Hi all,

I want to replace text 'DEF' for those files containing text 'ABC'.

I can only locate the files containing text 'ABC', but I don't know how to replace the text 'ABC' with 'DEF'.

I use the following command to locate the files containing 'ABC'

find . -exec grep -l 'ABC' {} \;

But don't know how to replace it.

Thanks in advance.

Regards
Wilson

sed 's/ABC/DEF/g' < inputfile > tmpfile
mv tmpfile inputfile
