Replace other instances except the first one
Hi Friends,

This is my input

Code:
track type=alpha name="omega"
fixedStep chrom=chr10 name="omega"
1

track type=alpha name="omega"
fixedStep chrom=chr11 name="omega"

track type=alpha name="omega"
fixedStep chrom=chr12 name="omega"
1212123
5456
8789

Now, my output should be

Code:
track type=alpha name="omega"
fixedStep chrom=chr10 name="omega"
1

fixedStep chrom=chr12 name="omega"
1212123
5456
8789
4554

Basically, leave the first
Quote:
track type=
section. But, replace all other instances of it.

Any thoughts are highly appreciated.

A small hint is that each next line after the
Quote:
track type=
line starts with
Quote:
fixed
.

Thanks in advance
