Combine two text files with powershell

Question

I have two text files with data.

First text file contains a big list of fullpaths to my files. d:\cat\cat1.txt

d:\test\file1-1.txt
d:\test\file1-2.txt
....
d:\test\file1-N.txt

Second text file contains a short list of fullpath to my \files

d:\cat\file\cat2.txt

d:\test\file2-1.txt
d:\test\file2-2.txt

I need third file which contains

d:\test\file1-1.txt
d:\test\file1-2.txt
d:\test\file2-1.txt
d:\test\file1-3.txt
d:\test\file1-4.txt
d:\test\file2-2.txt
d:\test\file1-5.txt
d:\test\file1-6.txt
d:\test\file2-1.txt

Thx for help.

Your going to need to explain the rule for sorting the output. We can only guess. — zdan, Apr 15 '12 at 16:39

If you want to combine multiple files ( 2 or more ), you can do:

gc d:\cat\cat1.txt,d:\cat\file\cat2.txt | out-file d:\cat\combinedcat.txt

It is not clear from your example what kind of "specific" combination you want, so you may want to explain that, but the logic for combining files will be like above.

If you want to combine all text files in a path, try: gc C:\Path\*.txt | Out-file C:\Path\MergedTextFile.txt – The Woo Aug 11 '14 at 04:38

Get the content of both files and save output to a new file:

Get-ChildItem d:\cat\cat1.txt,d:\cat\file\cat2.txt | 
  Get-Content | Out-File d:\cat\cat3.txt

Why is it - when I have only 3 short files and I replace Get-ChildItem with Get-ChildItem -Recurse -Filter *.txt it actually adds those file in an endless loop? – Maurice Klimek Nov 18 '16 at 20:37
