Then let me help you think it out:
Given a text file with this data:
1.1,3.19e-4
1.2,3.05e-3
10.5,9.14e-8 <- I'm guessing this was suppose to be scientific not
Convert to a text file:
1,1 & $3,19 \cdot 10^{-4}$\\
1,2 & $3,05 \cdot 10^{-3}$\\
10,5 & $9,14 \cdot 10^{-8}$\\
Look for the pattern match ups:
1.1,3.19e-4
1,1 & $3,19 \cdot 10^{-4}$\\
1.2,3.05e-3
1,2 & $3,05 \cdot 10^{-3}$\\
10.5,9.14e-8
10,5 & $9,14 \cdot 10^{-8}$\\
It looks like:
1) decimals converted to commas
2) commas converted to " & "
3) "e" converted to " \cdot 10^{<>}$\\"
4) <> substituted for whatever comes after the "e"
Now if you convert decimals to commas BEFORE you convert
commas to " & " then you will have garbage, so you need
to convert commas to " & " first, then decimals to
commas, then apply the conversion w/ substituion.
Substitution is handled with the \(\) operator like such:
echo "this is a test" | sed -e 's/\(.*\) is a \(.*\)/\2 is NOT a \1/'
Will output: "test is NOT a this"
Can be done in 3 steps, sed can take multiple operations
if you separate them with ;
