How can I find & replace text in HTML, htm, PHP and txt files on a Linux server?

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.

Look at the `sed` command, or maybe `perl` or `awk`. http://stackoverflow.com/questions/12663501/find-string-and-replace-line-in-linux http://stackoverflow.com/questions/8384809/replace-pattern-in-text-file for starters. — Andy Lester, Dec 16 '12 at 05:58

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
