Full Discussion: Copy a column to another column in UNIX fixedwidth file

Not sure if all systems / awk versions will support that large numbers which might be well beyond LINE_MAX (check with getconf LINE_MAX -> 2048). I didn't test this one with looong lines, you may try yourself:
Code:
$ awk '{for (i=to;i<to+4;i++)$i=$(i-back)}1' to=30 back=10 FS="" OFS="" file

It replaces 4 chars at the "to" location with the chars "back" earlier... In your request, "to" would be 1127, and "back" were -551 ... you may want to play around with the signs and operators...
