如何在Linux服务器上查找和替换HTML，htm，PHP和txt文件中的文本？

Question

I would like to know how to find and replace text in all HTML, htm, PHP and txt extension files on Linux server at hosting provider. I can do SSH.

Text to be found : http://mydomain.example.com

Text to be replaced with : http://otherdomain.example.com/MyDomain

Please give me exact command and it would be much helpful if it can prompt for confirmation before replacement.

Answer 1

Here's one way using sed and a for loop. Use the -i flag with mv to prompt before overwrite:

for i in *.html *.htm *.php *.txt; do sed 's%\(http://www\.\)\(MyDomain\)\(\.com\)%\1OtherDomain\3/\2%g' "$i" > tmp && mv -i tmp "$i"; done

Answer 2

sed -i 's/http:\/\/www.mydomain.com/http:\/\/www.otherdomain.com\/MyDomain/gi' *.txt *.html *.htm *.php
