I would like to match the line counts of multiple text files to the same line count as a target file.

For example, File A has 1000 lines. This is the target line count.

Multiple files B, C, D, and E etc. are imported to batch runner. They all have different line counts: 1347, 1894, 2004 etc.

I would like to sequentially delete random lines from the source files and output new B,C, D, and E text files all with 1000 lines.

Sequential deletion of random lines means that the order of the output l
Input Sample:
For example:

Original File B:

Line 1
Line 2
Line 3
Line 4
Line 5
etc.  total of 1347 lines

Original File C:

Line 1
Line 2
Line 3
Line 4
Line 5
etc.  total of 1894 lines
Output Sample:
Output File B:

Line 2
Line 3
Line 5
etc.  until 1000 lines reached

Output File C:

Line 1
Line 2
Line 4
etc.  until 1000 lines reached

Script 964 does something similar by entering a value for the number of lines to be extracted but the output file lines are in random order instead of sequential.
Hint: You need to Download and install "Replace Pioneer" on windows platform to finish following steps.
1. open Tools->Batch Runner menu
2. drag multiple files to "batch runner" window.
