Rename file last char
I want to rename the file from below format to

ABCDEFCGHF20090112345623.DAT to

ABCDEFCGHF20090112345624.DAT

the last digit before dot to increment to 1. if it 9 should become 0

How to do this in simple way?

One way, try it first without the coloured part (not tested):

Code:
ls ABC*.DAT |
awk -F"." '{s=substr($1,length($1))
s++;s=s==10?0:s
printf("mv %s %s%s.%s\n", $0, substr($1,1,length($1)-1), s, $2)}
' | sh

Regards

Code:
file=ABCDEFCGHF20090112345623.DAT
base=${file%.*}         # => ABCDEFCGHF20090112345623
suffix=${file#"$base"}  # => .DAT
prefix=${base%%[0-9]*}  # => ABCDEFCGHF
num=${base#"$prefix"}   # -> 20090112345623
newfile=$prefix$(( $num + 1 ))$suffix # => ABCDEFCGHF20090112345624.DAT
