如何对目录中的所有文件执行grep操作? [英] How to perform grep operation on all files in a directory?

问题描述

使用xenserver，我想对目录中的每个文件执行一条命令，从命令输出中提取一些内容并将其附加到文件中.

Working with xenserver, and I want to perform a command on each file that is in a directory, grepping some stuff out of the output of the command and appending it in a file.

我清楚要使用的命令以及如何根据需要grep输出字符串.

I'm clear on the command I want to use and how to grep out string(s) as needed.

但是我不清楚的是我如何在每个文件上执行此命令，然后转到下一个，直到找不到更多文件.

But what I'm not clear on is how do I have it perform this command on each file, going to the next, until no more files are found.

推荐答案

grep $ PATTERN * 就足够了.默认情况下，grep会跳过所有子目录.但是，如果要通过它们进行grep操作，请使用 grep -r $ PATTERN * .

grep $PATTERN * would be sufficient. By default, grep would skip all subdirectories. However, if you want to grep through them, grep -r $PATTERN * is the case.
