UNZOO(1)UNZOO(1)NAMEunzoo - zoo archive extractor
SYNOPSISunzoo
unzoo [-l] [-v] <archive>[.zoo] [<file>..]
unzoo-x [-abnpo] [-j <prefix>] <archive>[.zoo] [<file>..]
DESCRIPTION
This manual page documents briefly the unzoo command. This manual page
was written for the Debian distribution because the original program
does not have a manual page.
unzoo is a program that lists or extracts the members of a zoo archive.
A zoo archive is a file that contains several files, called its mem‐
bers, usually in compressed form to save space. unzoo can list all or
selected members or extract all or selected members, i.e., uncompress
them and write them to files. It cannot add new members or delete mem‐
bers. For this you need the zoo archiver, called zoo, written by Rahul
Dhesi.
If you call unzoo with no arguments, it will first print a summary of
the commands and then prompt for command lines interactively, until you
enter an empty line.
Usually unzoo will only list or extract the latest generation of each
member. But if you append ';<nr>' to a path name pattern the generation
with the number <nr> is listed or extracted. <nr> itself can contain
the wildcard characters '?' and '*', so appending ';*' to a path name
pattern causes all generations to be listed or extracted.
OPTIONS
A summary of options is included below.
-l list the members in the archive <archive>. For each member unzoo
prints the size that the extracted file would have, the compres‐
sion factor, the size that the member occupies in the archive
(not counting the space needed to store the attributes such as
the path name of the file), the date and time when the files
were last modified, and finally the path name itself. Finally
unzoo prints a grand total for the file sizes, the compression
factor, and the member sizes.
<file> list only files matching at least one pattern, '?' matches any
char, '*' matches any string.
-v list also the generation numbers and the comments, where higher
numbers mean later generations. Members for which generations
are disabled are listed with ';0'.
-x extract the members from the archive <archive>. Members are
stored with a full path name in the archive and if the operating
system supports this, they will be extracted into appropriate
subdirectories, which will be created on demand.
-a extract all members as text files (not only those with !TEXT!
comments)
-b extract all members as binary files (even those with !TEXT! com‐
ments)
-n extract no members, only test the integrity. For each member the
name is printed followed by '-- tested' if the member is intact
or by '-- error, CRC failed' if it is not.
-p extract to stdout
-o extract over existing files without asking for confirmation. The
default is to ask for confirmation. unzoo will never overwrite
existing read-only files.
-j prepend the string <prefix> to all path names for the members
before they are extracted. So for example if an archive contains
absolute path names under UNIX, '-j ./' can be used to convert
them to relative pathnames. Note that the directory <prefix>
must exist, unzoo will not create it on demand.
