Connect it to a command tr

that will remove newlines:

cat file1 file2 | tr -d "\n" > file3

What about

$ echo $(cat aaa)$(cat bbb)
aaabbb

Pearl for the rescue:

perl -pechomp file1 file2 file3... > file.out

See chomp .

This should work:

printf "%s%s\n" "$(<file1)" "$(<file2)" >file3

Or:

echo "$(<file1)$(<file2)" >file3
