Hi guys,

I need help in extracting one column of numbers from two different files and display it in a output file. In specific, I want to extrac the column no.2 ($2) from each file, file1.txt, file2.txt. Then place both extracted columns in a one file, out.txt.

the line command I use to call the AWK code and the files is this:
awk -f code.awk file1.txt file2.txt > out.txt

code.awk I have is (and is worng! ):
#Extracting columns
#
BEGIN {}
#{print $2 < file1.txt , $2<file2.txt}
END {}

I appreciate a lot your kind help,

cut and paste normally work on tab-delimited input; if you have variable amounts of spaces as separators, awk is definitely the way to go.

Pure awk:

side by side:
concatenated on one column:

hi Shamrock,

the output should be the column#2 of file 1, Tab, the column #2 of file 2

file1
1 2
2 3
3 4

file2
5 8
6 9
7 10

output
2 8
3 9
4 10
