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.

Examples

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 3 as &test is filled with 3 bytes, the second echo will echo 0 as &test is unset.

bset &test 1 65 66 67
bset &another 1 97 98
echo -a $bvar(&test,0) returns 3
echo -a $bvar(&another,0) returns 2
bunset &test &another
echo -a $bvar(&test,0) returns 0
echo -a $bvar(&another,0) returns 0

This is an example of two binary files being unset with one command.
