Question

I have a file, its content is something like this

#Time value
2.5e-5 1.3
5e-5 2.7
7.5e-5 1.1
0.0001 5.9
0.000125 5.8
0.00015 3
......

How can I replace the line that is with letter e in it (the scientific notation), so that the final file would be

#Time value
0.000025 1.3
0.00005 2.7
0.000075 1.1
0.0001 5.9
0.000125 5.8
0.00015 3
...... 

Is shell script able to do this?

for (any word that is using scientific notation)
{
    replace this word with decimal notation
}

Answer 1

With awk:

$ awk '$1~/e/{printf "%f %s\n", $1,$2}$1~!/e/{print}' file
0.000025 1.3
0.000050 2.7
0.000075 1.1
0.0001 5.9
0.000125 5.8
0.00015 3
