DH-EXEC-INSTALL(1)

NAME
dh-exec-install - Install (and possibly rename) files.

SYNOPSIS
#! /usr/bin/dh-exec
debian/default.conf => /etc/my-package/start.conf
=> /usr/bin/runme
usr/bin/*
[linux-any kfreebsd-any] some-arch-specific-file /usr/lib/foo/

DESCRIPTION
Being a sub-command of dh-exec(1), this program must not be ran directly, but through dh-exec, which automatically runs all available sub-commands if run bare; or explicitly with dh-exec --with=install. It is meant to be used for the dh_install(1) family of files, and those alone. If it finds that its input is not such a file, it will do nothing, but echo back the contents. For a full list of recognised files, see the FILE TYPES section of this manual. The purpose of the program is to extend dh_install(1)'s functionality, by allowing to specify a destination filename, and a way to move (instead of copy) a file to a single package. The first can be accomplished by a special syntax: the " => " mark between a source and a destination means that the source file should be installed with the specified destination name. For obvious reasons, the source must not be a wildcard, and the destination in this case must be a file, and not a directory. The second extension follows a simpler syntax: any filename prefixed with "=>" will be moved instead of copied to the package. This allows one to move a file out of a directory to a package, and install the rest of the files in the same dir into another package. See the FILTERING section of dh-exec(1) for more information about how lines are filtered. Any non-comment lines without a filter will be left alone.

RESTRICTIONS
Due to the way executable scripts are called from dh(1), there is no way to know what options were used for the original dh_install(1). This means, that the --sourcedir option of dh_install(1) will not work correctly when dh-exec-install is in use.

FILE TYPES
The program supports dh_install(1) and dh_installmanpages(1) files only.

IMPLEMENTATION
Internally, the renaming happens by creating a temporary directory under debian/tmp/, and copying (or moving, if the source was under debian/tmp/ to begin with) the file there, with the new name. This is done this way to allow dh_install(1) to do the real copying, and allow its options to continue working, even when renaming is involved. The temporary directory is put under debian/tmp so that it will be cleaned by dh_prep(1) when the clean target gets to run. Thus, no extra code is needed anywhere to clean up the renamed files.

ENVIRONMENT

DH_EXEC_SCRIPTDIR
    Indicates which directory the command-specific scripts should be sought for. If not specified, scripts will be searched for in /usr/share/dh-exec/.

FILES

$DH_EXEC_SCRIPTDIR/dh-exec-install-*
    The various scripts for the higher-level program.

VERSIONS
The sub-command was introduced in dh-exec version 0.1. Support for dh_installmanpages(1) files were added in version 0.13.
