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.

Please excuse me for my messy equation. As I am relatively new to Mathematics Stack Exchange, I do not know how to insert superscripts.

                    0 I just flashed my vocore2u with openwrt 18.06.1, and plug it with an ethernet cable to access network while setting up wireless access-point for my phone. The AP is working and connected to the network, but the ip in my phone is in the subnet of another router. And there's no ip assigned to my vocore2 so I cannot ssh into it. After connecting to vocore2 with serial terminal, ping 8.8.8.8 is also failed. How can I make my vocore2 gain ip from the router and setting up the network well? root@OpenWrt:/etc/config# ifconfig apcli0 Link encap:Ethernet HWaddr BA:D8:12:07:01:71 inet6 addr: fe80::b8d8:12ff:fe07:171/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 erro
