Question

I do have a problem that is too difficult for me, but believe it can be solved very easily in awk.
My data looks like this:

8377885 8384365 8385357 8385877 @ 8378246 8384786 8385450 8386102
66999065 66999928 67091529 @ 66999090 67000051 67091593

It’s different lines that that have ‘@’ exactly in the middle of them. I want to:
1.Combine line elements separated with ‘@’ from first to last;
2.Print all combined elements as column.
Preferred output would look like this:

8377885 8378246
8384365 8384786
8385357 8385450
8385877 8386102
8390268 8390996
66999065 66999090
66999928 67000051
67091529 67091593

Hope someone could help me with this.

Answer 1

below will work:

awk -F"@" '{n=split($1,a," ");split($2,b," ");for(i=1;i<=n;i++)print a[i],b[i]}' your_file

tested below:

> awk -F"@" '{n=split($1,a," ");split($2,b," ");for(i=1;i<=n;i++)print a[i],b[i]}' temp
8377885 8378246
8384365 8384786
8385357 8385450
8385877 8386102
66999065 66999090
66999928 67000051
67091529 67091593
