Find and replace string in files recursively

This is the best option I have found so far: find . -type f -exec sed -i 's/foo/bar/g' {} +
foo is replaced with bar.

Also quite handy to be able to search and replace filenames.

find . -type f -name 'foo*' | while read FILE ; do
    newfile="$(echo ${FILE} |sed -e 's/foo/bar/')" ;
    mv "${FILE}" "${newfile}" ;
done

Also a useful thing is to search for strings within files: grep -rn '/path/to/somewhere/' -e "pattern"

Here for searching for strings in PDF-files: find /path -name '*.pdf' -exec sh -c 'pdftotext "{}" - | grep --with-filename --label="{}" --color "your pattern"' \;
