bsasasasasa=2

abc=214

your command gives the correct ouput.

Code:
 
bash-3.00$ sed 's/.*=//' test
1

214

itkamaraj, could you explain, what is that mean? I really want to know about regex.

* (star)Repeats the previous item zero or more times. Greedy, so as many items as possible will be matched before trying permutations with less matches of the preceding item, up to the point where the preceding item is not matched at all
Regular Expressions Reference - Basic Syntax

.*= this will match the aasaasas=, bsasasasasa=, ..........

so i am replacing that with empty sed 's/.*=//'
