Search and replace text in all files of a linux directory
提问by Yarin
I have a website directory where I need to change all hardcoded links from one domain to another. Looking for a single (grep? sed?) bash command that will allow me to change all occurrences of text in all files in the directory?

The following will do it:
以下将做到这一点：
sed -i 's/old_link/new_link/g' file...
Don't forget to escape any slashes, dots, and any other regex special chars in the link addresses with a backslash.
不要忘记使用反斜杠对链接地址中的任何斜杠、点和任何其他正则表达式特殊字符进行转义。
