Sequence of commands that i used to restore .

git status
On branch master
Your branch is ahead of 'origin/master' by 1 commit.
  (use "git push" to publish your local commits)
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

I am unable to restore file on Ubuntu 14.10 ,git version 2.1.0 . Is there a way so that i can restore file?

Detective work

Based on your description of the problem, before running into trouble, your repo's history must have consisted of two commits:

9b72b0c first commit
fc9895a IF ELSE (HEAD, master)

Evidence

• Information about your second commit is in the output of

   git commit -m 'IF ELSE' 

• The output of

   git reset --hard HEAD^1 

  (this commands resets the current branch to the parent of the current commit) indicates that the parent of fc9895a has SHA 9b72b0c and message first commit .

Reset your branch to the desired state

Since you haven't made any local changes after running git rm * , all you have to do is go back to the state your repository was in right after you made the IF ELSE commit.

Fortunately, you still have a record of the short SHA of that commit: fc9895a . Therefore,

git reset --hard fc9895a

is the command that will get you out of trouble.

Explanation

git-reset is used to reset the current branch ( master , here) to the specified state ( fc9895a , here).

And the git-reset man page describes the --hard flag thus:

--hard

Resets the index and working tree. Any changes to tracked files in the working tree since <commit> are discarded.

(Use with caution!)

Here is a good introduction to how git-reset works.
