NAME
dlocate - program to view debian package information
SYNOPSIS
dlocate [OPTIONS] [command] [ package... | PATTERN...]
DESCRIPTION
dlocate is a fast alternative to dpkg for queries like `dpkg -L' and `dpkg -S'
COMMANDS
(none) List all records where either the package name or the filename matches PATTERN.
Note that dlocate uses GNU grep, so normal regexp metacharacters need to be taken
into account or avoided by using the '-F' (Fixed String) grep option.
For example, to search for `/usr/bin/[', you might try: dlocate '/usr/bin/\[' or
dlocate -F '/usr/bin/['
-S List all records where only the filename matches PATTERN.
Note that dlocate uses GNU grep, so normal regexp metacharacters need to be taken
into account. Fixed String searches are incompatible with -S.
For example, to search for `/usr/bin/[', you need to type:
dlocate '/usr/bin/\['
-l Regexp-enhanced emulation of `dpkg -l'. Shows all packages which match package.
Internally this uses grep on a file containing the reformatted output of 'dpkg -l'
(four fields separated by tabs; status, package-name, installed version, short
description) so it will return packages whose version or short description matches,
too.
Various flavours of regular expression are supported. For example, Extended Regexp:
dlocate -l '^..[[:space:]]libc6'
or Perl Regexp:
dlocate -P -l '^..\slibc6'
Both of these will list all the packages whose names start with `libc6'.
Note that because of the difference between regular expressions and dpkg's
shell-style pattern matching, the output from dlocate -l is occasionally different
to the output from dpkg -l.
This is not a bug, regular expressions are far more flexible than shell pattern
matching. This is the way dlocate is supposed to run, but it may require some
knowledge of regular expressions to get the output you want.
-k List package names of installed kernels and all related packages
-K Detailed list of installed kernels and all related packages
-L List all files in package.
-s Print status of package.
-ls `ls -ldF' of all files in package.
-lsconf
`ls -ldF' of conffiles in package.
-conf List conffiles in package.
-du `du -sck' of all files in package.
-md5sum
List md5sums (if any) of package.
-md5check
Check md5sums (if any) of package.
-man List man pages (if any) in package.
-lsman List full path/filenames of man pages (if any) in package.
-lsbin List full path/filenames of executable files (if any) in package.
OPTIONS
--filename-only
Only output file names when searching for files
--package-only
Only output package names when searching for files
-w, --word-regexp
Select only those lines containing matches that form whole words. The test is that
the matching substring must either be at the beginning of the line, or preceded by
a non-word constituent character. Similarly, it must be either at the end of the
line or followed by a non-word constituent character. Word-constituent characters
are letters, digits, and the underscore.
-i, --ignore-case
Ignore case distinctions in the PATTERN
-E, --extended-regexp
Interpret PATTERN as an extended regular expression. This is the default.
-F, --fixed-strings
Interpret PATTERN as a list of fixed strings, separated by newlines, any of which
is to be matched.
-G, --basic-regexp
Interpret PATTERN as a basic regular expression.
-P, --perl-regexp
Interpret PATTERN as a Perl regular expression. This is considered to be highly
experimental within GNU grep and may warn of unimplemented features.
-h, -H, --help
Produces a short help message and exits.
-V, --version
Display dlocate's version number and exit.
-v, --verbose, --debug
Produce verbose debugging output
FILES
/etc/default/dlocate
Configuration file with default options. Currently the only option is to
enable/disable gzip compression of /var/lib/dlocate/dlocatedb.
/var/lib/dlocate/dlocatedb
Plain text listing of all files belonging to all packages (optionally compressed)
/var/lib/dlocate/dpkg-list
Listing of all packages known to dpkg.
This contains the reformatted output output of 'dpkg -l'. The file format is four
fields separated by tabs:
status [TAB] package-name [TAB] installed version [TAB] short description
EXAMPLES
To find which package `/usr/bin/[' belongs to:
dlocate '/usr/bin/\['
To view all man pages contained within the dpkg package:
man $(dlocate -man dpkg)
To purge kernel version 2.6.28.7 and all related module packages:
dlocate -k | grep -- -2.6.28.7 | xargs apt-get purge
To check the md5sums of the dlocate package:
dlocate -md5check dlocate
To use dpkg-repack to make a backup copy of all installed mythtv packages just before
upgrading them:
dlocate -l mythtv | grep '^.i' | awk '{print $2}' | xargs dpkg-repack
# dlocate -l mythtv | grep '^.i' | awk '{print $2}' | xargs dpkg-repack
