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?
答
下面将做到这一点：
sed -i 's/old_link/new_link/g' file...
不要忘了逃跑的斜线，点，并在链接地址的任何其他正则表达式特殊字符用反斜杠。
Don't forget to escape any slashes, dots, and any other regex special chars in the link addresses with a backslash.
