The bunset command is used to unset a binary file.
bunset <&binvar> [&binvar &binvar ... &binvar]
This unsets all specified binary files. Unlike unset, bunset doesn't work with wildcards.
Example
bset &test 1 65 66 67 echo -a $bvar(&test,0) returns 3 bunset &test echo -a $bvar(&test,0) returns 0
In this case the first echo will echo "1" as &test is filled with 1 byte, the second echo will echo "0" as &test is unset.
