NAME 
       sort - sort lines of text files

SYNOPSIS 
       sort [OPTION]... [FILE]...
       sort [OPTION]... --files0-from=F

DESCRIPTION 
       Write sorted concatenation of all FILE(s) to standard output.

       Mandatory  arguments  to  long  options are mandatory for short options
       too.  Ordering options:

       -b, --ignore-leading-blanks
	      ignore leading blanks

       -d, --dictionary-order
	      consider only blanks and alphanumeric characters

       -f, --ignore-case
	      fold lower case to upper case characters

       -g, --general-numeric-sort
	      compare according to general numerical value

       -i, --ignore-nonprinting
	      consider only printable characters

       -M, --month-sort
	      compare (unknown) < `JAN' < ... < `DEC'

       -n, --numeric-sort
	      compare according to string numerical value

       -R, --random-sort
	      sort by random hash of keys

       --random-source=FILE
	      get random bytes from FILE

       -r, --reverse
	      reverse the result of comparisons

       --sort=WORD
	      sort according to WORD: general-numeric -g,  month  -M,  numeric
	      -n, random -R, version -V

       -V, --version-sort
	      natural sort of (version) numbers within text

       Other options:

       --batch-size=NMERGE
	      merge at most NMERGE inputs at once; for more use temp files

       -c, --check, --check=diagnose-first
	      check for sorted input; do not sort

       -C, --check=quiet, --check=silent
	      like -c, but do not report first bad line

       --compress-program=PROG
	      compress temporaries with PROG; decompress them with PROG -d

       --files0-from=F
	      read  input  from the files specified by NUL-terminated names in
	      file F; If F is - then read names from standard input

       -k, --key=POS1[,POS2]
	      start a key at POS1 (origin 1), end it at POS2 (default  end  of
	      line)

       -m, --merge
	      merge already sorted files; do not sort

       -o, --output=FILE
	      write result to FILE instead of standard output

       -s, --stable
	      stabilize sort by disabling last-resort comparison

       -S, --buffer-size=SIZE
	      use SIZE for main memory buffer

       -t, --field-separator=SEP
	      use SEP instead of non-blank to blank transition

       -T, --temporary-directory=DIR
	      use  DIR	for temporaries, not $TMPDIR or /tmp; multiple options
	      specify multiple directories

       -u, --unique
	      with -c, check for strict ordering; without -c, output only  the
	      first of an equal run

       -z, --zero-terminated
	      end lines with 0 byte, not newline

       --help display this help and exit

       --version
	      output version information and exit

       POS  is	F[.C][OPTS],  where  F is the field number and C the character
       position in the field; both are origin 1.  If neither -t nor -b	is  in
       effect,	characters  in	a  field are counted from the beginning of the
       preceding whitespace.  OPTS  is	one  or  more  single-letter  ordering
       options,  which	override  global ordering options for that key.  If no
       key is given, use the entire line as the key.

       SIZE may be followed by the following multiplicative suffixes: % 1%  of
       memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y.

       With no FILE, or when FILE is -, read standard input.

       ***  WARNING  ***  The locale specified by the environment affects sort
       order.  Set LC_ALL=C to get the traditional sort order that uses native
       byte values.

The problem: You have a series of photos where the time is offset from the correct time but is still correct in relation to each other.

Here are a few of the times that I’ve needed to do this:
- Changing the battery on my camera switched to a default date.
- I wanted to synchronize the time on my camera to a GPS track so the photos matched the timestamped coordinates.
- At a family event where images from different cameras were added together.

You can do edit the timestamp using a GUI and many photo manipulation applications like the GIMP support metadata editing. For example on KDE:

    gwenview -> plugins -> images -> metadata -> edit EXIF 

The problem is that this gets tiresome after a few images, and anyway the times are correct in relation to each other – I just need to add or subtract a time correction to them en masse.

The answer: exiv2 – Image metadata manipulation tool. It is a program to read and write Exif, IPTC and XMP image metadata and image comments.

user@pc:~$ exiv2 *.jpg

Exif comment    :

The trick is to pick a image where you can that figure out what the time was and work out the time offset. In my case I needed to adjust the date forward by six months and four days while changing the time back by seven hours. I used the command exiv2 -O 6 -D 4 -a -7 *.jpg

-a time
    Time adjustment in the format [-]HH[:MM[:SS]].
    This option is only used with the 'adjust' action. Examples:
        1 adds one hour,
        1:01 adds one hour and one minute,
        -0:00:30 subtracts 30 seconds.
-Y yrs
    Time adjustment by a positive or negative number of years, for the 'adjust' action.
-O mon
    Time adjustment by a positive or negative number of months, for the 'adjust' action.
-D day
    Time adjustment by a positive or negative number of days, for the 'adjust' action.

When we run this we can see that the timestamp has now changed.

user@pc:~$ exiv2 *.jpg | grep timestamp
Image timestamp : 2009:06:11 08:12:59

That’s it. Remember this is the end of the conversation – to give feedback you can either record a show for the HPR network and email it to admin@hackerpublicradio.org or write it on a post-it note and attach it to the windscreen of Dave Yates’s car as he’s recording his next show.
