cut awk sed and others are not SHELL commands. One way could be with bash: string one two three tab ($string)$ echo ${tab[0]}one$ echo ${tab[1]}two$ echo ${tab[2]}threehttp://www.big-up.org

Hi The answer is excellent but I like to modify it a little only the command
string one two three tab ($string)$ echo ${tab[0]}one ${tab[1]}two ${tab[2]}three it self is enough to ptint one two three no more echos' are required.
