Help with multiple file rename - change case of part of file name

Hi there,

I hope someone can help me with this problem :

I have a directory (/var/www/file/imgprofil) which contains about 10000 JPG files. They have a naming convention thus :

prefix-date-key-suffix.jpg

they all have the prefix p-20050608-
then AAAA is a 4 letter code
the suffix is either -g / -v / -m or no suffix
the file extension is always .jpg

sample :

p-20050608-AFWC-g.jpg
p-20050608-AFWC-m.jpg
p-20050608-AFWC-v.jpg
p-20050608-AFWC.jpg
p-20050608-AFWD-g.jpg
p-20050608-AFWD-m.jpg
p-20050608-AFWD-v.jpg
p-20050608-AFWD.jpg

My problem is that some of the files have 1 or more lower case letters in the 4 letter code, so they are like this :

p-20050608-Ajyd-g.jpg
p-20050608-Ajyd-m.jpg
p-20050608-Ajyd-v.jpg
p-20050608-Ajyd.jpg
p-20050608-Ajyw-g.jpg
p-20050608-Ajyw-m.jpg
p-20050608-Ajyw-v.jpg
p-20050608-Ajyw.jpg

Now, Unix being the case sensitive angel that it is Smilie

I need to transform these lowercase "keys" filenames into uppercase, so the sample would be :

p-20050608-AJYD-g.jpg
p-20050608-AJYD-m.jpg
p-20050608-AJYD-v.jpg
p-20050608-AJYD.jpg
p-20050608-AJYW-g.jpg
p-20050608-AJYW-m.jpg
p-20050608-AJYW-v.jpg
p-20050608-AJYW.jpg

While of course keeping the lowercase prefix (p-) and suffix (-g /-m / -v) and the lowercase file extension (.jpg)

I hope this is clear and that someone can help with this,

Thanks,

Steve

pfsinhdrgen(1)						      General Commands Manual						    pfsinhdrgen(1)

NAME

       pfsinhdrgen - Create a pfs stream with different exposures defined by hdrgen script.

SYNOPSIS

       pfsinhdrgen <sample.hdrgen>

DESCRIPTION

       This  program  reads  files  defined  in  given	hdrgen script and outputs them in a PFS stream. Each frame has a tag BV with corresponding
       brightness value (APEX standard). Larger BV corresponds to less exposure (darker image), necessary to capture a bright scene.

       The generated PFS stream is to be used with photo-metric calibration software and with generators of HDR images.

       HDRGEN script file is a plain text file in  which  each	line  contains:  <path_to_an_image>  <inverse_of_exposure_time_in_seconds>  <aper-
       ture_size> <iso_speed> 0

       In  most  cases	it  is	convenient to use the jpeg2hdrgen program to create such a file automatically. In case it could not parse the exif
       information from jpeg files, it is necessary to create this file by hand. Below are the sample contents of such file:

       <--- cut here: sample.hdrgen /var/tmp/images/img08.jpg 4 2.8 100 0 /var/tmp/images/img09.jpg 58.8235 2.8  100  0  /var/tmp/images/img10.jpg
       76.9231 2.8 100 0 /var/tmp/images/img11.jpg 322.581 2.8 100 0 /var/tmp/images/img12.jpg 400 2.8 100 0 <--- cut here: sample.hdrgen

EXAMPLES

       pfsinhdrgen sample.hdrgen | pfsview

	      View exposures defined in sample.hdrgen script.
