I am Notepad++ user but I would use free AWK tool for this because it is lean and effective.

AWK solution (just download awk.exe and run the following command line)

awk "BEGIN { c = 20978 } { print $0 c++ }" input.txt > output.txt 

Result:

Downloading:

you do not even need to install the tool, just download and unpack binaries.zip and EXE is located in gawk-3.1.6-1-bin.zip\bin\awk.exe.

What the instructions do:

• BEGIN { c = 20978 } we initialized c to 20978. BEGIN section runs only once.
• section { print $0 c++ } runs once for each line: we print that line (it is stored in $0) and the value of our counter c (which we immediately increase: c++)

Making it reusable:

If you would like to keep the source code for future use, put it to file numbering.awk with some nicer formatting:

BEGIN { c = 20978 } { print $0 c++ } 

And use modified command line referring to that source file:

awk -f numbering.awk input.txt > output.txt 

You can save this command into numbering.bat file so you won't need to rememeber it.

Additional explanation:

For your information, less cryptic form of the source would say:

# this section runs once at the beginning BEGIN { c = 20978 } # initialization of the counter "c" # this section runs once for each line { print $0 c; # print original line followed by value of counter "c" c = c + 1; # assign value of calculation "c + 1" into "c" } 

1. Add some spaces to the last time so that the line becomes the longest.

   

2. Hold Alt+Shift then hit Up Arrows to select an area up to the top of the text.

   

3. Keep holding Alt+Shift then hit Right Arrows to adjust the area so that the cursors are at the end of the lines.

   

4. Hit Alt+C to invoke the Column Editor to add sequence numbers.

   

   

5. Hit Ctrl+H to replace the regular expression \ +([0-9]+)$ with $1

   

   

   Done!
