DH-EXEC-SUBST(1) dh-exec DH-EXEC-SUBST(1)
NAME
dh-exec-subst - Debhelper executable file substition scripts
SYNOPSIS
#! /usr/bin/dh-exec
src/libfoo-*.so.* debian/foo-plugins/usr/lib/foo/${DEB_HOST_MULTIARCH}/
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=subst.
It is a wrapper around the various other substitution helpers, and will pipe the input file through all the available substitution helpers.
It is up to these scripts to do the actual work.
When a helper fails to expand a variable within its input, it will leave it as-is, so that later in the pipeline it can perhaps be expanded
by another program.
SCRIPTS
dh-exec-subst-env
Substitutes any of the available, exported environment variables into its input. It does not do any kind of filtering: whatever is
available in the environment, will be available for substitution, however unsafe that may be.
dh-exec-subst-multiarch
Attempts to expand any of the variables known to dpkg-architecture(1), mostly useful for multi-arch support.
The command will query dpkg-architecture(1) directly, and does not rely on environment variables set (as the called program will
prefer already set environment variables anyway).
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-subst-*
The various scripts for the higher-level program.
