You might be better to crete two temporary reference files with the correct timestamp.

What criteria do you have for the search date(s)? If it is just today's files, then you could do something like:
Code:
my_ref_file="$(mktemp)"
touch -mt $(date '+%Y%m%d0000' "${my_ref_file}"                                    # Sets the file timestamp to the start of today
find . -type f -newer "${my_ref_file}" -exec grep "myword" {} /dev/null \;         # Search for files newer than the reference file modification time (set above)
rm "${my_ref_file}"                                                                # Just to be tidy

This will create you a marker file based on the current date, setting it to midnight (the 0000 at the end of the date command) Using that, you can find any files that are newer and search for them. For each file found, it then runs the grep with {} representing the file just found. The reason to add /dev/null to the end is so that grep sees two files and therefore prints the file names where it finds your string.

Does this help? You may need to add in a -maxdepth flag to suit your needs if there are subdirectories.


If you have a date range to collect files from or a particular day to search, you can create two reference files to mark the start and end of the range. You would then add a ! -newer "${second_ref_file}" to stop it finding anything that is too new.

Of course, this could be modified to set specific times by replacing the 0000 with a required time coding when touching a reference file if that is required, e.g. you just want a particular hour.



I hope that this is useful,
Robin
