Cut file name into two parts in unix

Question

I have a requirement to cut a file name into two parts.
So my file name is : 'SIC_ETL_MAIN_0.1.zip'
I want to cut the file name into parts and load into two variable separately Expected Output:

SIC_ETL_MAIN - var1
0.1 - var2

Answer 1

using grep

$echo SIC_ETL_MAIN_0.1.zip |  grep -o '[A-Z_]*[A-Z]'
SIC_ETL_MAIN
$echo SIC_ETL_MAIN_0.1.zip |  grep -o '[0-9\.]*[0-9]'
0.1
$

Edit: Variable assignment

$var1=$(echo SIC_ETL_MAIN_0.1.zip |  grep -o '[A-Z_]*[A-Z]')
$var2=$(echo SIC_ETL_MAIN_0.1.zip |  grep -o '[0-9\.]*[0-9]')
$echo "Var1=${var1}  Var2=${var2}"                                                
Var1=SIC_ETL_MAIN  Var2=0.1
