dpkg-realpath(1)

NAME
dpkg-realpath - print the resolved pathname with DPKG_ROOT support

SYNOPSIS
dpkg-realpath [option...] pathname

DESCRIPTION
dpkg-realpath is a tool (since dpkg 1.20.1) to resolve a pathname, that takes the dpkg(1) root directory into account, either implicitly from the DPKG_ROOT environment variable or from the command-line --root or --instdir options, and returns an absolute pathname relative to the root directory. The root directory must not be prefixed to the pathname to be resolved.

This is intended to be used by other dpkg helpers, or by maintainer scripts instead of using realpath(1) or readlink(1) to canonicalize pathnames, as these latter commands do not support canonicalization relative to a different root than /.

This program was introduced in dpkg 1.20.1.

OPTIONS

-z, --zero
    Use a NUL byte to end output lines instead of a new line character (since dpkg 1.20.6).

--instdir directory
--root directory
    Set the root directory to directory, which is the base directory that pathnames get canonicalized against. Defaults to «/» if DPKG_ROOT has not been set.

-?, --help
    Show the usage message and exit.

--version
    Show the version and exit.

ENVIRONMENT

DPKG_ROOT
    If set and the --instdir or --root options have not been specified, it will be used as the filesystem root directory.

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

DPKG_NLS
    If set, it will be used to decide whether to activate Native Language Support, also known as internationalization (or i18n) support (since dpkg 1.22.7). The accepted values are: 0 and 1 (default).
