dh-exec

DH-EXEC(1)							      dh-exec								DH-EXEC(1)

NAME

       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.
