When the -w option is specified, BRU will wait before attempting to extract a file. For each file, it will do the following:
Print the file name, show the action it is about to take, ask for confirmation. BRU also provides a special response that lets you change your mind. If you type a g (for “go ahead”) instead of y or n, BRU will stop asking for confirmation. The following example shows how this response is used:
$ bru -xvw -f tape0
x ./: please confirm [y/n/g] y
x 2k of 4k [1] ./
x ./bin: please confirm [y/n/g] y
x 2k of 6k [1] ./bin
x ./bin/acctcom: please confirm [y/n/g] y
x 72k of 78k [1] ./bin/acctcom
x ./bin/adb: please confirm [y/n/g] y
x 68k of 146k [1] ./bin/adb
x ./bin/ar: please confirm [y/n/g] g
x 36k of 182k [1] ./bin/ar
x 120k of 302k [1] ./bin/as
x 16k of 318k [1] ./bin/asa
x 4k of 322k [1] ./bin/basename
