Sometimes working with other people you wish you didn’t have some of the files
in the repository because they are getting in the way of your settings. .ruby-version
for instance.
You check out the repository and what the…
$ git clone ...
...
rbenv: version '2.1.5' is not installed
Okay you delete the pesky .ruby-version but now it is there for every commit:
$ rm .ruby-version
$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
Changes not staged for commit:
(use "git add/rm <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)
deleted: .ruby-version
It’s impossible to ignore it by adding it to .gitignore but fortunately in git
there is an option for everything.
$ git update-index --assume-unchanged .ruby-version
$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean
Done! Phew, at least this wasn’t too much typing, was it? Another option is to truncate the file:
$ cat >> ~/.gitignore
.ruby-version
^C
rbenv: version '2.1.5' is not installed
$ cat > .ruby-version
^C
$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean
And as always be careful with git, don’t mess things up.
