By default, Git treats file names in a case-sensitive manner. This means that
File.txt would be considered two separate files. However, depending on your operating system’s file system, this might not always be the case. Some file systems, like NTFS on Windows, are case-insensitive by default, which means
File.txt would be considered the same file.
So, generally speaking, Git will show you the differences between these two files if you were to use
git diff file.txt File.txt in a case-sensitive file system like ext4 in Linux.
However, the core.ignorecase configuration variable in Git tells the system whether to be case sensitive or insensitive. If you want to ensure case sensitivity in Git irrespective of the underlying file system, you need to make sure that
core.ignorecase is set to
Here’s how you can check the current setting and change it if necessary:
First, you can check the current value of the
core.ignorecase setting with the following command:
git config --get core.ignorecase
If the output is
true, it means Git is currently set to ignore case. To switch to case-sensitive behavior, you can set
false with the following command:
git config core.ignorecase false
This will ensure that Git handles file names in a case-sensitive manner.
Remember, it’s typically best to leave this setting at its default value unless you have a specific reason to change it. This is because changing it might lead to unexpected results when working with repositories on different file systems.
git diff is used to see the differences between two sets of code. If you want to see the differences between two specific files with different casing, you would use:
git diff -- file.txt File.txt
-- before the filenames, which is used to specify that
File.txt are paths, not revision parameters or paths to other Git objects.
If you have made changes to the files and you want to see the differences, you would add those files to the staging area using
git add and then use
git diff --staged to view the differences.
These commands provide a comprehensive way to handle and view case-sensitive differences in Git.
