Question

How can I replace text with other text using GNU sed? I was hacked and am just trying to see if I can remove some of the code that was placed into my php files. The text is of the

eval(base64_decode('blah'));

variety. All of them are identical, I would just like to find and replace all of them in all files. I have tried some commands, but they either needlessly alter and damage text in the files or simply fail to launch at all.

Answer 1

sed -i 's/text/other text/g' filename

(sed -i "s/eval(base64_decode('blah'))/huh/g" filename in your case).
