I'm not sure i follow.
Input now is also inconsistent, with first two rows having 13 fields and last having 12.
Now you say you require fields 2,4 and 10, but on expected output you changed only field 4 for the first two lines and field 5 for the last line.
I have no idea what to do with 2,10, but we can work with 4 and 5 using awk match and regex.
Will it be a good guess now, or are we missing some input again ?
Be sure other fields in line do not match P<year week regex>, since we are using $0

Hi all,
I'm using Red Hat Linux and want to move some folders and files around but not change the modified date. Is this possible?
I know cp has a -p flag which seems to do what I want, but this is a large volume of data so copying and deleting would not be feasible. (13 Replies)
