SYNOPSIS
#! /usr/bin/dh-execsrc/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.
Introduced in version 0.1.
- 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).
Introduced in version 0.1.
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/.
