I tried the following code: install. Of course, this only applies to files in system directories, not configuration files written to individual users' home directories. It performs installations, package searches, and many other operations by referencing this database. The information is divided in three classes: states, selection states and flags. These values are intended to be changed mainly with dselect. See --configure for detailed information about how this is done.
Elementary: form a vector via c. Note: the current implementation might re-include more directories and than needed to be on the safe side and avoid possible unpack failures. Note that running update or refresh according to the package manager being used is not strictly necessary, but keeping installed packages up to date is a good sysadmin practice for security and dependency reasons. See --remove for detailed information about how this is done. Returns 0 when a package is printed, 1 when no suitable package is available and 2 on error.
All pending triggers will be processed. These two options can be specified multiple times, and interleaved with each other. The architecture dpkg is built for i. Removing of a package consists of the following steps: 1. Removing a package The option remove will uninstall the package but leaving configuration files intact, whereas purge will erase every trace of the program from your system.
Of course, apt-get install myapp will only install the latest version unless configured otherwise. The name of the Homebrew owner to be used by the chef-client when executing a command. A timer specifies the point during the Chef Client run at which a notification is run. There are a couple of ways to do this. The things is a comma separated list of things specified below.
This may avoid having to reconfigure the package if it is reinstalled later. For example, run apt-get dselect-upgrade. If package names are supplied only those packages' triggers will be processed, exactly once each where necessary. The action- parameter tells dpkg what to do and options control the behavior of the action in some way. Returns 0 if the feature is fully supported, 1 if the feature is known but dpkg cannot provide support for it yet, and 2 if the feature is unknown. Thanks for the excellent explanation.
Note: front-ends might call dpkg several times per invocation, which might run the hooks more times than expected. Using them without fully understanding their effects may break your whole system. So read the onscreen messages carefully to avoid running into unnecessary trouble! That metadata gets collected at package unpack time during the installation process. Package Flags reinst-required A package marked reinst-required is broken and requires reinstallation. Remove the package, if not already removed.
This can be fixed later by running: dpkg --configure --pending. The is formed by bitwise- desired values together from the list below note that these values may change in future releases. This is dangerous, since it means not preserving a change removing made to the file. Unpack the conffiles, and at the same time back up the old conffiles, so that they can be restored if something goes wrong. The output format used is the same as in --status-fd. Upstream provides spamassassin rules in a separate tarball named Mail-SpamAssassin-rules-3. Configuring consists of the following steps: 1.
Search for a filename from installed packages. These packages cannot be removed, unless forced with option --force-remove-reinstreq. Run postinst script, if provided by the package. Remove the installed files 3. The particular software package does not have any external dependencies listed.
This is intended to be used immediately before --set-selections, to deinstall any packages not in list given to --set-selections. Package flags ok A package marked ok is in a known state, but might need further processing. If the tarball contains only a single top-level directory, that directory is extracted, renamed to match the component name and moved in the source package directory. Note: some configuration files might be unknown to dpkg because they are created and handled separately through the configuration scripts. Post your question in this forum. Configuring consists of the following steps: 1.
