Hi Unix gurus,
I have a file. I need to insert sequential number at the starting of the file. Fields are delimited by "|". I know the starting number.


Example:

File is as follows

|123|4test|test
|121|2test|test
|x12|1test|test
|vd123|5test|test

starting number is : 120

output must be :

120|123|4test|test
121|121|2test|test
122|x12|1test|test
123|vd123|5test|test


Advance thanks for helping.
