DH_INSTALLDEB(1)                  Debhelper                 DH_INSTALLDEB(1)

NAME         top

       dh_installdeb - install files into the DEBIAN directory

SYNOPSIS         top

       dh_installdeb [debhelper options]

DESCRIPTION         top

       dh_installdeb is a debhelper program that is responsible for
       installing files into the DEBIAN directories in package build
       directories with the correct permissions.

FILES         top

       package.postinst
       package.preinst
       package.postrm
       package.prerm
           These maintainer scripts are installed into the DEBIAN directory.

           dh_installdeb will perform substitution of known tokens of the
           pattern #TOKEN#.  In generally, scripts will want to include the
           #DEBHELPER# to benefit from the shell scripts generated by
           debhelper commands (including those from dh_installdeb when it
           processes package.maintscript files).

           The #DEBHELPER# token should be placed on its own line as it is
           often replaced by a multi-line shell script.

       package.triggers
       package.shlibs
           These control files are installed into the DEBIAN directory.

           Note that package.shlibs is only installed in compat level 9 and
           earlier.  In compat 10, please use dh_makeshlibs(1).

       package.conffiles
           Historically, this file was needed to manually mark files files
           as conffiles.  However, it has become de facto obsolete since
           debhelper automatically computed which files should be marked as
           conffiles.

           In compatibility level up and including 11, this control file
           will be installed into the DEBIAN directory.  In compatibility
           level 12 and later, the file is silently ignored.

       package.maintscript
           Lines in this file correspond to dpkg-maintscript-helper(1)
           commands and parameters.  However, the "maint-script-parameters"
           should not be included as debhelper will add those automatically.

           Example:

               # Correct
               rm_conffile /etc/obsolete.conf 0.2~ foo
               # INCORRECT
               rm_conffile /etc/obsolete.conf 0.2~ foo -- "$@"

           In compat 10 or later, any shell metacharacters will be escaped,
           so arbitrary shell code cannot be inserted here.  For example, a
           line such as "mv_conffile /etc/oldconffile /etc/newconffile" will
           insert maintainer script snippets into all maintainer scripts
           sufficient to move that conffile.

           It was also the intention to escape shell metacharacters in
           previous compat levels.  However, it did not work properly and as
           such it was possible to embed arbitrary shell code in earlier
           compat levels.

           The dh_installdeb tool will do some basic validation of some of
           the commands listed in this file to catch common mistakes.  The
           validation is enabled as a warning since compat 10 and as a hard
           error in compat 12.

           Supports substitution variables in compat 13 and later as
           documented in debhelper(7).

OPTIONS         top

       -DTOKEN=VALUE, --define TOKEN=VALUE
           Define tokens to be replaced inside the maintainer scripts when
           it is generated.  Please note that the limitations described in
           "Limitations in token names" also applies to tokens defined on
           the command line.  Invalid token names will trigger an error.

           In the simple case, this parameter will cause #TOKEN# to be
           replaced by VALUE.  If VALUE starts with a literal @-sign, then
           VALUE is expected to point to a file containing the actual value
           to insert.

           An explicit declared token with this parameter will replace
           built-in tokens.

           Test examples to aid with the understanding:

                   cat >> debian/postinst <<EOF
                   #SIMPLE#
                   #FILEBASED#
                   EOF
                   echo -n "Complex value" > some-file
               dh_installdeb --define SIMPLE=direct --define FILEBASED=@some-file

           In this example, #SIMPLE# will expand to direct and #FILEBASED#
           will expand to Complex value.

           It is also possible to set package-specific values for a given
           token.  This is useful when dh_installdeb is acting on multiple
           packages that need different values for the same token.  This is
           done by prefixing the token name with pkg.package-name..

           This can be used as in the following example:

                   cat >> debian/foo.postinst <<EOF
                   # Script for #PACKAGE#
                   #TOKEN#
                   EOF
                   cat >> debian/bar.postinst <<EOF
                   # Script for #PACKAGE#
                   #TOKEN#
                   EOF
                   cat >> debian/baz.postinst <<EOF
                   # Script for #PACKAGE#
                   #TOKEN#
                   EOF
               dh_installdeb -pfoo -pbar -pbaz  --define TOKEN=default --define pkg.bar.TOKEN=unique-bar-value \
                 --define pkg.baz.TOKEN=unique-baz-value

           In this example, #TOKEN# will expand to default in
           debian/foo.postinst, to unique-bar-value in debian/bar.postinst
           and to unique-baz-value in debian/baz.postinst.

           Note that the #pkg.*# tokens will be visible in all scripts acted
           on.  E.g.  you can refer to #pkg.bar.TOKEN# inside
           debian/foo.postinst and it will be replaced by unique-bar-value.

SUBSTITUTION IN MAINTAINER SCRIPTS         top

       The dh_installdeb will automatically replace the following tokens
       inside a provided maintainer script (if not replaced via
       -D/--define):

       #DEBHELPER#
           This token is by default replaced with generated shell snippets
           debhelper commands.  This includes the snippets generated by
           dh_installdeb from package.maintscript file (if present).

       #DEB_HOST_NAME#, #DEB_BUILD_NAME#, #DEB_TARGET_NAME#
           These tokens are replaced with the respective variable from
           dpkg-architecture(1).  In almost all cases, you will want use the
           #DEB_HOST_NAME variant in a script to ensure you get the right
           value when cross-building.

           On a best effort, tokens of this pattern that do not match a
           variable in dpkg-architecture(1) will be left as-is.

       #ENV.NAME#
           These tokens of this form will be replaced with value of the
           corresponding environment variable.  If the environment variable
           is unset, the token is replaced with the empty string.

           Note that there are limits on which names can be used (see
           "Limitations in token names").

       #PACKAGE#
           This token is by default replaced by the package name, which will
           contain the concrete script.

   Limitations in token names
       All tokens intended to be substituted must match the regex:
       #[A-Za-z0-9_.+]+#

       Tokens that do not match that regex will be silently ignored if found
       in the script template.  Invalid token names passed to -D or --define
       will cause dh_installdeb to reject the command with an error in most
       cases.
