lead_token

Words and tokens16

Objective

Write a program that receives a single string argument and prints its first whitespace-delimited token, followed by a newline.

Steps

The program must accept exactly one argument. Any other argument count produces wrong number of arguments followed by a newline.
A token is a maximal sequence of non-whitespace characters. Spaces and tabs are both valid delimiters.
Skip any leading whitespace before the first token.
If the argument contains no token at all, print only a newline.

examples

$ ./lead_token "ship it before standup" | cat -e

ship$

$ ./lead_token " typescript ate my tabs" | cat -e

typescript$

$ ./lead_token " " | cat -e

$ ./lead_token "no-space" | cat -e

no-space$
