How can I add incremental integer row in a text file using grep or awk command in linux terminal?












0















I have a text file which contains 10 million+ lines. The file looks like as bellow:



1902400023
1902400029
1902400031
1902400032


I wanted to add a heading, incremental ID number and a constant SHORTCODE.
Expecting Result:



ID,MSISDN,SHORTCODE
1,1902400023,1
2,1902400029,1
3,1902400031,1
4,1902400032,1


And this will continue to till the end of file and write in another file.
