Split a record

UNIX Scripting
Hi I am trying to read a record and split it into multiple records
My Record looks like this

UniqueID is 1001
segments are A,B,C,D
length of each segment is 4 characters after the segment 0010 for A
0010 for B 0012 for C etc

I have to split this file into

and Then I will be appending the Unique ID to the other segments like

Can anyone help me how to read a line and cut it and write it out
I wanna loop the line until end of line

Can anyone guide me how to do this

This is one way to do it...
I'm sure someone will have a shorter code than this.

while read record
  uniq_id=`echo $record | awk -F'A' '{print $1}'`
  part1=`echo $record | awk -F'B' '{print $1}'`
  part2=`echo $record | awk -F'C' '{print $1}' | awk -F'B' '{print "B" $2}'`
  part3=`echo $record | awk -F'D' '{print $1}' | awk -F'C' '{print "C" $2}'`
  part4=`echo $record | awk -F'D' '{print "D" $2}'`
  echo $part1
  echo $uniq_id$part2
  echo $uniq_id$part3
  echo $uniq_id$part4
  echo "******************************************"
done < test1.txt

In perl you could do something like

$str = "1001A0010@B0010*&^0)C0012hgdj&6sD0020fhfri93kivmepi9";

$str =~ /(.*)A(.*)B(.*)C(.*)D(.*)/;

$uni = $1;
$a = $2;
$b = $3;
$c = $4;
$d = $5;

$seg1 = $uni.A.$a;
$seg2 = $uni.B.$b;
$seg3 = $uni.C.$c;
$seg4 = $uni.D.$d;

and so on.

No I cannot split the record based on the A. I have to look at the Segement A and then increase it by length then find next Segment (It can be any B,C,D,E,F) then split it until end of line

I have to loop the line until end of line and split the line based on length
The segments are variable ....

Is this a school project ? Smilie

If the length of the Segment is fixed -> 4 characters, than why do you need to have the rest of the junk in the output

echo "1001A0010@B0010*&^0)C0012hgdj&6sD0020fhfri93kivmepi9" |
awk '{
    for(i=2;i<=n;++i) {
       if (cnt)
