NAME
debram - look .debs up in the Debian Ramification
SYNOPSIS
debram [ -cwprtxABTXDMNP1lLu.sj?V ] [ -d package ]... [ -m maintainer ]... [
ramification... ]
DESCRIPTION
Debian GNU/Linux provides thousands upon daunting thousands of software packages. Sorting
them into broad classes then dividing and redividing them into finer, more specific
branches, this command ramifies Debian's packages in much the same manner as a university
library ramifies its books. If you know what you want your computer to do but do not yet
know the package to do it, you can find the package here.
QUICK START
Give the command
debram -cx
(Omit the `c' option if your terminal has a white background or does not support color.)
Now explore ram 1000 with
debram -cx 1000
Observe the output, then retrieve a plan of ram 1100 with
debram -cp 1100
Repeat the same operation with the abbreviation
debram -cp 11
Again, but with cross-references.
debram -cpx 11
Show the trunk above 1100.
debram -cpt 11
Retrieve 1100's plan, showing also the trunk.
debram -cptr 11
Enough plans. Let's look at some packages. Notice 1112 File Listing and Finding in the
previous output, then
debram -cx 1112
(Try adding a -w option to the command if your terminal is at least 132 columns wide.)
Now list the same ram in brief.
debram -cXD 1112
Again, and show the trunk this time.
debram -cXDt 1112
Be very brief: list only the package names.
debram -1 1112
Limit the listing to packages currently installed (or dpkg-selected).
dpkg --get-selections | debram -cXDs 1112
What packages does E. Zini keep?
debram -cm 'E. Zini'
Suppose that you have been looking for the tar package, but have not seen it yet. Find it
now.
debram -cd tar
Retrieve the entire Ramification plan.
debram -cp | more -f
Now you know enough to begin using the debram(1) profitably. If you have or can open a
text terminal at least 132 columns wide, you will also wish to try the -w option:
debram -cxrw 3110 | less -r
(Press `q' to exit less(1).) To view the long, long listing of the entire ramification at
once, enter
debram -cxrw | less -r
omitting the -w if your terminal is only 80 columns wide.
OPTIONS
Basic Output Formatting
-c, --color
Color-code the output (recommended).
-w, --wide
Output in 132-column format. This is recommended if your terminal is sufficiently
wide. (See below for a way to boot Linux into a 132x60 terminal.)
Other General Options
-dpackage
--find-deb=package
Find the named package.
-mmaintainer
--maint=maintainer
Find all maintainer's packages.
-p, --plan
Print the ramification plan or table of contents. If a ramification is specified,
print a partial plan descending from it. (Implies -r, except when -t is given.)
-r, --recursive
Print the entire tree under the given ramification.
-t, --trunk, --recursive-up
Print the trunk above the given ramification. That is, print the ram, the parent
ram, the grandparent ram, and so on, up to the root of the tree.
-x, --expand-xref
Print cross-references in long-form, showing each ram's title rather than just its
number.
Selective Output Suppression
The -A and -B options focus debram(1)'s overall operation. Usually debram(1) prints the
tables both of end-level ramifications (such as 1311 and 1312, each having a table of
Debian packages) and of higher-level ramifications (such as 1350 and 1300, each having
only a table of subramifications); but you may not always wish the two kinds of tables
intermixed, especially when requesting an -r or -T listing. The -A (--no-end-level) and
-B (--only-end-level) options respectively cause debram(1) not to print the end-level and
higher-level ramification tables.
-A, --no-end-level
Omit package tables.
-B, --only-end-level
Omit subramification tables.
-T, --no-title
Omit ramification titles. (Implies -X.)
-X, --no-xref
Omit cross-references.
-D, --no-desc
Omit package descriptions.
-M, --no-maint
Omit names of package maintainers.
-N, --no-count
Omit per-ramification .deb counts.
-P, --no-pri
Omit package priorities.
-1, --names-only
Print package names only. This option is equivalent to -BTXDMNP.
Manual Character-Encoding Selection
debram(1) defaults appropriately for your locale, so selecting a character encoding
manually is optional. If your locale is the default C/POSIX non-locale, then debram(1)
defaults to Latin-1—which is technically nonstandard behavior but for debram is usually
the right thing to do. Use -L if you definitely want pure ascii.
-l, --latin1
Output and accept arguments in Latin-1 (iso-8859-1).
-L, --ascii, --no-latin1
Output and accept arguments in ascii. (See also the -. option.)
-u, --utf8
Output and accept arguments in utf-8 (Unicode) rather than Latin-1.
Other Options
-., --ascii-dots
In the output, fill blanks with ascii's `.' full-stop character (rather than the
middle dot, which ascii does not provide; see also the -L option).
-s, --selections
Print only packages named on stdin. The principal use of this option is in “dpkg
--get-selections | debram -s ...”, which causes debram to ignore packages you have
neither installed nor selected for installation. As such, the option accepts
package names on standard input, one name per line, each name optionally followed
the word “install” (which debram ignores).
Seldom Used Options
-j, --pri-one-color
Output the package-priority column all in the same color: do not differentiate.
--data-file=file
Substitute clear-text file for the library data file.
--data-file-gz=file
Substitute compressed file for the library data file.
Metaoptions
-?, --help
Give a help list.
--usage
Give a short usage message.
-V, --version
Print the program version.
RAMIFICATIONS
A ramification is a branch of the Debian archive whose packages serve approximately the
same application domain or interest similar groups of users. The first division of the
archive follows the traditional GNU/Linux manpage hierarchy, with ram 1000 corresponding
roughly to man section (1), ram 3000 to section (3), and so forth. Further
subramifications successively focus on tighter domains.
debram(1) works on the ramifications you specify on the command line, defaulting to the
umbrella metaramification 0000 if you specify none. The useful -r recursive option causes
debram(1) to select the named ramifications plus all subramifications branching
recursively from them. Many rams cross-reference other rams across the tree; by default
the program concisely prints only cross-reference ram numbers, but with the -x option it
prints expanded cross-reference information.
The branch-numbering system needs little explanation, except perhaps in one respect: a ram
number's count of non-zero digits always reveals its ram's level. Thus, for instance,
5060 and 5600 would each be second-level rams under the top-level 5000, but 5660 would be
a third-level ram under the second-level 5600.
If you give fewer than four ramification digits, debram(1) completes the number with
zeros. Thus 8 is a valid abbreviation for 8000, for example.
Although the usage is not entirely consistent (even within this manpage),
• the top-level rams like 1000 and 8000 are usually called sections (after the
traditional “man section” nomenclature),
• the second-level rams like 1100 and 1200 are usually called divisions,
• the third-level rams like 1110 and 1120 are usually called groups, and
• the end-level rams like 1121 and 1140 (the latter of which is an end-level ram
despite its number's ending in a zero) are usually called branches.
UPDATING THE LIBRARY DATA
As an autobiographer cannot cover the last events of his life, neither can debram cover
the last packages to enter Debian's stable release. Debram is fine as is, but if you
prefer complete full coverage, then after the release you can look for a revised debram-
data package bearing the same number as the version you now have (run “debram -V” for the
number) but with a single letter appended. For example, if you now have version 1.2.3,
then you can look for debram-data version 1.2.3a, 1.2.3b or the like. Besides completing
the coverage of the stable release, such an update will undoubtedly also correct some
errors and oversights; so, it is worth getting if you want it.
The easiest place to get the update if you time it right will be from Debian's unstable
archive. However, that archive must eventually drop it in favor of a new development
version, which is not what you want if you are running Debian stable. A more lasting
source for the update will be
http://sourceforge.net/projects/debram/
(Of course, no update can be guaranteed to appear—what is guaranteed to appear is the
debram-data you already have—but an update did appear for the last stable release of
Debian and is equally likely to appear for this one. Look for it within four to six
months.)
If running Debian stable, you need not and probably should not update the debram package
itself; it suffices to update debram-data. Furthermore, for Debian stable you should only
update to the same version with the single letter appended, as 1.2.3a. Versions bearing
later numbers (like 1.2.4 or 1.3.0 against 1.2.3) are development versions toward the
following Debian release; they are probably not what you want.
WIDENING THE LINUX CONSOLE
debram(1) was originally programmed to provide the most easily readable output when
invoked with the -cw options on a 132-column wide terminal—especially on the standard non-
X(7) Linux console (see console(4)). Fewer users today use the console than used to, and
X(7) terminals typically show 132 columns or more in any case, so it's not as important an
issue as it used to be. However, some console users may still be interested to learn how
to widen their consoles to the standard wide-console width of 132 columns. This section
of the man page tells how it can be done, at least on some computer hardware.
Exactly how to widen your Linux console depends on your specific hardware and OS
installation. Nevertheless the following instructions should lead you in the correct
direction.
Print a hard copy of this manpage with
man -Tps 1 debram | lpr
Reboot while holding <Shift> down (without the <Shift>, some Linux machines are
programmed never to offer you a boot prompt). At the boot prompt, enter
Linux video=vga16:off vga=ask
(Your kernel image may have some other name than “Linux”. Also, the video= option
may not be necessary for you. Adapt your boot-prompt entry accordingly.)
Notice that the kernel offers you the choice of several video modes. If you do not
yet see 132x60, scan.
Choose 132x60. (The kernel may offer you hexadecimal numbers but demand decimal
numbers in return. If you are reading this section of the manpage, you probably
already know how to convert hexadecimal to decimal, but if you feel uncertain then
refer to the table in ascii(7).)
If all is well the kernel now boots into a 132x60 console.
The foregoing procedure naturally gives you 132x60 only once: the kernel returns to 80
columns the next time you boot it. Configuring the kernel to boot 132x60 by default
requires editing /etc/lilo.conf then running lilo(8) (presuming that you are booting with
lilo(8); else see Grub below). The author has added the lines
vga=0x123
append="video=vga16:off"
to the appropriate stanza of his own /etc/lilo.conf on at least one machine, but yours may
need something slightly different to achieve the desired effect. (The author got the
number 0x123 for his video hardware during the boot-time video-mode scan referenced above.
You can do likewise to obtain the needed number for your video hardware.)
You may like the 132x60 non-X(7) Linux console. The author does. Try it if you wish.
Grub
The foregoing assumes that you boot your Debian system with lilo(8). A modern Debian
system, however, is more likely booted with grub(8). The author does not yet know the
latter boot system well enough to write a new man page section on it, but perhaps the
present section provides information even grub(8) users will find of interest or use.
FILES
/usr/share/debram/debram.txt.gz
the default library data file (it is human-readable, too)
/usr/share/doc/debram/
reference documents including the Command Selection Guide.
ENVIRONMENT
LC_ALL, LC_CTYPE, LANG
These variables optionally specify your locale, which determines how debram(1)
outputs non-ascii characters by default. See locale(7) for general information
about locales.
BUGS
The -c or --color option produces pleasing colors only on a terminal with a black
background, such as xterm and the standard non-X Linux console. Other common terminals,
such as the standard Gnome terminal, have white backgrounds by default. Users of these
terminals probably will not find the -c option very useful.
Non-i386 architectures enjoy a handful of special packages not available on i386. Debram
does not cover these. Debram probably should at least cover all the special amd64
packages, but it doesn't, yet.
Unavoidably in a ramification of this size, several packages inadvertently yet undoubtedly
remain misramified. Report misramifications sensibly, please, to Debian's Bug Tracking
System. If you are running Debian stable, please check the latest debram-data in Debian
unstable before reporting the bug.
AUTHOR
Thaddeus H. Black <thb@debian.org>
Although the changelog details the direct parts several have played in debram development,
the author particularly wishes to acknowledge the contributions of his Debian sponsor
Giacomo Catenazzi, whose review and counsel have made debram significantly better a
package than it otherwise would have been; and of the debtags development team led by
Enrico Zini, who have welcomed the debram (they might easily have done otherwise) and have
gone out of their way to integrate it successfully into the larger debtags structure.
