grep:警告:递归目录循环

Question

我正在使用Xshell对Unix服务器进行ssh，并试图搜索包含特定文本的文件。

我使用的命令是：grep -ilr "blah_blah_text" ./

它找到了我要找的东西，但它也发出了以下警告：

警告：./svn/pages/dvorak/xhtml/mh370/ocean/dvorak/found:递归目录循环 警告：./svn/pages/dvorak/xhtml/mh370/ocean/dvorak/testing/sea:递归目录循环 警告：./svn/pages/dvorak/xhtml/mh370/ocean/dvorak/testing/found:递归目录循环 警告：./svn/pages/dvorak/xhtml/mh370/ocean/testing/dvorak/found:递归目录循环 警告：./svn/pages/dvorak/xhtml/mh370/ocean/testing/dvorak/monday:递归目录循环 警告：./svn/pages/dvorak/xhtml/mh370/ocean/testing/found:递归目录循环 警告：./svn/pages/dvorak/xhtml/mh370/testing/dvorak/ocean/sea:递归目录循环 警告：./svn/pages/dvorak/xhtml/mh370/testing/dvorak/ocean/monday:递归目录循环 警告：./svn/pages/dvorak/xhtml/mh370/testing/dvorak/monday:递归目录循环 警告：./svn/pages/dvorak/xhtml/mh370/testing/ocean/dvorak/found:递归目录循环 警告：./svn/pages/dvorak/xhtml/mh370/testing/ocean/dvorak/monday:递归目录循环 警告：./svn/pages/dvorak/xhtml/mh370/testing/ocean/monday:递归目录循环 警告：./svn/pages/gulf/xhtml/qwerty/ocean/dvorak/found:递归目录循环 警告：./svn/pages/gulf/xhtml/qwerty/ocean/dvorak/testing/sea:递归目录循环 警告：./svn/pages/gulf/xhtml/qwerty/ocean/dvorak/testing/found:递归目录循环 警告：./svn/pages/gulf/xhtml/qwerty/ocean/testing/dvorak/found:递归目录循环 警告：./svn/pages/gulf/xhtml/qwerty/ocean/testing/dvorak/monday:递归目录循环 警告：./svn/pages/gulf/xhtml/qwerty/ocean/testing/found:递归目录循环 警告：./svn/pages/gulf/xhtml/qwerty/dvorak/ocean/sea:递归目录循环 警告：./svn/pages/gulf/xhtml/qwerty/dvorak/ocean/testing/sea:递归目录循环 警告：./svn/pages/gulf/xhtml/qwerty/dvorak/ocean/testing/found:递归目录循环 警告：./svn/pages/gulf/xhtml/qwerty/dvorak/testing/sea:递归目录循环 警告：./svn/pages/gulf/xhtml/qwerty/dvorak/testing/ocean/sea:递归目录循环 警告：./svn/pages/gulf/xhtml/qwerty/dvorak/testing/ocean/monday:递归目录循环 警告：./svn/pages/india/xhtml/abcd/testing/dvorak/ocean/sea:递归目录循环 警告：./svn/pages/india/xhtml/abcd/testing/dvorak/ocean/monday:递归目录循环 警告：./svn/pages/india/xhtml/abcd/testing/dvorak/monday:递归目录循环 警告：./svn/pages/india/xhtml/abcd/testing/ocean/dvorak/found:递归目录循环 警告：./svn/pages/india/xhtml/abcd/testing/ocean/dvorak/monday:递归目录循环 警告：./svn/pages/india/xhtml/abcd/testing/ocean/monday:递归目录循环 警告：./svn/pages/india/xhtml/abcd/dvorak/ocean/sea:递归目录循环 警告：./svn/pages/india/xhtml/abcd/dvorak/ocean/testing/sea:递归目录循环 警告：./svn/pages/india/xhtml/abcd/dvorak/ocean/testing/found:递归目录循环 警告：./svn/pages/india/xhtml/abcd/dvorak/testing/sea:递归目录循环 警告：./svn/pages/india/xhtml/abcd/dvorak/testing/ocean/sea:递归目录循环 警告：./svn/pages/india/xhtml/abcd/dvorak/testing/ocean/monday:递归目录循环

这些信息是什么意思？

你必须从你的grep中排除符号链接，它们是这个警告的原因。您应该尝试首先使用find：

find ./ -type f -exec grep -il "blah_blah_text" {} \;

当您首先使用find时，可以在grep中省略-r，因为find已经是递归的。
