dpkg-realpath(1) dpkg suite 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 /.
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.
SEE ALSO
realpath(1), readlink(1).
