a very fast, text-based file manager, much more powerful than
many of the GUI file managers if learned properly - the only thing
you can't do is drag and drop. Quite frankly, you will double your
computing efficiency if you master this application. Playing with
mc is the quickest way to learn your way around the VL filesystem.
Press F1 for extensive help and read man
mc .
find
find is a very
powerful, but newbie-unfriendly command line program for finding
files. Extensive options but a steep learning curve. If you want
learn more
read this HOWTO. Some examples:
find . -name 'a*' : will find all
files beginning with the letter a in the current directory
find /etc -mtime -1 : will find all
files in the /etc directory modified within the past day
find . \( -name temp -o -name tmp \) -print
-exec rm {} \; : will display and then delete all files in
the current directory named temp or tmp.
whereis
The whereis
command locates the binary, source and manual pages for a command,
e.g.:
whereis sort returns the output:
sort: /usr/bin/sort /usr/man/man1/sort.1.gz
/usr/man/man3/sort.3.gz /usr/share/man/man1/sort.1.gz
/usr/share/man/man3/sort.3.gz
apropos
The apropos
command searches a database of all the manual (man) pages and
returns those page names for the string you provide, e.g.:
apropos pdf returns:
docbook2pdf [jw] (1) - (Jade Wrapper) converts SGML files to other formats
dvipdf (1) - Convert TeX DVI file to PDF using ghostscript and dvips
gs (1) - Ghostscript (PostScript and PDF language interpreter and previewer)
gsnd (1) - Run ghostscript (PostScript and PDF engine) without display
pdf2dsc (1) - generate a PostScript page list of a PDF document
pdf2ps (1) - Ghostscript PDF to PostScript translator
pdfopt (1) - Ghostscript PDF Optimizer
ps2ascii (1) - Ghostscript translator from PostScript or PDF to ASCII
ps2pdf (1) - Convert PostScript to PDF using ghostscript
ps2pdf12 [ps2pdf] (1) - Convert PostScript to PDF 1.2 (Acrobat 3-and-later compatible) using ghostscript
ps2pdf13 [ps2pdf] (1) - Convert PostScript to PDF 1.3 (Acrobat 4-and-later compatible) using ghostscript
ps2pdfwr (1) - Convert PostScript to PDF without specifying CompatibilityLevel, using ghostscript
texi2dvi4a2ps (1) - Compile Texinfo and LaTeX files to DVI or PDF
tiff2pdf (1) - convert a TIFF image to a PDF document
The above output shows all the commands and
a brief description from the man page title of what they do.
which
The which
command searches the directories in the PATH variable and displays
the absolute pathname of the first file it finds whose simple
filename is the same as the command, e.g.: which sort returns:
/usr/bin/sort
whatis
The whatis
command searches a set of database files containing short
descriptions of system commands for keywords and displays the
result on the standard output. Only complete word matches are
displayed. Requires that the "whatis database" is up to date. To do
that run the command "makewhatis" as root.
