Re: [PATCH 1/2] rm: better error message on failure for multiple files

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Please ignore this, manipulation error while in the git send-email command line.

Le 2013-06-10 14:51, Mathieu Lienard--Mayor a écrit :
When 'git rm' fails, it now displays a single message
with the list of files involved, instead of displaying
a list of messages with one file each.

As an example, the old message:
	error: 'foo.txt' has changes staged in the index
	(use --cached to keep the file, or -f to force removal)
	error: 'bar.txt' has changes staged in the index
	(use --cached to keep the file, or -f to force removal)

would now be displayed as:
	error: the following files have changes staged in the index:
		foo.txt
		bar.txt
	(use --cached to keep the file, or -f to force removal)
