17 Jul 2012 Rename AVCHD files using Exiftools
Simple bash script to rename AVCHD/MTS/MOV files to match their recording date and time.
#!/bin/bash
if [ -z "$1" ]; then
echo "Usage: ./rename_video.sh FILETYPE" 1>&2
echo "Example: ./rename_video.sh *.MTS" 1>&2
exit 1
fi
for x in "$@"
do
exiftool '-FileName<DateTimeOriginal' -d %Y%m%d_%H%M_%%f.%%e "$x"
done
The resulting files will be named like YYYYMMDD_HHMM_BASENAME.ext ie 20120703_1635_05600.MTS
Exiftools can also be used to perform the renaming process in Windows as well using a command window
# exiftool "-FileName<DateTimeOriginal" -d %Y%m%d_%H%M_%%f.%%e *.MTS
This script has been tested on Canon Legria and on Panasonic HDC-SD800 video camera MTS-files and Nikon D7000 MOV-files with great success.

10 Nov 2011 Remove white space from file names
This is a one liner to remove white space in filenames using a linux console
# rename 'y/ /_/' *
You could also do this the other way, remove underscore with space
# rename 'y/_//' *

24 Oct 2008 Rename file name suffix to uppercase or lowercase
This is a little oneliner to rename a files suffix from/to uppercase/lowercase.
Rename a jpg suffix to JPG in the current folder
# find -name "*.jpg" | while read a; do mv "$a" "${a%%.jpg}.JPG" ; done
The work JPG can be replaced by any other word :)

02 Sep 2008 Rename files by wildcard pattern and correct the EXIF timestamp metadata
This is a little script I’ve written to correct all my image files since the EXIF timestamp information is one hour out of sync. The filenames have been renamed to comply to the EXIF information and has to be renamed again because of the one hour scew. The filename can look something like this 20080102-1201_DSC_0910.JPG where the name is built up like YYYYMMDD-HHMM_Original_Filename.JPG
Remember to backup your imagefiles before you continue. You have been warned!
Rename files using wildcard pattern
This is the files we are going to rename
20080102-1201_DSC_0910.JPG 20080105-1923_DSC_1006.JPG 20080111-1220_DSC00189.JPG 20080122-0929_DSC00190.JPG
The mmv command is a command that lets you move/copy/append/link multiple files by wildcard patterns. It can be installed in Debian (or Debian based distributions like Ubuntu) by issuing the command
# aptitude install mmv
Now rename the files back to their original name
# mmv "*_DSC*" "DSC#2"
The result after this operation looks like this
DSC_0910.JPG DSC_1006.JPG DSC_1179.JPG DSC_1302.JPG DSC_1587.JPG
Correct the EXIF timestamp using exiv2
Next adjust the EXIF information stored in the image files to fix the one hour difference. This can be done using different EXIF tools like exiftool, but I will show you how it can be done using jhead and exiv2. The advantage with exiv2 is that it can also handle Nikon NEF files while jhead only can prosess JPG.
The current timestamp can be determined as follows
# exiftool DSC_0910.JPG | grep "File Mo"
The result in this case is
File Modification Date/Time : 2008:01:02 08:34:09
Adjust EXIF time info one hour forward using exiftool
# exiftool -AllDates+=1 DSC_0910.JPG
Other tools that could have done the job
Adjust EXIF time info one hour forward using jhead
# jhead -ta +1 DSC_0910.JPG
Install the jhead package using aptitude as mentioned earlier for the mmv package
Adjust EXIF time info one hour forward using exiv2
# exiv2 ad -a 1 DSC_0910.JPG
Rename files back to YYYYMMDD-HHMM_Original_Filename.JPG
It is now time to rename the files back to the YYYYMMDD-HHMM_Original_Filename.JPG format I used before this operation. This operation has been describe in a previous post named Rename image files according to EXIF date
exiv2 -r'%Y%m%d-%H%M_:basename:' rename $(ls D*)
The script
#!/bin/bash -x # Needed software: # exiftool # exiv2 # mmv # Script tested on Nikon D80 and Sony Cybershot DSC-W12 files # Make a printout of how the files look like now ls -l > repair_name_and_exif_before.txt # Rename files to remove date formatting back to original name mmv "*_DSC*" "DSC#2" # Change EXIF info on JPG files (order is important) exiftool -overwrite_original -AllDates+=1 D*.JPG # Preserve date/time of original file when writing exiftool -overwrite_original '-DateTimeOriginal>FileModifyDate' D*.JPG # Change EXIF info on NEF files (order is important) exiftool -overwrite_original -AllDates+=1 '-DateTimeOriginal>FileModifyDate' D*.NEF # Preserve date/time of original file when writing exiftool -overwrite_original '-DateTimeOriginal>FileModifyDate' D*.NEF # Rename files back to date formatting (YYYYMMDD-HHMM_Filename) based on the new EXIF info exiv2 -r'%Y%m%d-%H%M_:basename:' rename $(ls D*) # Make a printout of how the files look like after conversion ls -l > repair_name_and_exif_after.txt
