Dpkg::Path(3) libdpkg-perl Dpkg::Path(3)NAMEDpkg::Path - some common path handling functions
It provides some functions to handle various path.
This function will scan upwards the hierarchy of directory to
find out the directory which contains the "DEBIAN" sub-
directory and it will return its path. This directory is the
root directory of a package being built.
If no DEBIAN subdirectory is found, it will return undef.
Returns the filename relative to get_pkg_root_dir($file).
This function tries to guess the root directory of the package
build tree. It will first use get_pkg_root_dir(), but it will
fallback to a more imprecise check: namely it will use the
parent directory that is a sub-directory of the debian
It can still return undef if a file outside of the debian sub-
directory is provided.
check_files_are_the_same($file1, $file2, $resolve_symlink)
This function verifies that both files are the same by checking
that the device numbers and the inode numbers returned by
stat()/lstat() are the same. If $resolve_symlink is true then
stat() is used, otherwise lstat() is used.
This function returns a cleaned path. It simplifies double //,
and remove /./ and /../ intelligently. For /../ it simplifies
the path only if the previous element is not a symlink. Thus it
should only be used on real filenames.
$newpath = resolve_symlink($symlink)
Return the filename of the file pointed by the symlink. The new
name is canonicalized by canonpath().
my $cmdpath = find_command($command)
Return the path of the command if available on an absolute or
relative path or on the $PATH, undef otherwise.
my $control_file = get_control_path($pkg, $filetype)
Return the path of the control file of type $filetype for the
my @control_files = get_control_path($pkg)
Return the path of all available control files for the given
my $file = find_build_file($basename)
Selects the right variant of the given file: the arch-specific
variant ("$basename.$arch") has priority over the OS-specific
variant ("$basename.$os") which has priority over the default
variant ("$basename"). If none of the files exists, then it
my @files = find_build_file($basename)
Return the available variants of the given file. Returns an
empty list if none of the files exists.
