Using cat:
cat file1 file2 file3 >combined-file
cat (short for "concatenate") will read each file given on the command line and concatenate them on its output. You may redirect the concatenated output to a new file, as shown above.
This may also be done in steps (not commonly done, but it shows how to append contents from one file to another):
cat file1 >combined-file
cat file2 >>combined-file
cat file3 >>combined-file
The first command will create or truncate (empty) the file combined-file, while the last two commands will append to that file (>> vs. >).
To select only a few lines from one file and append these to another already existing file:
grep 'PATTERN' file1 >>file2
This would extract all lines from file1 that matched the regular expression PATTERN and append them to the end of file2.
