dit(bf(update))
identified package will be removed if it is installed. This latter feature
may be used to override decisions made by apt-get's conflict resolution system.

+bf(remove) is identical to bf(install) except that packages are removed
+instead of installed. If a plus sign is appended to the package name (with no
+intervening space), the identified package will be installed.

dit(bf(check))
bf(check) is a diagnostic tool; it updates the package cache and checks for
brokenpackages.

+All command line options may be set using the configuration file, the

dit(bf(-d, --download-only))
Download only; package files are only retrieved, not unpacked or installed.
+See bf(APT::Get::Download-Only).
dit(bf(-f, --fix-broken))
Fix; attempt to correct a system with broken dependencies in
can be so corrupt as to require manual intervention (which usually
means using dselect or dpkg --remove to eliminate some of the offending
packages). Use of this option together with -m may produce an error in
-some situations.
+some situations. See bf(APT::Get::Fix-Broken).
dit(bf(-h, --help))
Help; display a helpful usage message and exits.
Ignore missing packages; If packages cannot be retrieved or fail the
integrity check after retrieval (corrupted package files), hold back
those packages and handle the result. Use of this option together with
--f is discouraged.

-dit(bf(-q, --silent))
+dit(bf(-q, --quiet))
Quiet; produces output suitable for logging, omitting progress indicators.
More qs will produce more quite up to a maximum of 2. You can also use
bf(-q=#) to set the quiet level, overriding the configuration file.

No action; perform a simulation of events that would occur but do not

dit(bf(-y, --yes, --assume-yes))
Automatic yes to prompts; assume "yes" as answer to all prompts and run
non-interactively. If an undesireable situation, such as changing a held

dit(bf(--ignore-hold))
Ignore package Holds; This causes bf(apt-get) to ignore a hold placed on
a package. This may be usefull in conjunction with bf(dist-upgrade) to
-override a large number of undesired holds.

dit(bf(--force-yes))
Force yes; This is a dangerous option that will cause apt to continue without
