If you want your script to behave like the ksh itself (ignore the part of a line after a "#" but use the part before it) you could do the following (replace "<spc>" with a literal space, "<tab>" with a tab char):

Code:
script

sed 's/#.*$/;s/^[<spc><tab>]*//;s/[<spc><tab>]*$//;/^$/d' file

content of file
# this is a line with comments
   # this too, but starting with blanks
command 1        # this line contains an inline comment

command 2 "#"   # this too, but my script would be confused

result
command 1
command 2 "

Alas, the script fails on the second line, but save for such delicacies it works.

LEARN ABOUT DEBIAN

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.
