Hi Folks

I am using the Nokia Camera application to take snaps and upload them to twitxr.com but the filenames are strangely formatted which makes finding and storing them differcult.

A file named 43_03_18-250208.jpg was taken on 25th February 2008 at 18:03:43.

I would like some help in writing a bash script to rename the same file to 20080225_180343.jpg so that the listing would be sorted automatically.

Any shell gurus in here wanna help ?

Thanks

Sed is built in, at least on my N810:

Code:

#!/bin/sh
# camrename.sh - Renames Nokia Camera application pictures
# v0.01 2008-02-26 by Jussi Ylänen

while test -n "$1"; do
  OLDNAME="$1"
  NEWNAME="`echo $OLDNAME | sed -re 's/([0-9]{2})_([0-9]{2})_([0-9]{2})-([0-9]{2})([0-9]{2})([0-9]{2})/20\6\5\4_\3\2\1/'`"

  if test "$OLDNAME" != "$NEWNAME"; then
    # Remove "echo" below to really rename...
    echo mv "$OLDNAME" "$NEWNAME"
  fi

  shift
done

In the sed expression above, each ([0-9]{2}) matces two digits and remembers them, later to be referenced with \n (where n is a digit). Year is assumed to be 2000 or greater.

Copy-paste the script, save it in /home/user as camrename.sh and do:

Code:

~ $ chmod +x camrename.sh

Usage:

Code:

~ $ camrename.sh /media/mmc1/camera/images/*

When you've tried the script and seen that it appears to handle the names correctly, edit the script and remove the extra echo to really enable file renaming. No warranty!
