Using git difftool for files comparsion in Debian Linux v. 10 (buster)

Question

In Debian Linux v. 9 I use following command to do files comparison and this command is working OK:

git difftool /file/a /file/b

In Debian Linux v. 10 I use this command in the same way and have following error:

fatal: not a git repository (or any of the parent directories): .git

Help me, please, resolve it.

PS: I don't use any git-repositories in the work, just only difftool from git.

Is the git version the same on both devices? Is there a `.git` directory in your Debian 9 device? — dan1st, Jul 01 '21 at 20:27
@dan1st, no in first example git's version: 2.11.0, in second: 2.20.1; no, no .git directory in both examples... — mshta, Jul 01 '21 at 20:42

You need git version 2.22.0 or higher. In 2.22.0 git difftool can run outside a repository. See https://github.com/git/git/blob/master/Documentation/RelNotes/2.22.0.txt

Thanks you! So, in Git v. 2.20.0 I have no parameters to run following command: `git difftool`, outside Git repository? – mshta Jul 05 '21 at 10:33
@mshta Alas, no. – phd Jul 05 '21 at 11:55
