Extended Help for UnZip
See the UnZip Manual for more detailed help
UnZip lists and extracts files in zip archives. The default action is to
extract zipfile entries to the current directory, creating directories as
needed. With appropriate options, UnZip lists the contents of archives
instead.
Basic unzip command line:
unzip [-Z] options archive[.zip] [file ...] [-x xfile ...] [-d exdir]
Some examples:
unzip -l foo.zip - list files in short format in archive foo.zip
unzip -t foo - test the files in archive foo
...
e se você estiver descompactando um arquivo, -h faz isso:
-h Linha do cabeçalho da lista. Inclui nome do arquivo, tamanho real e total de arquivos.
