    thank u for the demonstration. I got ask u a question i.e i had a file 200M and created a hardlink for this file the actual disk space will 400M for both files or 200M.since u run ls -li will show both file point to same inode and they had the same size

    • @Faisal,
      The process of creating a hard link does NOT duplicate the file. So if you have a 200 MB file and create a hard link to it, the hard link itself will not occupy another extra 200 MB. One way you can check this is by doing
      du -sch /full/path/to/directory/*
      where /full/path/to/directory/ is the directory where you have the 200 MB file. Do that and then delete the hard link, then try again. You will not see a difference in the disk usage.

    In the ‘hard & soft link’, maybe the phrase ‘On the other hand, creating a hard link results in an extra disk usage of 5 bytes.’ should be ‘On the other hand, creating a soft link results in an extra disk usage of 5 bytes.’, isn’t it?

    • @Eduardo,
      Good catch! Yes, that is a typo. Thanks for bringing that up to our attention. I’ll ask Ravi to correct it.

      • Neeraj Rawat says:

        It should be corrected by now, more than a year now. Still, points to hard link. If you wish can also update that why hard links can’t be created for directories.

    While ‘&> ‘ works in récent Bash,
    ‘2>&1 ‘ Will redirect stdout “to where stderr is” on close to every shell around.

    Small mistake, in tar compression flags you have commit (should be uppercase J instead lowercase j for xz compression ).

    PS.
    Thanks for that two articles, for me is some kind of reapet …

    This bit “2>>” should not be “Appends standard error to a file”?
