在linux中查找2个目录之间的差异

嗨，大家好，

      I was trying to find the difference between two directories, dir structure as follows.

DIR1 /子目录/ file.txt的

DIR2 /子目录/ nffile.txt

当我尝试使用“diff -r dir1 dir2”时，它仅显示文件中的内容差异，但我希望新增文件的实习生。

我们可以使用“diff”命令找到这些目录之间的差异。

尝试使用--brief选项，如：

$ diff --recursive --brief dir1 dir2
Only in dir1/dir1: file1
Only in dir2/dir1: file2
Only in dir1: dir2
$

---

Alt.1 - 使用差异

diff <(ls dir1) <(ls dir2)

Alt.2 - 不使用差异的脚本

 for i in /my/directory/*; do
    name=$(basename "$i")
    if [[ ! -e "/my/other/directory/$name" ]]; then
       echo $name not found in other directory
    fi
 done

---

diff -qrN dir1 dir2

如果其中一个目录的名称可能与参数混淆

diff -qrN -- -f -z

其中-f和-z实际上是目录名称

删除q参数以获得有关更改内容的更多详细信息。 如果你想更详细地使用以下内容

diff -rupN -- dir1 dir2
