We have common mistakes list http://www.webminal.org/common_mistakes/ http://www.webminal.org/common_mistakes/ but didn't figure-out something like which is the least-used valid command. Good idea, we will dig deeper into their bash_history :)

I think ".." was "cd .." in dos
- giis 11y ago
  hmm..that's interesting,I never knew that. thanks.

  Just checked the cmd prompt on Windows 7 and it isn't like that now at any rate. However cd.. (no space) works.

  .. is "cd .." in fish shell
  - nilved 11y ago
    zsh and (possibly) Bash can be configured that way as well.
    - giis 11y ago
      configured using bash alias ?
      - nilved 11y ago
        No, the `auto_cd` option, just like in zsh.
        Retra 11y ago
        In zsh you can just use " alias ..='cd ..'

  I have ".." as an alias for "cd .." I also have "la" as an alias for "ls -a", and "lsa" as an alias for "ls -lah --color=auto"

Some linux distros (used to?) alias ls -a to la, which would explain why you're seeing it so often.
- giis 11y ago
  You are right, quick google search says 'Ubuntu 12.14' has ls,l and la. Will update our page to reflect this.

    Just checked and it's still there at least in Ubuntu 14.04 LTS.

  And some would also alias "ls -la" to ll. Just never the computer I'm using at the time.
  - giis 11y ago
    yes, from time to time, I used to perform 'll' too. I guess some distro comes with that alias by default.

You should also analyse commands that were run without 'sudo'. For me, using 'apt-get install' without sudo has been the most frequent mistake I have made. Luckily, 'sudo !!' saves me every time.

  thanks for the nice suggestion. Will analyse this type of common mistake too.
