Writing a text to many files

Is there a command in shell-script that I can use that copies a string or writes it to many files? Say I have files a, b and c and I want to copy or write the text "Hallo, I am a newbie!" to all these files? I know I can do echo "Hallo, I am a newbie!" > a but this only copies it to one file. How can I do it to copy to all without repeating this command again and again.

Thanks in advance.

NAME
cp - copy SYNOPSIS
cp [ -ip ] file1 file2 cp [ -ipr ] file ... directory DESCRIPTION
File1 is copied onto file2. By default, the mode and owner of file2 are preserved if it already existed; otherwise the mode of the source file modified by the current umask(2) is used. The -p option causes cp to attempt to preserve (duplicate) in its copies the modification times and modes of the source files, ignoring the present umask. In the second form, one or more files are copied into the directory with their original file-names. Cp refuses to copy a file onto itself. If the -i option is specified, cp will prompt the user with the name of the file whenever the copy will cause an old file to be overwrit- ten. An answer of 'y' will cause cp to continue. Any other answer will prevent it from overwriting the file. If the -r option is specified and any of the source files are directories, cp copies each subtree rooted at that name; in this case the destination must be a directory. SEE ALSO
