      Add to .cvsignore




Locations of visitors to this page

This is a very simple perl script that adds entries to the .cvsignore file. I find it useful, as before adding a project to CVS using Eclipse, I walk through my directory structure and on the fly add things to .cvsignore.

  1. #!/usr/bin/perl -w
  2. ############################################
  3. #
  4. # Add files to the .cvsignore file.
  5. #
  6. ############################################
  7. # The file .cvsignore  is created if not yet
  8. # there. The entries are sorted. If an entry
  9. # is already there, it is not added again.
  10. #
  11. # You can use stdin like
  12. #
  13. # ls -1 *.class | cvsignore
  14. #
  15. # or you can pass command line parameters
  16. #
  17. # cvsignore *.class
  18. #
  19. # If the parameter is "-d", the entry is de-
  20. # leted;
  21. #
  22. # cvsignore -d *.class
  23. #
  24. # The  -d  can be passed at any place in the
  25. # command line:
  26. #
  27. # cvsignore *.java -d *.class
  28. #
  29. # Once you passed -d,  the rest of  the line
  30. # will be deleted until the next -d.
  31. #
  32. # -d cannot be used together with stdin.
