When I execute following command:

cd ./avast4workstation_1.3.0-2_i386.deb


cd '/home/ravi/avast4workstation_1.3.0-2_i386.deb'

I get this error message:

bash: cd: /home/ravi/Downloads/20120409121148448001.pdf: Not a directory

How do I solve this problem?

As ephsmith said, these are not directories. To open them, use gnome-open FILE (replacing FILE with the file you want to open). – MiJyn Jul 19 '12 at 2:30
If trying to install try sudo dpkg -i avast4workstation_1.3.0-2_i386.deb go to dash and type avast click the link saying "Click here to obtain license key" and follow the rest of the on screen prompts – damien Jul 19 '12 at 4:54
@ephsmith Put that as the answer. – Uri Herrera Jul 19 '12 at 6:41
@lkjoel You can post that as the answer too, both are correct. – Uri Herrera Jul 19 '12 at 6:42
If no-one posts it as an answer I will and I will steal all your reputation :+ – Rinzwind Jul 19 '12 at 6:47
  • If you want to open any file from terminal, you should issue command like

    gnome-open ~/Downloads/photo.rar

Here, photos.rar is file I want to open in the directory ~/Downloads/.

BTW, ~is used for user's home directory. ~/Downloads/photo.rar will be interpreted like /home/USER_NAME/Downloads/photo.rar.

  • if you are trying to install .deb file, you should issue

    sudo dpkg -i /home/ravi/avast4workstation_1.3.0-2_i386.deb

also, this can be done like this,

cd /home/ravi/
sudo dpkg -i avast4workstation_1.3.0-2_i386.deb

remember you can use cd ~ instead cd /home/ravi/.

  • if you want to execute a file which is in current directory, then you should use


Here can be any executable file.

Note: if path contains special characters like, spaces you should put it between single quote like '/home/ravi/avast4workstation 1.3.0-2 i386.deb' or you should escape special characters like /home/ravi/avast4workstation\ 1.3.0-2\ i386.deb

Hope I haven't confused you.

cd is a shell command to change to a directory, so it would not work to try to change directories into a file. If you tried to open these the same way you open a file in a file manager, you would have to use this:

gnome-open FILE

What that does is that it opens FILE using the default program associated with the type of that file.
