hello All,
I have photos from my mobile phone, an old Nokia 6021, and readily get them onto the PC. The problem is the naming, the first eight characters are the date, two digits for the day, two for the month then four for the year. I wish to reorder them to be year, month and then day. That portion of the filename is then followed by brackets with a three digit sequence number for the second and subsequent photos on the day. it would be good to add the brackets with three zeros when not present. That is followed by a period and the jpg extension.
This will let me order by date when viewing in Image Viewer, and a relatively sane sorting of the filenames. There are something over 450 images in the directory that I wish to edit the names of, so better to get the PC to do the repetitive work.
My shell programming, and the like, are rusty, what there is of such skills. I would appreciate some assistance and pointers.
Regards,

Below is my answer to your problem although it probably will not suit without modifacation. I have a couple Of Nikons (a D700 and a D810) they produce filenames like DSC_0829.NEF. I wanted them to be in a Date and time format for the reasons you mentioned. I ended up with a filename like 20081106_132142-0829.png. I kept the cameras sequence number is the D700 is capable of around 6 frames per second, and this of course would produce identical file names for shots within the same second, The date and time comes from data within the image and is extracked by exiv2, using this garuntees the time is correct according to the camera. Cut here................................................. #! /bin/bash # this is a script to take the file names from the camera and rename them to Date and time of # creation # ls *.nef --color=never -l | cut -c 33-45,50-57 | tr '\040' '\137' #NAME=$(ls $1 --color=never -l | cut -c 33-45,50-57 | tr '\040' '\137') LIST=`ls --color=never *.nef` echo $LIST COUNTER=1 for i in $LIST do # echo $i # NAME=$(ls $i --color=never -l | cut -c 35-47,52-59 | tr '\040' '\137' | tr '\072' '\055') NAME1=$(ls $i --color=never -l | cut -c 52-59 | tr '\040' '\137' | tr -d '\072') NAME=$(exiv2 $i | grep timestamp | cut -c 19-37 | tr -d '\072' | tr '\040' '\137') echo $NAME-$NAME1 cp $i $NAME-$NAME1 done ------------------------------end cut------------------------------ Lindsay
