Need some help removing a character from name

Shell Programming and Scripting

I have a file like this:

DDD_ABCDE2AB2_1104081408.104480

I need to remove the 1 after the . in the file name so that it reads:

DDD_ABCDE2AB2_1104081408.04480

Having some difficulty getting the command to work. I tried using

cut -d 26

but that just doesn't work.

Hi.

You have a file, or a filename like that?

# X=DDD_ABCDE2AB2_1104081408.104480              
# echo ${X/.[^.]/.}
DDD_ABCDE2AB2_1104081408.04480

That's an interesting piece of code. I got it to work by doing this:

First grab a list of all the files, then:

while read line
    do drop1=`echo $line | cut -c -25,27-` 
      mv $line $drop1
    done < files.list

It works.

# a=DDD_ABCDE2AB2_1104081408.104480
# a=${a%.*}.${a##*.?}
# echo $a
DDD_ABCDE2AB2_1104081408.04480

same

# a=DDD_ABCDE2AB2_1104081408.104480 
# echo ${a%.*}.${a##*.?}
DDD_ABCDE2AB2_1104081408.04480
