Hi! I want to convert the lines 1.1,3.19e-4 1.2,3.05e-3 10.5,9.14e8 (as example)
to
1,1 & $3,19 \cdot 10^{-4}$\ etc.. from one file and save these in a new file Rly lost here except I know I should use regexp and MAYBE sed somehow :) Thx for any help
Assuming that you have those lines in a file called numbers.txt, you can execute the following (all on one line):
cat numbers.txt | tr '.,e' ',^^' | awk -F^ '{printf("%s & $%s \cdot 10^{%s}$\\\n", $1, $2, $3);}'
The output will be:
1,1 & $3,19 \cdot 10^{-4}$\ 1,2 & $3,05 \cdot 10^{-3}$\ 10,5 & $9,14 \cdot 10^{8}$\
Not the most elegant solution, but it works. I hope this is what you were looking for.
