split a gzip file based on size and have a prefix without changing extension


I have a gzip file

ABC_000023232.gzip
BCD_023232032.gzip

I want to split these files into smaller files but keep the extension same because I am using this as a variable in a script

Code:
for i in `ls *.gzip`
split -b 500K $i $i
done
This produces
Code:
ABC_000023232.gzipaa
ABC_000023232.gzipab
ABC_000023232.gzipac
BCD_023232032.gzipaa
BCD_023232032.gzipac
I want
Code:
ABC_000023232aa.gzip
ABC_000023232ab.gzip
ABC_000023232ac.gzip
BCD_023232032aa.gzip
BCD_023232032ab.gzip

Code:
wanted=`echo $i|cut -d'p' -f2`
fname=`echo $i|cut -d'.' -f1`
new=${fname}${wanted}.gzip

Yep; that code generates the new name for each file as it goes, then add a mv cmd.
Try it on one or two file (backup copies) to see how it works.
