    Dear Gabriel Canepa
    Thank you for excelent material about LFCS exam. Just I would like to know. In your article you wrote that the compressed folder cannot be updated. I would like to know how about tar -rvf ?

    • @Agil,
      Thank you for your question. Note that you can use tar -rvf to append files to an existing TAR file (.tar) but NOT to a compressed file (.tar.gz). If you try to add a file named foo to mycompressedfile.tar.gz as follows:
      tar -rvf mycompressedfile.tar.gz foo
      You’ll get the following error:
      tar: Cannot update compressed archives
      tar: Error is not recoverable: exiting now
      Hope it helps!

    Hi Gabriel, thanks for this great course. I want to take the LFCS exam next Friday, Could you help me with some advices?. LFCS is more about your practice skills but I need to know by heart all commands?.

      I am glad that you have found this series useful.
      The Linux Foundation just published a QA page about the certification programs http://t.co/1Oa9MwYpaQ. I would advice you to check it out.
      In addition, you should practice amd polish your command line skills until you feel comfortable. You can use different tools during the exam as long as they are in the Allowed list in the QA page mentioned above. So you can choose to perform a certain task using the resources you feel more comfortable with.
      Finally, you may want to check The Linux Command Line from linuxcommand.org.
      Hope it helps and good luck in the exam!
