I wanted to follow these instructions from another thread about reading eBooks:

If you install calibre, and you just want to read a mobi file, then you can use the ebook-reader application that installed as part of the calibre package. To do this:

  1. Right click on the mobi file and choose "Open with other application ..."
  2. expand the arrow near the bottom that says "Use a custom command"
  3. in the text box that appears, type "/usr/bin/ebook-reader"
  4. tick the box that says "Remember this application for "Mobipocket e-book" files
  5. click on the "Open" button

Unfortunately, that feature has disappeared/isn't available in my Ubuntu 11.10 standard install. Please can someone help me with a Terminal command-line for this.

  • I was under impression that you are looking for "Open with other application ..." action, which was moved to other place as explained in linked question
