 Preserve file timestamp in multifile string replace

 -I to grep ignores binary files,
 @ in sed works as separator for strings with /
 -r in touch uses existing file timestap as a reference

 $ grep -IR aaaa /somepath/ | awk -F: '{print $1}' | while read line; do touch -r $line /tmp/timeref; sed -i 's@aaaa@bbbb@' $line; touch -r /tmp/timeref $line; done
