fatal: No HEAD commit to compare with (yet)

Question

I am newbie with git. It tried this tutorial, but after the command, i get this error:

[root@WL-0022150E7BD4 alma]$ git diff --cached
fatal: No HEAD commit to compare with (yet)

I created two file in the current directory. I dont understand, it is the first step in the tutorial.

Answer 1

It's not the first step in the tutorial: you should have done git init, git add . (with at least some files in the working directory), git commit and another git add before you do a git diff --cached.

Provided that there wasn't an error in the commit step, git diff --cached should not give you this error.
