No, it should be 21:

% echo -n 'A'|expand -t4|wc -c
   1

% echo -n '\t\t\tHello\tW'|expand -t4|wc -c
  21

Please forgive me, but my opinion this is wrong!!!

Example: (a TAB is XXXX := Tab Size=4)

\t\t\tHello\tW written as an array beginning at index 1:

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 X X X X X X X X X X X X H e l l o X X X X W | | | | | | | | | | | ---TAB---- ---TAB---- ---TAB---- --Hello------ ---TAB---- W

If % echo -en '\t\t\tHello\tW'|expand -t4|wc -c is right then the 4th TAB is count only as 3 spaces plus \t !

Cheers,
