Assuming you have a input file in.txt with following lines:
a
b
c
and you'd like to concatenate these 3 lines into a single line to a file out.txt i.e.
abc
You can use the following PowerShell command:
-join (cat in.txt) | out-file out.txt
Basically, the cat in.txt
is executed first and returned the content of in.txt as an array of strings. The -join
cmdlet then joins the lines together into a single line, which is then piped (|
) into the out-file
cmdlet to produce the out.txt file.
