Shell Programming and Scripting

hi all,

i have a big problem, and i don´t know what to do.
i have a flat file with several fields, which are separated by ";" like this:

5656838-7B;97030000-7;*;V16106133 ;1;1;
4612062-0B;97030000-7;*;C14038149 ;1;2;
8044938-0B;97030000-7;*;V16034219 ;1;2;

where B is a blank space.

each line is a record, and all have the same length. and each field has its determinated length. Example: field1[10],field2[10],field3[1],
field4[1],field5[8], ...

what i need, is align the content of the field 1 and 2 to the rigth, and put a zero to its left, like this:

05656838-7;97030000-7;*;V16106133 ;1;1;
04612062-0;97030000-7;*;C14038149 ;1;2;
08044938-0;97030000-7;*;V16034219 ;1;2;

is that possible??
please, any idea
thanks

hasn't it already been answered here?

seems very similar to me......

Another way:

cut -c1-9 filename >temp1
cut -c11- filename>temp2
paste -d"\0" temp1 temp2|sed 's/^/0/g'
