Think I went on that same course, on another continent. Or maybe it
had become Netware Unix by then. Netware had something to do with it,
ISTR.

Two modes: beep repeatedly, and break everything. :-)

I've got a java prog that starts via a bash script. For reasons outside my control, it sometimes needs stopping and restarting – I can check if this is necessary using a cron job.

So, how do I stop and restart the main script (from the cron task) ?

Cheers.

Surely your cron job can just call a bash script, which can then do whatever you want?

Yes – but how do I stop the process?

Subject: [bristol] Bulk Exif date insertion - Perl error

Hi,

I have started to scan old transparencies onto my PC and have bulk
renamed them OK with "Thunar" file manager.
Before I import them I want to insert exif dates on groups of images.

I have been trying exiv2 with a perl script to bulk insert. It does seem
to work but throws up errors as the originator expected but I am curious
to know where the problem is and if I can eliminate it!

I know very little about perl but can get the idea of what the script does.

Can anyone enlighten me as to if the problem is with exiv2 or the script
and how I could make it work better?

References:

Actual Script:

#!/usr/bin/perl -w
#
# ADDING DATES TO SCANNED PHOTOS OR NEGATIVES
#
# Kim Briggs 2009-12 http://kimbriggs.com
#
# Script uses the exiv2 program http://www.exiv2.org/
# to add EXIF date and metadata to JPGS (and rename with new timestamp).
#
# Process ONE ROLL of film at a time (59 pics max).
# Numbering sequence is from NOON, i.e., 120100 to 125900.
#
# Reference of EXIF format: Date Taken: 2009:10:07 15:24:02
# ModifyDate=DateTime(EXIFspec)
# CreateDate=DateTimeDigitized(EXIFspec)
# DateTimeOriginal(ExifIFD)
# exiv2 -pt = print all the exif tags to screen
#

print "Enter Your Name: ";
chomp($my_name = <>);

print "Enter the Year(YYYY): ";
chomp($my_year = <>);

print "Enter the Month(MM): ";
chomp($my_month = <>);

print "Enter the Day(DD): ";
chomp($my_day = <>);

# Load all jpgs into an array. Use the same suffix for all files to
preserve your order.
# There will be an error message about the suffix you didn't use. Ignore it.
@pix = `ls *.JPG *.jpg`;

$my_count = 0;

foreach $pix (@pix) {

if ($my_count < 10) {$my_count="0$my_count";}

print "Processing photo: ".$pix;
# Use the program exiv2 to process EXIF metadata and rename the file
with timestamp

system("exiv2 -M'set Exif.Image.Artist $my_name $my_website' $pix");

system("exiv2 -M'set Exif.Image.DateTime $my_year:$my_month:$my_day
12:$my_count:00' $pix");

system("exiv2 -M'set Exif.Photo.DateTimeOriginal
$my_year:$my_month:$my_day 12:$my_count:00' $pix");

system("exiv2 -M'set Exif.Photo.DateTimeDigitized
$my_year:$my_month:$my_day 12:$my_count:00' $pix");

# Comment out the line below with a "#" symbol to AVOID RENAMING the file.

system("exiv2 -r %Y_%m%d_%H%M%S $pix");

$my_count = int($my_count) + 1;
}

http://www.exiv2.org/
http://kimbriggs.com/computer/add-exif-date-scanned-photo-negative

FYI when its run, it first complains about "website'$pix" only occurring
once, then asks for name etc. then actuall runs and does the job OK.

So another question is where does it get "my_website $pix"!?

Thanks
