See the man page excerpt below for details, these examples are done with

$ uname -a
SunOS alvin 5.7 Generic sun4u sparc SUNW,Ultra-5_10
$ echo ""

$ echo -n ""
$ /bin/echo ""

$ /bin/echo -n ""
$ echo '\c'
$ /bin/echo '\c'

Excerpts from 'echo(1)':

     The C shell, the Korn shell, and the Bourne shell  all  have
     echo   built-in commands, which, by default, will be invoked
     if the user  calls  echo   without  a  full  pathname.   See
     shell_builtins(1).   sh   's  echo  ,  ksh  's  echo  ,  and
     /usr/bin/echo understand the back-slashed escape characters,
     except  that sh 's echo  does not understand \a as the alert
     character. In addition, ksh 's echo , does  not  have  a  -n
     option. sh 's
      echo  and /usr/bin/echo only have a -n option if the  SYSV3
     environment  variable is set (see ENVIRONMENT below).  If it
     is, none of the backslashed characters mentioned  above  are
     availible.  csh  's  echo   and  /usr/ucb/echo, on the other
     hand, have a -n option, but  do  not  understand  the  back-
     slashed escape characters.


     string    A string to be written to standard output.  If any
               operand  is  "-n", it will be treated as a string,
               not an option.  The following character  sequences
               will be recognized within any of the arguments:

               \c        print line without new-line

     Portable applications should not use -n (as the first  argu-
     ment) or escape sequences.


     New applications are encouraged to use  printf   instead  of
     echo .
