But the question is not only of file managers, that was only an example. Another example might be looking for a package to install:
Code:
$ aptitude search qt | grep ruby
p   libqt0-ruby1.8                  - Qt3 bindings for Ruby
p   libqt4-ruby                     - Qt 4 Ruby bindings
p   libqt4-ruby1.8                  - Qt 4 bindings for Ruby
p   libqt4-ruby1.8-dev              - Qt 4 bindings for Ruby - development files
p   libqt4-ruby1.8-examples         - Qt 4 bindings for Ruby - example files
p A libqtruby4shared2               - internal library for Qt 4 Ruby bindings
$

Now I know that I want to install the second and fifth packages. Must I manually type in "sudo apt-get install libqt4-ruby libqt4-ruby1.8-examples"? Why can't there be a simple "sudo apt-get install ^2 ^5"? Should I file a feature request at bash? Is this not something that would be useful to many people?
The problem is that the shell isn't even looking at the output of your first command. The shell's fd for stdout is simply being copied into the subprocess that is running find/aptitude/etc. and that is outputing directly to your console.

       -v, --verbose
	   Display some processing information.

       -t, --trace
	   Enable the output of the essential shell commands which are executed.

       -n, --nop
	   No operation mode. Actual execution of the essential shell commands which would be executed is suppressed.

       -w, --warning
	   Show warning on substitution operation resulting in no content change on every file. The default is to show a warning on substitution
	   operations resulted in no content change on all files.

       -q, --quiet

	%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

HISTORY

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

SEE ALSO

       shtool(1), sed(1).
