AWK
I have a file that has 5 cloumns. I want to write a script that would read each line (row), go to columns 3 (1er) and 5 (ens); whenever there is a match between the two columns i.e their values, the script with output the corresponding value in colums 1 and 2. If someone could help me, I would truly appreciate it.
For example, in column 1 below, row 9 has value of 65.8 for column 3(1er) and colum 5 (ens); In essence the script would have to let me know of these occurences.

Thanks!

Here is the file:

Code:
Caul	Preface	1er	2eme	ens
8	1	32.6	5.7	38.3

Lets say your file name is test.txt
then

Code:
awk 'BEGIN { FS="\t"} {if($3==$5) print $1,$2;}' test.txt

Thank you for the reply. What if I had only the first four columns and wanted to add a fifth column (i.e. ens in output file). Note that the 5th column is the sum of column 3 and column 4. How would I write a program that inserts a fifth column which is the sum of the columns 3 and 4?
input_file
Code:
Caul	Preface	1er	2eme	
8	1	32.6	5.7	
8	2	17.7	1.3	
8	3	34.8	8.2	
9	1	65.8	0	
9	2	46.1	10.7	
9	3	12	2.9	
10	1	17	5	
10	2	36.9	0	
10	3	4.6	1.1

output
Code:
Caul	Preface	1er	2eme	ens
8	1	32.6	5.7	38.3
8	2	17.7	1.3	19
8	3	34.8	8.2	43
9	1	65.8	0	65.8
9	2	46.1	10.7	56.8
9	3	12	2.9	14.9
10	1	17	5	22
10	2	36.9	0	36.9
10	3	4.6	1.1	5.7

This should work. It assumes that the first record contains a header.

Code:
awk '
        NR == 1 {
                printf( "Caul Preface 1er 2eme ens\n" );        # header
                next;
        }
        { printf( "%s %.1f\n", $0, $3 + $4 ); }
' infile

Thank you guys, I am half way through what I want to accomplish. My script so far is working fine. The only issue I have is that the output file for this script is:
Caul Preface
9 1
10 2
Instead, I want the output file to be:
Caul Preface
9 1
9 2
9 3
10 1
10 2
10 3

I want all references to either Caul 9 or Caul 10 to be displayed. That would be fantastic if I could get it to work this way.
