date2name 2017.12.08

Handling time-stamps and date-stamps in file names

This Python script adds, removes, and manages date- and time-stamps in file names.

2013-05-09 a file name with ISO date stamp in name – tag1.jpg

2013-05-09T16.17 file name with time stamp – tag3.csv

Usage:

date2name [options] file …

Per default, date2name gets the modification time of matching files and directories and adds a datestamp in standard ISO 8601+ format YYYY-MM-DD (http://datestamps.org/index.shtml) at the beginning of the file- or directoryname. If an existing timestamp is found, its style will be converted to the selected ISO datestamp format but the numbers stays the same. Executed with an examplefilename “file” this results e.g. in “2008-12-31_file”. Note: Other that defined in ISO 8601+ the delimiter between hours, minutes, and seconds is not a colon but a dot. Colons are causing several problems on different file systems and are there fore replaced with the (older) DIN 5008 version with dots.
