我想要比较两个目录。我尝试了diff，但它包含了文件内部的更改。我想要的只是这样的
file a is just in /A
file b is missing in /A
file c changed
directory d is missing in /A
directory e is just in /A
我认为这在进行完整文件修补时很常见，但我不知道一个好的解决方案。
您正在寻找
diff -rq (dir1) (dir2)
概念证明：
#!/bin/sh
#create our test
mkdir -p /tmp/a/b
echo "test" >> /tmp/a/c
mkdir -p /tmp/a/d/e
echo "blah" >> /tmp/a/d/e/f #only exists here
mkdir -p /tmp/q/b
echo "testing" >> /tmp/q/c #/tmp/a/c shouldnt match
mkdir -p /tmp/q/d/e
echo "blah" >> /tmp/q/d/e/g #only exists here
diff -rq /tmp/a /tmp/q
结果：
#!/bin/sh
#create our test
mkdir -p /tmp/a/b
echo "test" >> /tmp/a/c
mkdir -p /tmp/a/d/e
echo "blah" >> /tmp/a/d/e/f #only exists here
mkdir -p /tmp/q/b
echo "testing" >> /tmp/q/c #/tmp/a/c shouldnt match
mkdir -p /tmp/q/d/e
echo "blah" >> /tmp/q/d/e/g #only exists here
diff -rq /tmp/a /tmp/q
