Given two directory trees, how can I find out which files differ?
If I want find the differences between two directory trees, I usually just execute:
diff -r dir1/ dir2/
This outputs exactly what the differences are between corresponding files. I'm interested in just getting a list of corresponding files whose content differs. I assumed that this would simply be a matter of passing a command line option to diff , but I couldn't find anything on the man page.
Any suggestions?
You said Linux, so you luck out (at least it should be available, not sure when it was added):
diff --brief -r dir1/ dir2/
Should do what you need.
If you also want to see differences for files that may not exist in either directory:
diff --brief -Nr dir1/ dir2/
The command I use is:
diff -qr dir1/ dir2/
It is exactly the same as Mark's :) But his answer bothered me as it uses different types of flags, and it made me look twice. Using Mark's more verbose flags it would be:
diff --brief --recursive dir1/ dir2/
I apologise for posting when the other answer is perfectly acceptable. Could not stop myself... working on being less pedantic.
我喜欢使用git diff --no-index dir1/ dir2/ ，因为它可以显示颜色的差异（如果您在git配置中设置了该选项），并且它显示使用长分页输出时的所有差异“减”。
