Awk to add columns from a file into an existing file

Shell Programming and Scripting

Hi!
I would need some help to add the last two columns of one file into another file using awk (or something similar).
For example, I have:

file 1: file 2:

car book day root lag
bar look pay boot tag
tar took may moot sag

I want to have: file 2 transformed into:

file 2 (new):

root lag book day
boot tag look pay
moot sag took may

Thanks!!!

2

man awk with print function.

3

Try:

paste -d" " file_2 <(cut -d" " -f2,3 file_1)
4

cat file1| awk '{print $4,$5,$2,$3}'

5

no need cat.

awk '{print $4,$5,$2,$3}' file1

sed 's/\(.*\) \(.*\) \(.*\) \(.*\) \(.*\)/\4 \5 \2 \3/' file_in
root lag book day
boot tag look pay
moot sag took may

You can use >file_out to write the results back to a file

sed 's/\(.*\) \(.*\) \(.*\) \(.*\) \(.*\)/\4 \5 \2 \3/' file_in >file_out
