Script to update 'created on' timestamp

Will have a look at the weekend hopefully

I'll have a crack at weekend too - Unix flavours despite being fairly consistent often isn't on stuff like this, once spent ages cursing RHEL cos it didn't have 'grep -p' like in AIX. Plus I just bagged a HP-UX box I wanna play with!

I found that, but couldn't get it to work on my Linux box (which is very out of date now), so didn't post it.

The next step for you to consider is to go through the renamed files and take the new modified date and use that to correct the EXIF data in the image file

In case anyone else is ever looking for something similar, I've pinched this off askubuntu and it works fine on my MBP. Just add in the number of days you want to shift the timestamp by (73days in the case below).

Note: this only updates the 'modified on' if it's later than 'created on' but I'll fiddle when I get the chance.

Ta all.



#!/bin/bash

# find specific files
files=$(find . -type f -name '*.jpg')

# use newline as file separator (handle spaces in filenames)
IFS=$'\n'

for f in ${files}
do
# read file modification date using stat as seconds
# adjust date using date and print in correct format
# change file time using touch
touch -t $(date -v +73d -r $(stat -f %m "${f}") +%Y%m%d%H%M.%S) "${f}"
done

If a Unix system (or Unix-like) 'touch -t timestamp_you_want filename(s) - wildcards/regex works in the filename bit.

eg: touch -t 201409161030 pic*.jpg

for a timestamp of 16th of Sept 2014 at 10:30am......

EDIT: reread - this won't do exactly what you want, you'd need to do some awk/sed/grep'ing on a listing to squirt into a for loop.

Cheers Stek.

Maybe a long shot but thought I'd ask.

Background: Every year when we go on hols I forget to update the current date/time on the camera, which means that all the image files have a created on of 01 Jan 2010 + the holiday duration.

I'd like a script/prog/app that I can run in a directory that will update the created on timestamp relative to a specified value. i.e it replaces 01/01/2010 + holiday elapsed time with 16/09/2014 + HET

Any ideas?

TIA

What operating system?

Mac, Win or Ubuntu.

Don't know whether this still works, but it looks like it might do the trick - BulkFileChanger: Change date/time/attributes of multiple files

Cheers Faq. Will take look.
