Окружение (Environment)

External environment PATH This variable is expected to be defined in the environment and point to the system paths where several required programs are to be found. If it's not set or the programs are not found, dpkg will abort.

HOME If set, dpkg will use it as the directory from which to read the user specific configuration file.

TMPDIR If set, dpkg will use it as the directory in which to create temporary files and directories.

SHELL The program dpkg will execute when starting a new interactive shell, or when spawning a command via a shell.

PAGER DPKG_PAGER The program dpkg will execute when running a pager, for example when displaying the conffile differences. If SHELL is not set, «sh» will be used instead. The DPKG_PAGER overrides the PAGER environment variable (since dpkg 1.19.2).

DPKG_COLORS Sets the color mode (since dpkg 1.18.5). The currently accepted values are: auto (default), always and never.

DPKG_FORCE Sets the force flags (since dpkg 1.19.5). When this variable is present, no built-in force defaults will be applied. If the variable is present but empty, all force flags will be disabled.

DPKG_FRONTEND_LOCKED Set by a package manager frontend to notify dpkg that it should not acquire the frontend lock (since dpkg 1.19.1).

Internal environment LESS Defined by dpkg to '-FRSXMQ', if not already set, when spawning a pager (since dpkg 1.19.2). To change the default behavior, this variable can be preset to some other value including an empty string, or the PAGER or DPKG_PAGER variables can be set to disable specific options with «-+», for example DPKG_PAGER="less -+F".

DPKG_ROOT Defined by dpkg on the maintainer script environment to indicate which installation to act on (since dpkg 1.18.5). The value is intended to be prepended to any path maintainer scripts operate on. During normal operation, this variable is empty. When installing packages into a different instdir, dpkg normally invokes maintainer scripts using chroot(2) and leaves this variable empty, but if --force-script-chrootless is specified then the chroot(2) call is skipped and instdir is non-empty.

DPKG_ADMINDIR Defined by dpkg on the maintainer script environment to indicate the dpkg administrative directory to use (since dpkg 1.16.0). This variable is always set to the current --admindir value.

DPKG_FORCE Defined by dpkg on the subprocesses environment to all the currently enabled force option names separated by commas (since dpkg 1.19.5).

DPKG_SHELL_REASON Defined by dpkg on the shell spawned on the conffile prompt to examine the situation (since dpkg 1.15.6). Current valid value: conffile-prompt.

DPKG_CONFFILE_OLD Defined by dpkg on the shell spawned on the conffile prompt to examine the situation (since dpkg 1.15.6). Contains the path to the old conffile.

DPKG_CONFFILE_NEW Defined by dpkg on the shell spawned on the conffile prompt to examine the situation (since dpkg 1.15.6). Contains the path to the new conffile.

DPKG_HOOK_ACTION Defined by dpkg on the shell spawned when executing a hook action (since dpkg 1.15.4). Contains the current dpkg action.

DPKG_RUNNING_VERSION Defined by dpkg on the maintainer script environment to the version of the currently running dpkg instance (since dpkg 1.14.17).

DPKG_MAINTSCRIPT_PACKAGE Defined by dpkg on the maintainer script environment to the (non-arch-qualified) package name being handled (since dpkg 1.14.17).

DPKG_MAINTSCRIPT_PACKAGE_REFCOUNT Defined by dpkg on the maintainer script environment to the package reference count, i.e. the number of package instances with a state greater than not-installed (since dpkg 1.17.2).

DPKG_MAINTSCRIPT_ARCH Defined by dpkg on the maintainer script environment to the architecture the package got built for (since dpkg 1.15.4).

DPKG_MAINTSCRIPT_NAME Defined by dpkg on the maintainer script environment to the name of the script running, one of preinst, postinst, prerm or postrm (since dpkg 1.15.7).

DPKG_MAINTSCRIPT_DEBUG Defined by dpkg on the maintainer script environment to a value ('0' or '1') noting whether debugging has been requested (with the --debug option) for the maintainer scripts (since dpkg 1.18.4).
