i am getting the error like "-: more tokens expected"

Thanks in Advance
The most likely problem is that $k or $kkm expands to an empty string.
Code:
if [[ "$k" -le "$kkm" ]] && [[ ${k:-0} -ne 0 ]]; then

will probably get rid of that error message, but may give you a different error when it finds that one or both of the arguments to the -le operator are not numeric strings. It looks like your second test assumes that $k might be an empty string and adjusts for that fact; the first test does not. Maybe you wanted:
Code:
if [[ ${k:=0} -le ${kkm:=0} ]] && [[ $k -ne 0 ]]; then

which will set k and kkm, respectively, to 0 if they were originally unset or were set to empty strings. Note that this still won't protect you if $k or $kkm expands to a non-empty, non-numeric string.
