after some post post thinking, i recalled that i did try "ignoreboth",

in addition, here is info from gnu .org:
from the gnu 'bash reference manual';
you will find;
A colon-separated list of values controlling how commands are saved
on the history list. If the list of values includes ‘ignorespace’,
lines which begin with a space character are not saved in the history
list. A value of ‘ignoredups’ causes lines which match the previous
history entry to not be saved. A value of ‘ignoreboth’ is shorthand
for ‘ignorespace’ and ‘ignoredups’. A value of ‘erasedups’ causes
all previous lines matching the current line to be removed from the
history list before that line is saved. Any value not in the above
list is ignored. If HISTCONTROL is unset, or does not include a
valid value, all lines read by the shell parser are saved on the
history list, subject to the value of HISTIGNORE. The second and
subsequent lines of a multi-line compound command are not tested,
and are added to the history regardless of the value of HISTCONTROL.
A colon-separated list of patterns used to decide which command lines
should be saved on the history list. Each pattern is anchored at the
beginning of the line and must match the complete line (no implicit ‘*’
is appended). Each pattern is tested against the line after the checks
specified by HISTCONTROL are applied. In addition to the normal shell
pattern matching characters, ‘&’ matches the previous history line. ‘&’
may be escaped using a backslash; the backslash is removed before
attempting a match. The second and subsequent lines of a multi-line
compound command are not tested, and are added to the history regardless
of the value of HISTIGNORE.
HISTIGNORE subsumes the function of HISTCONTROL. A pattern of ‘&’ is
identical to ignoredups, and a pattern of ‘[ ]*’ is identical to
ignorespace. Combining these two patterns, separating them with a colon,
provides the functionality of ignoreboth.
