Git diff --name-only -z pathname quoting documentation core.quotePath C-style quoted filenames

💡 Result:

In Git, commands that output pathnames—such as git diff --name-only—default to quoting "unusual" characters in filenames [1][2]. This behavior is controlled by the configuration variable core.quotePath [2][3]. When core.quotePath is enabled (the default), Git inspects pathnames for characters deemed "unusual," which include control characters (such as TAB, LF, and backslash) and non-ASCII bytes (values greater than 0x80) [2][3][4]. If any such character is detected, the entire pathname is enclosed in double quotes, and the special characters are escaped using C-style backslash notation (e.g., \t, \n, \, or octal sequences like \302\265) [2][3]. Notably, a simple space is not considered an "unusual" character and does not trigger this quoting behavior [2][4]. If core.quotePath is set to false, Git stops quoting non-ASCII bytes (values > 0x80) and outputs them verbatim [2][3]. However, double quotes, backslashes, and control characters will still be escaped regardless of this setting [2][3]. To bypass this quoting mechanism entirely and receive filenames verbatim regardless of their content, you can use the -z option [1][5][2]. When -z is used with commands like git diff --name-only, pathnames are output exactly as they are, and each entry is terminated by a NUL byte rather than a newline [1][5][2]. Configuration: You can disable the automatic quoting of non-ASCII characters by running: git config --global core.quotePath false Top results: [1] https://git-scm.com/docs/git-diff [2] https://git-scm.com/docs/git-config/2.20.0 [3] https://linux.die.net/man/1/git-config [4] https://public-inbox.org/git/201001011844.23571.agruen@suse.de/T/

Decode Git pathnames before shell escaping in both utilities.

git diff --name-only and git show --name-only can emit C-quoted pathnames. escapeshellarg() then passes the encoded text to PHPCS, so PHPCS may skip the changed file. Use -z, split $fileList on "\0", and escape each raw pathname in both utilities.
