How to show a script without comments?

[Ralf Mardorf]

Hi,

how can I display a shell script without comments and empty lines, but
also without cutting commands?

This is an example text file:

  [weremouse at moonstudio tmp]$ cat test.txt 
  ## test file.
  test # test
  test 2
  echo "Hello #"
  echo "Hello #" # Oops

A simple egrep line, doesn't remove all comments:

  [weremouse at moonstudio tmp]$ egrep -v "^#|^$" test.txt 
  test # test
  test 2
  echo "Hello #"
  echo "Hello #" # Oops

A simple sed line, does remove all comments, but cuts commands:

  [weremouse at moonstudio tmp]$ sed "s/#.*$//g" test.txt | grep -v ^$
  test 
  test 2
  echo "Hello 
  echo "Hello

Regards,
Ralf
