 From the man page of echo:

      The following option is available:

      -n    Do not print the trailing newline character.  This may  
also be
            achieved by appending `\c' to the end of the string, as is  
done by
            iBCS2 compatible systems.  Note that this option as well  
as the
            effect of `\c' are implementation-defined in IEEE Std  
            (``POSIX.1'') as amended by Cor. 1-2002.  Applications  
aiming for
            maximum portability are strongly encouraged to use  
printf(1) to
            suppress the newline character.

      Some shells may provide a builtin echo command which is similar  
or iden-
      tical to this utility.  Most notably, the builtin echo in sh(1)  
does not
      accept the -n option.  Consult the builtin(1) manual page.
