Diff命令返回目录之间的“Only In”差异

Question

我正在使用diff命令来比较两个Wordpress目录（一个最近被漏洞攻击，另一个是普通拷贝）。在我的差异命令的迷雾中，我有很多不同，但很少“仅在”

例如：

Files public_html/wp-includes/widgets.php and public_html 2/wp-includes/widgets.php differ
Files public_html/wp-includes/wp-db.php and public_html 2/wp-includes/wp-db.php differ
Files public_html/wp-includes/wp-diff.php and public_html 2/wp-includes/wp-diff.php differ
Files public_html/wp-login.php and public_html 2/wp-login.php differ
Only in public_html 2/: wp-options.php
Files public_html/wp-signup.php and public_html 2/wp-signup.php differ

我关心'Only in'输出。解决这个问题的最佳方式是什么？

Answer 1

将输出传递给类似grep的命令以对其进行过滤。给定目录a /和b /：

diff -qr a/ b/ | fgrep 'Only in'

或者，如果您希望跳过区分大小写，可以尝试：

diff -qr a/ b/ | fgrep -i 'Only in'
