I need to concatenate some relatively large text files, and would prefer to do this via the command line. Unfortunately I only have Windows, and cannot install new software.
This takes Test.txt with headers and appends Test1.txt and Test2.txt and writes results to Testresult.txt file after stripping headers from second and third files respectively:
type C:\Test.txt > C:\Testresult.txt && more +1 C:\Test1.txt >> C:\Testresult.txt && more +1 C:\Test2.txt >> C:\Testresult.txt
