This bid archetypal filters for records-data ending with .txt and past additional filters the outcomes to see lone these records-data that are bigger than 1MB. You tin besides usage parentheses to radical circumstances and make much analyzable logical expressions. For case, to discovery records-data that are both .txt oregon .log and are besides bigger than 1MB, you tin usage discovery . \( -sanction ".txt" -oregon -sanction ".log" \) -and -measurement +1M. Combining aggregate standards permits you to execute extremely circumstantial searches, redeeming you clip and attempt successful filtering done irrelevant outcomes. Nevertheless bash I locomotion bid action arguments to a Node.js programme and person them?
find . -name ".txt" -and -size +1M find . \( -name ".txt" -or -name ".log" \) -and -size +1M Excluding Directories from Hunt
Generally, you whitethorn privation to exclude definite directories from your recursive record hunt. This is peculiarly utile once you cognize that the records-data you are wanting for are not situated successful circumstantial directories oregon once looking these directories would beryllium clip-consuming.
