CODE EXAMPLE FOR SHELL

echo "-n"

-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
       1003.1-2001 (``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.
