How can I combine several files into one?

Question

How can I collect several files into a single file?

I tried GZip, but could only get it to create separate files.

It does not have to be compressed.

Answer 1

Simply use cat:

cat file1 file2 file3 > output

If you want to combine all files in the current directory:

cat * > output

If you need to adjust the order of the files in the output, use echo first to get all filenames:

echo *

Then supply them in the desired order to cat.
