Merge TIFF files with the same part of a filename

I have a directory with thousands of TIFF files. An example of the files are:

32202900_55967.tif
32202900_56130.tif
32206130_57427.tif
32206130_57515.tif
32209667_60298.tif
32209667_60508.tif
and so on...

As you can see, the first 8 digits of some of the filenames are exactly the same. These actually belong together as one file. I need a script that joins 2 (or more) TIFF files together which have the same first 8 digits AND removing the underscore and everything after it. So based on the above example, the final output should look like this:

32202900.tif
32206130.tif
32209667.tif
and so on...

Thanks in advance.

Can't say. That's how we got them from a vendor. (!)

Give this a try.  It makes several assumptions;

1) the numbers in places 10-14 in the file name determine how the join is made, lower numbers go first
2) all the file names are the same format
3) Simply cat'ing them together in the right order will preserve the tiff file integrity


last_file=""
for i in `ls *.tiff | sort -n`
do
        first8=`echo $i | cut -c1-8`
        filename=`echo $i | cut -c1-8,15-19`
        if [ "$first8" != "$last_file" ]
        then
                echo "New File $filename"
                last_file=$first8
                cat $i > $filename
        else
                cat $i >> $filename
        fi

Didn't work. Saved it as a .bat in the same directory. Ran it. Nothing happens.

Hey. I wasn't sure if you were writing a script for a windows bat file or vbs. Thought I'd check.

Didn't get any response, so got help from different websites. Thought to post the solution here and close the question out.
