Replace a string with another string in all files below my current dir
提问by KRB
How do I replace every occurrence of a string with another string below my current directory?
如何用当前目录下的另一个字符串替换每个出现的字符串？
Example:I want to replace every occurrence of www.fubar.comwith www.fubar.ftw.comin every file under my current directory.
示例：我想替换当前目录下每个文件中所有出现的www.fubar.comwith www.fubar.ftw.com。
From research so far I have come up with
从研究到目前为止，我想出了
sed -i 's/www.fubar.com/www.fubar.ftw.com/g' *.php

You're on the right track, use findto locate the files, then sedto edit them, for example:
您在正确的轨道上，用于find定位文件，然后sed编辑它们，例如：
find . -name '*.php' -exec sed -i -e 's/www.fubar.com/www.fubar.ftw.com/g' {} \;
Notes
笔记
- The
.means current directory - i.e. in this case, search in and below the current directory. - For some versions of
sedyou need to specify an extension for the-ioption, which is used for backup files. - The
-execoption is followed by the command to be applied to the files found, and is terminated by a semicolon, which must be escaped, otherwise the shell consumes it before it is passed to find.
- 该
.方法的当前目录-即，在这种情况下，在搜索和下面的当前目录。 - 对于某些版本，
sed您需要为该-i选项指定一个扩展名，用于备份文件。 - 该
-exec选项后跟要应用于找到的文件的命令，并以分号终止，必须对其进行转义，否则 shell 在将其传递给 find 之前将其消耗掉。

If there are no subfolders, a simpler to remember way is
如果没有子文件夹，一个更简单的记忆方法是
replace "www.fubar.com" "www.fubar.ftw.com" -- *
where * can also be a list of files
其中 * 也可以是文件列表
from the manual:
从手册：
Invoke replace in one of the following ways:
shell> replace from to [from to] ... -- file_name [file_name] ... shell> replace from to [from to] ... < file_name
通过以下方式之一调用替换：
shell> replace from to [from to] ... -- file_name [file_name] ... shell> replace from to [from to] ... < file_name
If you have hidden files with a dot you can add those to *with
如果您已经隐藏以点文件，您可以添加到那些*与
shopt -s dotglob
If you only have one depth of subfoldersyou can use */*instead of *
如果您只有一个深度的子文件夹，则可以使用*/*而不是*
replace "www.fubar.com" "www.fubar.ftw.com" -- */*
