Hi, That sounds like the correct behaviour to me. It sounds like you are expecting "newer" to mean the-same-as-or-newer when it just means "newer" (i.e. ">=" rather than ">" as documented). The manual entry says:-newer reference Time of the last data modification of the current file is more recent than that of the last data modification of the reference file. -newerXY reference Succeeds if timestamp X of the file being considered is newer than timestamp Y of the file reference. It says "more recent than" and "newer". Both say "greater than" to me.
Right, all -newer options mean really "greater", i.e., not "greater or equal", and there's no option to check for equality, unfortunately.
Actually, forget all that. Since you are using -newermt, it just requires that find's time specification notation supports nsec and it looks like it does: https://www.gnu.org/software/findutils/manual/html_mono/find.html#Date-input-formats Shows this example: $ date --rfc-3339=ns # --rfc-3339 is a GNU extension. 2022-11-14 21:02:42.000000000-05:00 So maybe you can do: find . -newermt '2009-12-31 23:59:59.999999999-05:00' adjusted for your own timezone. I just checked it and it worked. Yay! $ touch -m -d "2010-01-01 00:00:00" example.txt $ find example.txt -newermt '2009-12-31 23:59:59.999999999+11:00' example.txt
Nice suggestion, thanks. This topic also reminds me that -newerXY does not yet show up in --help output. The attached fixes it, plus a minor typo fix with the other patch. Pushing soon. Have a nice day, Berny
