4 atool is a script for managing file archives of various types (tar,
7 The main command is aunpack which extracts files from an archive. Did you
8 ever extract files from an archive, not checking whether the files were
9 located in a subdirectory or in the top directory of the archive, resulting
10 in files scattered all over the place? aunpack overcomes this problem by
11 first extracting to a new directory. If there was only a single file in the
12 archive, that file is moved to the original directory. aunpack also
13 prevents local files from being overwritten by mistake.
15 The other commands provided are apack (to create archives), als (to list
16 files in archives), and acat (to extract files to standard out). As atool
17 invokes external programs to handle the archives, not all commands may be
18 supported for a certain type of archives.
20 atool identifies archives by their file extension. Sometimes this is not
21 possible - for instance rar archives usually have varying numeric file
22 extensions. In those cases when atool can't identify the format, file is
23 used instead. (atool can be configured not to use file.)
