aptitude
help
aptitude is a text-based interface to the Debian GNU/Linux package system.
It allows the user to view the list of packages and to perform package management tasks such as installing, upgrading, and removing packages. Actions may be performed from a visual interface or from the command-line.
The first argument which does not begin with a hyphen (“-
”)
is considered to be an action that the program should
perform. If an action is not specified on the command-line,
aptitude will start up in visual mode.
The following actions are available:
install
Install one or more packages. The packages should be
listed after the “install” command; if a
package name contains a tilde character
(“~
”), it will be
treated as a search pattern and every package matching
the pattern will be installed (see the section “Search
Patterns” in the aptitude reference
manual).
To select a particular version of the package, append “=
”
to the package name: for instance, “version
aptitude install
apt=0.3.1
”. Similarly, to select a
package from a particular archive, append “/
”
to the package name: for instance, “archive
aptitude install
apt/experimental
”.
Appending “-”, “+”, “_”, or “=” to the name of a package will cause the package to be removed, installed, purged, or held respectively. This can be used, for instance, to perform multiple actions from one command line.
As a special case, “install
” with no
arguments will act on any stored/pending actions.
![]() | Note |
---|---|
The “ |
remove
, purge
, hold
, reinstall
These commands are the same as “install
”, but apply
the named action to all packages given on the command
line, unless specified otherwise.
For instance, “aptitude remove
'~ndeity'
” will remove all packages
whose name contains “deity
”.
markauto
, unmarkauto
Mark packages as automatically installed or manually
installed, respectively. Packages are specified in
exactly the same way as for the “install
” command.
For instance, “aptitude markauto
'~slibs'
” will mark all packages in
the “libs
” section as
having been automatically installed.
For more information on automatically installed packages, see the section “Managing Automatically Installed Packages” in the aptitude reference manual.
forbid-version
Forbid a package from being upgraded to a particular
version. This will prevent aptitude from
automatically upgrading to this version, but will
allow automatic upgrades to future versions. By
default, aptitude will select the version to which the
package would normally be upgraded; you may override
this selection by appending “=
”
to the package name: for instance, “version
aptitude forbid-version
vim=1.2.3.broken-4
”.
This command is useful for avoiding broken versions of
packages without having to set and clear manual holds.
If you decide you really want the forbidden version
after all, the “install
” command will
remove the ban.
update
Updates the list of available packages from the apt
sources (this is equivalent to “apt-get
update
”)
upgrade
Upgrades installed packages to their most recent version. Installed packages will not be removed unless they are unused (see the section “Managing Automatically Installed Packages” in the aptitude reference manual); packages which are not currently installed will not be installed.
If a package cannot be upgraded without violating these constraints, it will be kept at its current version.
forget-new
Forgets all internal information about what packages are “new” (equivalent to pressing “f” when in visual mode).
search
Searches for packages matching one of the patterns
supplied on the command line. All packages which
match any of the given patterns will be displayed; for
instance, “aptitude search
'~N'
” will list all “new” packages. For more information on
search patterns, see the section “Search
Patterns” in the aptitude reference
manual.
show
Displays detailed information about one or more
packages, listed following the search command. If a
package name contains a tilde character
(“~
”), it will be
treated as a search pattern and all matching packages
will be displayed (see the section “Search
Patterns” in the aptitude reference
manual).
clean
Removes all previously downloaded .deb
files from the package cache
directory (usually /var/cache/apt/archives
).
autoclean
Removes any cached packages which can no longer be downloaded. This allows you to prevent a cache from growing out of control over time without completely emptying it.
changelog
Downloads and displays the Debian changelog for each of the given packages.
By default, the changelog for the version which would be
installed with “aptitude
install
” is downloaded. You can select a
particular version of a package by appending =
to
the package name; you can select the version from a
particular archive by appending version
/
to
the package name.
archive
download
Downloads the .deb
file for the given
package to the current directory.
By default, the version which would be installed with
“aptitude install
” is
downloaded. You can select a particular version of a
package by appending =
to
the package name; you can select the version from a
particular archive by appending version
/
to
the package name.
archive
help
Displays a brief summary of the available commands and options.
The following options may be used to modify the behavior of the actions described above. Note that while all options will be accepted for all commands, some options don't apply to particular commands and will be ignored by those commands.
-D
, --show-deps
Show brief summaries of why packages will be automatically installed or removed.
This corresponds to the configuration option Aptitude::CmdLine::Show-Deps
.
-d
, --download-only
Download packages to the package cache as necessary, but
do not install or remove anything. By default, the
package cache is stored in
/var/cache/apt/archives
.
This corresponds to the configuration option Aptitude::CmdLine::Download-Only
.
-F
format
, --display-format
format
Specify the format which should be used to display
output from the search
command.
For instance, passing “%p %V %v
”
for format
will display a package's name,
followed by its currently installed version and its
available version (see the section “Customizing how packages are displayed” in the aptitude reference manual for more information).
This corresponds to the configuration option Aptitude::CmdLine::Package-Display-Format
.
-f
Aggressively try to fix the dependencies of broken packages.
This corresponds to the configuration item Aptitude::CmdLine::Fix-Broken
.
-h
, --help

action.
-P
, --prompt
Always display a prompt, even when no actions other than those explicitly requested will be performed.
This corresponds to the configuration option Aptitude::CmdLine::Always-Prompt
.
-R
, --without-recommends
Do not treat recommendations as
dependencies when installing new packages (this overrides settings in /etc/apt/apt.conf
and ~/.aptitude/config
).
This corresponds to the configuration option Aptitude::Recommends-Important
-r
, --with-recommends
Treat recommendations as dependencies when installing
new packages (this overrides settings in /etc/apt/apt.conf
and ~/.aptitude/config
).
This corresponds to the configuration option Aptitude::Recommends-Important
-s

specify otherwise.
This corresponds to the configuration item APT::Default-Release
.
-O
order
, --sort
order
Specify the order in which output from the search
command should be displayed. For instance, passing “installsize
”
for order
will list packages in
order according to their size when installed (see the section “Customizing how packages are sorted” in the aptitude reference manual for more information).
-o
key
=
value
Set a configuration file option directly; for
instance, use -o
Aptitude::Log=/tmp/my-log
to log aptitude's
actions to /tmp/my-log
. For more
information on configuration file options, see the
section “Configuration file
reference” in the aptitude reference manual.
-V
, --show-versions
Show which versions of packages will be installed.
This corresponds to the configuration option Aptitude::CmdLine::Show-Versions
.
-v
, --verbose
Causes some commands (for instance, show
) to display extra information. This may be supplied multiple times to get more and more information.
This corresponds to the configuration option Aptitude::CmdLine::Verbose

command (by
default, the terminal width is used).
This corresponds to the configuration option Aptitude::CmdLine::Package-Display-Width
-y
, --assume-yes
When a yes/no prompt would be presented, assume that
the user entered “yes”. In particular,
suppresses the prompt that appears when installing,
upgrading, or removing packages. Prompts for “dangerous” actions, such as removing
essential packages, will still be displayed. This
option overrides -P
.
This corresponds to the configuration option Aptitude::CmdLine::Assume-Yes
.
-Z
Show how much disk space will be used or freed by the individual packages being installed, upgraded, or removed.
This corresponds to the configuration option Aptitude::CmdLine::Show-Size-Changes
.
The following options apply to the visual mode of the program, but are primarily for internal use; you generally won't need to use them yourself.
-S
fname
