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 :-)
