moin moin,


Looking to change some file dares to 14 hours later than the current file
date/time stamps (they are NOT all the same).  I was thinking some form of
the -d option would work but nothing I have tried works-

$ date; touch -d "$( date -d "+14 hours" +%Y%b%d )" /tmp/fred; ls -l
/tmp/fred Fr 29. Mär 16:57:45 MST 2013
-rw-r--r-- 1 lufthans lufthans 0 2013-03-30 01:13 /tmp/fred

The "+14 hours" only works with GNU date, but that's what we get on
GNU/Linux. BSD date really didn't like it :).

ciao,

This is close but not quite.  Maybe I could have explained it better.  I have taken a LOT if video clips here in Thailand.  Unfortunately, the camera clock was still set for Arizona time until several days into the trip.  Now that I have fixed that I want to re-timestamp the first 100 or so to have the timestamp adjusted +14 hours.  Here is what I get from der.Hans' script:

    larry@sunfish:~/tempwork$ ls -l target; date; touch -d "$( date -d "+14 hours" +%Y%b%d )" target; ls -l target
    -rw-rw-r-- 1 larry larry 0 Mar 24 18:18 target
    Fri Mar 29 23:55:49 MST 2013
    touch: invalid date format `2013Mar30'
    -rw-rw-r-- 1 larry larry 0 Mar 24 18:18 target
    larry@sunfish:~/tempwork$


I can fix the date format I believe, but the target's timestamp should end up being Mar 25 08:18, not Mar 30 13:55.  The reason I want a script or compound command to do it is so i don't have to figure out the +14 hours 100+ times and issue 100+ touch commands.

Thanks, I hope I can get the timestamp extracted to a variable and use that to replace the date command (if I don't fall asleep first :-)
