For a sorting script, I'm currently searching for a method to get file creation date and time as exactly as possible. The best resolution I could get was seconds. In case more than one file is created within the same second, it doesn't work precisely enough. It should work from sh script. For the purpose of preparing the sort list (that will be sorted and then be used as a template for renaming the files with a prefix and a counter), I'm using the "stat" program which creates output like this: % stat -f "%N %B" -t "%Y-%m-%d_%H:%M:%S" 1.txt 1.txt 2012-01-03_12:12:12 It's also possible to use the Epoch time format, but it doesn't provide a solution better than seconds: % stat -f "%N %B" -t "%s" 1.txt 1.txt 1325589132 I've read the manuals for stat as well as for strftime (which is the facility stat's -t parameter addresses), but found nothing that is more precise than seconds. Does anyone have a suggestion how to precisely determine the order files have been created? -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
