Print multiple columns in scientific notation

Hi everybody,

I have file 1 with 15 columns, I want to change the formatting of the numbers of columns 10,11 and 12 in the scientific notation.
I used the Following script:

Code:
awk '{print $10}' file1.dat | awk '{printf "%.2e\n", $1}' > file2.dat
awk '{print $11}' file1.dat | awk '{printf "%.2e\n", $1}' > file3.dat
awk '{print $12}' file1.dat | awk '{printf "%.2e\n", $1}' > file4.dat

I have two questions:

a)How to make changes simultaneously and get these three columns printed in one file? I tried this, but only the column 10 was printed:

Code:
awk '{print $10, $11, $12 }' file1.dat | awk '{printf "%.2e\n", $1, $2, $3 }' > file5.dat

b) Is it possible to get the formatting conversion of columns 10,11,12 directly in file1.dat, without having to generate extra files?

Thank you!

NAME
gsl-randist - generate random samples from various distributions SYNOPSYS
gsl-randist seed n DIST param1 param2 [..] DESCRIPTION
gsl-randist is a demonstration program for the GNU Scientific Library. It generates n random samples from the distribution DIST using the distribution parameters param1, param2, ... EXAMPLE
Here is an example. We generate 10000 random samples from a Cauchy distribution with a width of 30 and histogram them over the range -100 to 100, using 200 bins. gsl-randist 0 10000 cauchy 30 | gsl-histogram -100 100 200 > histogram.dat A plot of the resulting histogram will show the familiar shape of the Cauchy distribution with fluctuations caused by the finite sample size. awk '{print $1, $3 ; print $2, $3}' histogram.dat | graph -T X SEE ALSO
