Changing capitalization of filenames in Git

Question

I am trying to rename a file to have different capitalization from what it had before   git mv src collision b2AABB js src collision B2AABB js fatal  destination exists  source src collision b2AABB js  destination src collision B2AABB js   As you can see  Git throws a fit over this  I tried renaming using just the plain old mv command as well  but Git doesn t pick up the rename  as a rename or as a new untracked file    How can I change a file to have a different capitalization of the same name  I am on Mac nbsp OS nbsp X nbsp v10 7 3  Lion  with Git 1 7 9 1 using Z shell  zsh  4 3 15

Set ignorecase to false in git config  As the original post is about  Changing capitalization of filenames in Git    If you are trying to change capitalisation of a filename in your project  you do not need to force rename it from Git  IMO  I would rather change the capitalisation from my IDE editor and make sure that I configure Git properly to pick up the renaming   By default  a Git template is set to ignore case  Git case insensitive   To verify you have the default template  use --get to retrieve the value for a specified key  Use --local and --global to indicate to Git whether to pick up a configuration key-value from your local Git repository configuration or global one  As an example  if you want to lookup your global key core ignorecase   git config --global --get core ignorecase   If this returns true  make sure to set it as   git config --global core ignorecase false    Make sure you have proper permissions to change global   And there you have it  now your Git installation would not ignore capitalisations and treat them as changes   As a suggestion  if you are working on multi-language projects and you feel not all projects should be treated as case-sensitive by Git  just update the local core ignorecase file

File names under OS X are not case sensitive  by default   This is more of an OS problem than a Git problem  If you remove and readd the file  you should get what you want  or rename it to something else and then rename it back

Starting Git 2 0 1  June 25th  2014   a git mv will just work on a case insensitive OS   See commit baa37bf by David Turner  dturner-tw    mv  allow renaming to fix case on case insensitive filesystems   git mv hello txt Hello txt  on a case insensitive filesystem always triggers  destination already exists  error  because these two names refer to the same path from the filesystem s point of view and requires the user to give  --force  when correcting the case of the path recorded in the index and in the next commit      Detect this case and allow it without requiring  --force     git mv hello txt Hello txt just works  no --force required anymore      The other alternative is   git config --global core ignorecase false   And rename the file directly  git add and commit

Sometimes you want to change the capitalization of a lot of file names on a case insensitive filesystem  e g  on OS nbsp X or Windows   Doing git mv commands will tire quickly  To make things a bit easier this is what I do    Move all files outside of the directory to  let   s  say the desktop  Do a git add   -A to remove all files  Rename all files on the desktop to the proper capitalization  Move all the files back to the original directory  Do a git add    Git should see that the files are renamed    Now you can make a commit saying you have changed the file name capitalization
