Help looping through files, please...
Okay...

I've solved one problem.

Here's the next.

I'm writing a script file that needs to go through a directory and list all files in that directory.

I'm using TCL/TK.

I figured out how to go through the directory and how to loop through it, but I ran into a little problem.

Example:

Say you have a top most directory called:

dir_A

Within dir_A there are some files:

dir_A
- file1
- file2

To loop through in TCL/TK i'd do this:

set files [glob -nocomplain *] #basically an ls unix call

if { $files != "" } {
foreach filename $files {
puts $filename #print to screen
}
}

That works if the directory structure has only one directory with files in it.

BUT what if the structure looks like this:

dir_A
- file1
- file2
- dir_B
- file1
- file2

The above code snippet would only print to screen:

% dir_A
% file1
% file2
% dir_B

I would like to be able to print out what is also in dir_B so that the output would be:

% dir_A
% file1
% file2
% dir_B
% file1
% file2

Any ideas?

dh_installdeb

DH_INSTALLDEB(1)						     Debhelper							  DH_INSTALLDEB(1)

NAME

       dh_installdeb - install files into the DEBIAN directory

SYNOPSIS

       dh_installdeb [debhelperoptions]

DESCRIPTION

       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

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

	   Inside the scripts, the token #DEBHELPER# is replaced with shell script snippets generated by other debhelper commands.

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

       package.conffiles
	   This control file will be installed into the DEBIAN directory.

	   In v3 compatibility mode and higher, all files in the etc/ directory in a package will automatically be flagged as conffiles by this
	   program, so there is no need to list them manually here.

       package.maintscript
	   Lines in this file correspond to dpkg-maintscript-helper(1) commands and parameters.  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.

	   A versioned Pre-Dependency on dpkg is needed to use dpkg-maintscript-helper(1). An appropriate Pre-Dependency is set in
	   ${misc:Pre-Depends} ; you should make sure to put that token into an appropriate place in your debian/control file.
