为什么不找** **发现了什么？ [英] Why doesn't **find** find anything?

问题描述

我要找的shell脚本安装在我的系统上的文件，但发现不起作用：

I'm looking for shell scripts files installed on my system, but find doesn't work:

$ find /usr -name *.sh

不过，我知道有一吨的脚本在那里。例如：

But I know there are a ton of scripts out there. For instance:

$ ls /usr/local/lib/*.sh
/usr/local/lib/tclConfig.sh  
/usr/local/lib/tkConfig.sh

为什么不发现工作

推荐答案

尝试引用通配符：

$ find /usr -name \*.sh

或

$ find /usr -name '*.sh'

如果你碰巧有一个匹配的文件*。SH 在当前工作目录，通配符会发现看到它之前扩大。如果你碰巧有一个在你的工作目录中名为tkConfig.sh文件，在找到命令将扩展为：

If you happen to have a file that matches *.sh in the current working directory, the wildcard will be expanded before find sees it. If you happen to have a file named tkConfig.sh in your working directory, the find command would expand to:

$ find /usr -name tkConfig.sh

这将只找到名为tkConfig.sh文件。如果你有一个匹配多个文件的 * SH 后，你会得到从语法错误的找到：

which would only find files named tkConfig.sh. If you had more than one file that matches *.sh, you'd get a syntax error from find:

$ cd /usr/local/lib
$ find /usr -name *.sh
find: bad option tkConfig.sh
find: path-list predicate-list

再次原因是通配符扩展为两个文件：

Again, the reason is that the wildcard expands to both files:

$ find /usr -name tclConfig.sh tkConfig.sh

引述通配符prevents它被prematurely扩大。

Quoting the wildcard prevents it from being prematurely expanded.

另一种可能是的/ usr或它的一个子目录是符号链接。 发现通常不会跟随链接，所以你可能需要在 -follow 选项：

Another possibility is that /usr or one of its subdirectories is a symlink. find doesn't normally follow links, so you might need the -follow option:

$ find /usr -follow -name '*.sh'
