shtool-subst - GNU shtool sed(1) substitution operations

       This command applies one or more sed(1) substitution operations to stdin or any number of files.

        #   shell script
        shtool subst -i -e 's;(c) \([0-9]*\)-2000;(c) \1-2001;' *.[ch]

        #    RPM spec-file
        %install
            shtool subst -v -n \
                -e 's;^\(prefix=\).*;\1 $RPM_BUILD_ROOT%{_prefix};g' \
                -e 's;^\(sysconfdir=\).*;\1 $RPM_BUILD_ROOT%{_prefix}/etc;g' \
                `find . -name Makefile -print`
            make install

       The GNUshtoolsubst command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 2001
       for GNUshtool.  It was prompted by the need to have a uniform and convenient patching frontend to sed(1)
       operations in the OpenPKG package specifications.
