-.Dd June 27, 2023
-.Dt UNZIP 1
-.Os
-.Sh NAME
-.Nm unzip
-.Nd extract files from a ZIP archive
-.Sh SYNOPSIS
-.Nm
-.Op Fl aCcfjLlnopqtuvy
-.Op { Fl O | Fl I No } Ar encoding
-.Op Fl d Ar dir
-.Op Fl x Ar pattern
-.Op Fl P Ar password
-.Ar zipfile
-.Op Ar member ...
-.Sh DESCRIPTION
-.\" ...
-The following options are available:
-.Bl -tag -width Fl
-.It Fl a
-When extracting a text file, convert DOS-style line endings to
-Unix-style line endings.
-.It Fl C
-Match file names case-insensitively.
-.It Fl c
-Extract to stdout/screen.
-When extracting files from the zipfile, they are written to stdout.
-This is similar to
-.Fl p ,
-but does not suppress normal output.
-.It Fl d Ar dir
-Extract files into the specified directory rather than the current
-directory.
-.It Fl f
-Update existing.
-Extract only files from the zipfile if a file with the same name
-already exists on disk and is older than the former.
-Otherwise, the file is silently skipped.
-.It Fl I Ar encoding
-.It Fl O Ar encoding
-Convert filenames from the specified encoding.
-.It Fl j
-Ignore directories stored in the zipfile; instead, extract all files
-directly into the extraction directory.
-.It Fl L
-Convert the names of the extracted files and directories to lowercase.
-.It Fl l
-List, rather than extract, the contents of the zipfile.
-.It Fl n
-No overwrite.
-When extracting a file from the zipfile, if a file with the same name
-already exists on disk, the file is silently skipped.
-.It Fl o
-Overwrite.
-When extracting a file from the zipfile, if a file with the same name
-already exists on disk, the existing file is replaced with the file
-from the zipfile.
-.It Fl p
-Extract to stdout.
-When extracting files from the zipfile, they are written to stdout.
-The normal output is suppressed as if
-.Fl q
-was specified.
-.It Fl P Ar password
-Extract encrypted files using a password.
-Putting a password on the command line using this option can be
-insecure.
-.It Fl q
-Quiet: print less information while extracting.
-.It Fl t
-Test: do not extract anything, but verify the checksum of every file
-in the archive.
-.It Fl u
-Update.
-When extracting a file from the zipfile, if a file with the same name
-already exists on disk, the existing file is replaced with the file
-from the zipfile if and only if the latter is newer than the former.
-Otherwise, the file is silently skipped.
-.It Fl v
-List verbosely, rather than extract, the contents of the zipfile.
-This differs from
-.Fl l
-by using the long listing.
-Note that most of the data is currently fake and does not reflect the
-content of the archive.
-.It Fl x Ar pattern
-Exclude files matching the pattern
-.Ar pattern .
-.It Fl y
-Print four digit years in listings instead of two.
-.It Fl Z Ar mode
-Emulate
-.Xr zipinfo 1L
-mode.
-Enabling
-.Xr zipinfo 1L
-mode changes the way in which additional arguments are parsed.
-Currently only
-.Xr zipinfo 1L
-mode 1 is supported, which lists the file names one per line.
-.It Ar [member ...]
-Optional list of members to extract from the zipfile.
-Can include patterns, e.g.,
-.Ar 'memberdir/*'
-will extract all files and dirs below memberdir.
-.El
-.Pp
-Note that only one of
-.Fl n ,
-.Fl o ,
-and
-.Fl u
-may be specified.
-If specified filename is
-.Qq - ,
-then data is read from
-.Va stdin .
-.Sh ENVIRONMENT
-If the
-.Ev UNZIP_DEBUG
-environment variable is defined, the
-.Fl q
-command-line option has no effect, and additional debugging
-information will be printed to
-.Va stderr .
-.Sh COMPATIBILITY
-The
-.Nm
-utility aims to be sufficiently compatible with other implementations
-to serve as a drop-in replacement in the context of the
-.Xr ports 7
-system.
-No attempt has been made to replicate functionality which is not
-required for that purpose.
-.Pp
-For compatibility reasons, command-line options will be recognized if
-they are listed not only before but also after the name of the
-zipfile.
-.Pp
-Normally, the
-.Fl a
-option should only affect files which are marked as text files in the
-zipfile's central directory.
-Since the
-.Xr archive 3
-library does not provide access to that information, it is not available
-to the
-.Nm
-utility.
-Instead, the
-.Nm
-utility will assume that a file is a text file if no non-ASCII
-characters are present within the first block of data decompressed for
-that file.
-If non-ASCII characters appear in subsequent blocks of data, a warning
-will be issued.
-.Pp
-The
-.Nm
-utility is only able to process ZIP archives handled by
-.Xr libarchive 3 .
-Depending on the installed version of
-.Xr libarchive 3 ,
-this may or may not include self-extracting or ZIPX archives.
-.Sh SEE ALSO
-.Xr libarchive 3
-.Sh HISTORY
-The
-.Nm
-utility appeared in
-.Fx 8.0 .
-.Sh AUTHORS
-The
-.Nm
-utility and this manual page were written by
-.An Dag-Erling Sm\(/orgrav Aq Mt des@FreeBSD.org .
-It uses the
-.Xr archive 3
-library developed by
-.An Tim Kientzle Aq Mt kientzle@FreeBSD.org .
