dh-exec - Debhelper executable file helpers SYNOPSIS
#! /usr/bin/dh-exec src/libfoo-*.so.* debian/foo-plugins/usr/lib/foo/${DEB_HOST_MULTIARCH}/ etc/example.conf => debian/foo/etc/foo/foo.conf DESCRIPTION
dh-exec is a simple program, meant to be used as the interpreter for executable debhelper config files. It is a wrapper around the various other sub-commands (see below), and will pipe the input file through all of them in turn, using an ordering that makes most sense in the vast majority of cases. The order as of now is dh-exec-subst gets run first, followed by dh-exec-install, so that variable expansion happens before files need to be copied. ARCHITECTURE
dh-exec is built up from three layers: there is the dh-exec utility, its single entry point, the only thing one will need to call. Below that, there are the various sub-commands, such as dh-exec-subst, dh-exec-installs and dh-exec-illiterate, which are thin wrappers around the various dh-exec scripts, that make sure they only run those that need to be run. And the lowest layer are the various scripts that do the actual work. One can control which sub-commands to run, or if even more granularity is desired, one can limit which scripts shall be run, too. See below for the options! OPTIONS
--with=command[,command ...] Replace the list of sub-commands to run the input through with a custom list (where entries are separated by whitespace or commas). This option will always replace the existing list with whatever is specified. This can be used to explicitly set which sub-commands to use. The list must not include the dh-exec- prefix. Defaults to subst,install. --without=command[,command ...] Inversely to the option above, this lists all the sub-commands which should not be used. The list must not include the dh-exec- prefix. --with-scripts=script[,script ...] Replace the list of scripts to run the input through with a custom list (where entries are separated by whitespace or commas). This option will always replace the existing list with whatever is specified. This can be used to explicitly specify which scripts to use, limiting even beyond what the --with option is capable of. The list must not include the dh-exec- prefix. By default it is empty, meaning there is no filtering done, and whatever scripts the sub-commands find, will be run. --no-act Do not really do anything, but print the pipeline that would have been run instead. --list List the available sub-commands and scripts, grouped by sub-command. --help, --version Display a short help or the package version, respectively. SUB-COMMANDS dh-exec-subst Substitutes various variables (either from the environment, or from dpkg-architecture(1)). dh-exec-install An extension to dh_install(1), that supports renaming files during the copy process, using a special syntax. ENVIRONMENT
DH_EXEC_LIBDIR The directory in which the wrapped sub-commands reside. Defaults to /usr/lib/dh-exec/. DH_EXEC_SCRIPTDIR The directory in which the scripts that do the heavy work live. Defaults to /usr/share/dh-exec/. FILES
$DH_EXEC_LIBDIR/dh-exec-* The various sub-commands. $DH_EXEC_SCRIPTDIR/dh-exec-* The various scripts ran by the sub-commands. SEE ALSO

DH_INSTALL(1) Debhelper DH_INSTALL(1) NAME
dh_install - install files into package build directories SYNOPSIS
dh_install [-Xitem] [--autodest] [--sourcedir=dir] [debhelperoptions] [file|dir...destdir] DESCRIPTION
dh_install is a debhelper program that handles installing files into package build directories. There are many dh_install* commands that handle installing specific types of files such as documentation, examples, man pages, and so on, and they should be used when possible as they often have extra intelligence for those particular tasks. dh_install, then, is useful for installing everything else, for which no particular intelligence is needed. It is a replacement for the old dh_movefiles command. This program may be used in one of two ways. If you just have a file or two that the upstream Makefile does not install for you, you can run dh_install on them to move them into place. On the other hand, maybe you have a large package that builds multiple binary packages. You can use the upstream Makefile to install it all into debian/tmp, and then use dh_install to copy directories and files from there into the proper package build directories. From debhelper compatibility level 7 on, dh_install will fall back to looking in debian/tmp for files, if it does not find them in the current directory (or wherever you've told it to look using --sourcedir). FILES
debian/package.install List the files to install into each package and the directory they should be installed to. The format is a set of lines, where each line lists a file or files to install, and at the end of the line tells the directory it should be installed in. The name of the files (or directories) to install should be given relative to the current directory, while the installation directory is given relative to the package build directory. You may use wildcards in the names of the files to install. Note that if you list exactly one filename or wildcard-pattern on a line by itself, with no explicit destination, then dh_install will automatically guess the destination to use, the same as if the --autodest option were used. debian/not-installed Used with the deprecated --list-missing and --fail-missing options. Please refer to dh_missing(1) for the documentation of this file. OPTIONS
--list-missing Deprecated: Please use dh_missing --list-missing instead. If you use this option, dh_install will call dh_missing with that option after it has processed all the files. Please see dh_missing(1) for the documentation of this option. This option is removed in compat 12. --fail-missing Deprecated: Please use dh_missing --fail-missing instead. If you use this option, dh_install will call dh_missing with that option after it has processed all the files. Please see dh_missing(1) for the documentation of this option. This option is removed in compat 12. --sourcedir=dir Look in the specified directory for files to be installed. Note that this is not the same as the --sourcedirectory option used by the dh_auto_* commands. You rarely need to use this option, since dh_install automatically looks for files in debian/tmp in debhelper compatibility level 7 and above. --autodest Guess as the destination directory to install things to. If this is specified, you should not list destination directories in debian/package.install files or on the command line. Instead, dh_install will guess as follows: Strip off debian/tmp (or the sourcedir if one is given) from the front of the filename, if it is present, and install into the dirname of the filename. So if the filename is debian/tmp/usr/bin, then that directory will be copied to debian/package/usr/. If the filename is debian/tmp/etc/passwd, it will be copied to debian/package/etc/. file|dir ... destdir Lists files (or directories) to install and where to install them to. The files will be installed into the first package dh_install acts on. LIMITATIONS
dh_install cannot rename files or directories, it can only install them with the names they already have into wherever you want in the package build tree. However, renaming can be achieved by using dh-exec with compatibility level 9 or later. An example debian/package.install file using dh- exec could look like: #!/usr/bin/dh-exec debian/default.conf => /etc/my-package/start.conf Please remember the following three things: o The package must be using compatibility level 9 or later (see debhelper(7)) o The package will need a build-dependency on dh-exec. o The install file must be marked as executable.
