Find and replace string in all files and folders in a certain directory

Question

I have SSH access to a web hosting server. There are several thousand files, most of which contain the string 'Copyright ABC'.

I would like to change the string in the (and all files in the sub-folders) code of all of these files to 'Copyright XYZ' as our company has acquired the old site and we must change the footer.

Answer 1

使用find获取文件，然后使用xargs将它们与sed一起使用

find /your/path -type f -print0 | xargs -0 sed -i 's!Copyright ABC!Copyright XYZ!g'

Answer 2

find . -type f -exec sed -i 's/Copyright ABC/Copyright XYZ/g' {} +

Answer 3

我喜欢Perl派！

 find /your/path/ -type f -exec perl -p -i -e's/Copyright ABC/Copyright XYZ/g' {} \;
