dlocate (1)
NAME
dlocate - program to view debian package informationSYNOPSIS
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
