UNIX for Advanced & Expert Users

Hi,

I posted this over at Macnn and was redirected here... I'm not a unix programmer at all, but I have some backup if needed. Thanks in advance for any input.

Is there a command for the osX terminal that will list sequentially numbered groups of file as one line instead of individually, while listing other files and directories correctly?

Meaning that a group of files:

image.001.tif
image.002.tif
image.003.tif
image.004.tif
image.005.tif

would be listed as

image.001-005.tif


and a dir with other files and dirs:

image.001.tif
image.002.tif
image.003.tif
image.004.tif
image.005.tif
dir01/
dir02/
imageB.tif

in it would be:

image.001-005.tif
dir01/
dir02/
imageB.tif

?

Wold love to have this...

Thanks,
KM

Surely this can be done better, but it was a quick job
