unix - Unix one-liner to extract substring from all files in a directory and subdirectories

Question

I'm looking for a UNIX one-liner that will output to a file all occurrences of NSLocalizedString (from that word to the end of the line) in all files in the current directory and all subdirectories. I've googled, but haven't found a solution.

Answer 1

find . -type f -exec fgrep NSLocalizedString {} \+ | \
    sed -e 's/^.*\(NSLocalizedString.*\)$/\1/' > ../your_output_file

Answer 2

find <directory> -type f -print | xargs grep NSLocalizedString | tee <outputfile> should do what you're looking for, if I understand the question right...
