Data from table to column

UNIX for Advanced & Expert Users

Hi All,
in bash I have a text file which is something like

  7.96634E-07 1.0000   0.00000E+00 0.0000   0.00000E+00 0.0000   1.59327E-06 0.7071
  2.23058E-05 0.1890   6.61207E-05 0.1098   1.13919E-04 0.0865   1.47377E-04 0.0747
....
....
  0.00000E+00 0.0000   0.00000E+00 0.0000   0.00000E+00 0.0000   0.00000E+00 0.0000
  1.01890E-03 0.0291   3.20088E-03 0.0172   5.45217E-03 0.0134   8.06035E-03 0.0111

Is there a way to read sequentially the data an put them in two columns. In the previous case it would be.

  7.96634E-07 1.0000
  0.00000E+00 0.0000
  0.00000E+00 0.0000
  1.59327E-06 0.7071
  2.23058E-05 0.1890
  6.61207E-05 0.1098
  1.13919E-04 0.0865
  1.47377E-04 0.0747
....
....

Thank you,
Sarah

sed 's/[ ]\{3\}/\n/g' input_file

I have the input file with the following contents

7.96634E-07 1.0000   0.00000E+00 0.0000   0.00000E+00 0.0000   1.59327E-06 0.7071
2.23058E-05 0.1890   6.61207E-05 0.1098   1.13919E-04 0.0865   1.47377E-04 0.0747
0.00000E+00 0.0000   0.00000E+00 0.0000   0.00000E+00 0.0000   0.00000E+00 0.0000
1.01890E-03 0.0291   3.20088E-03 0.0172   5.45217E-03 0.0134   8.06035E-03 0.0111

When I am executing the above command I got the output as follows

7.96634E-07 1.0000
0.00000E+00 0.0000
0.00000E+00 0.0000

1.47377E-04 0.0747
0.00000E+00 0.0000
0.00000E+00 0.0000

Try this,

sed -re "s/[ ]{2,}/\n/g" test_file

Thank you, it works fine except that some times I have two \n probably because there is a new line in the original file.
Anyway to overcome this?

It doesn't seems to work. The output is the same as the input. Thank you anyway,

Try this,

sed -re "/^$/d; s/[ ]{2,}/\n/g"  test_file

Try:

xargs -n 2 < infile

The solution if scrutinizer does the job, not yet the one of Nila, but I found a solution. Thank you all,
