- unix/zipgrep - add additional information to top. Clean up some lines and
add commments. Added code to handle backslashes in archive file names,
and shell-special characters in the pattern. Changed to use "sed" for all
escaping of shell-special characters. Tried to get the exit status to
follow the status of egrep in the complex (default) situation, using only
standard Bourne shell features, and to exit early if egrep returns
status 2 (error). [SMS]
- vms/unzip_cli.help - VMS help updates. [SMS]
- vms/unzip_def.rnh - synchronized option description with unzip_cli.help.
[Chr. Spieler]
- fileio.c: extend backup number range from 65535 to 99999 on 32-bit systems;
fixed limit detection on 16-bit systems. [Chr. Spieler]
- zipinfo.c: changed date layout of "short" (one-line) zipinfo modes to always
use ISO-style YMD order. [Chr. Spieler]
- unix/configure: added a simple compiler test to check for a working C
compiler setup. [Steven M. Schweda]
- cmsmvs/vmmvs.h: removed __EBCDIC preprocessor symbol definition (not used
anywhere in UnZip, breaks compilation on Z-OS). ["Lutz", Chr. Spieler]
- unix/makefile - moved -L link option earlier in unzip$E rule. [Lutz]
- unzip.c - Remove "s" from "permits" in SYMLINKS feature message. [SMS]
- vms/vms.c: simplified the scheme to escape non-last dots, for compatibility

- On VMS (only 8.x or better), support symbolic link creation.
- On VMS, support option to create converted text files in Stream_LF format.
- New -D option to suppress restoration of timestamps for extracted
directory entries (on those ports that support setting of directory
timestamps). By specifying "-DD", this new option also allows to suppress
timestamp restoration for ALL extracted files on all UnZip ports which
support restoration of timestamps.
On VMS, the default behaviour is now to skip restoration of directory
timestamps; here, "--D" restores ALL timestamps, "-D" restores none.
- On OS/2, Win32, and Unix, the (previously optional) feature UNIXBACKUP
to allow saving backup copies of overwritten files on extraction is now
enabled by default.
For the UnZip 6.0 release, we want to give special credit to Myles Bennet,
who started the job of supporting ZIP64 extensions and Large-File (> 2GiB)
and provided a first (alpha-state) port.
The 5.52 maintenance release fixes a few minor problems found in the 5.51
release, closes some more security holes, adds a new AtheOS port, and
contains a Win32 extra-field code cleanup that was not finished earlier.
The most important changes are:

dash. Note that this constitutes a security risk on many systems; cur-
rently running processes are often visible via simple commands (e.g.,
ps(1) under Unix), and command-line histories can be read. If the
first entry of the zip file is encrypted and no password is specified
on the command line, then the user is prompted for a password and the
password is not echoed on the console.
Given the limitation on single-member extraction, funzip is most useful
in conjunction with a secondary archiver program such as tar(1). The
following section includes an example illustrating this usage in the
case of disk backups to tape.
EXAMPLES
To use funzip to extract the first member file of the archive test.zip
and to pipe it into more(1):
funzip test.zip | more
To use funzip to test the first member file of test.zip (any errors
will be reported on standard error):
funzip test.zip > /dev/null
To use zip and funzip in place of compress(1) and zcat(1) (or gzip(1L)
and gzcat(1L)) for tape backups:
tar cf - . | zip -7 | dd of=/dev/nrst0 obs=8k
dd if=/dev/nrst0 ibs=8k | funzip | tar xf -
(where, for example, nrst0 is a SCSI tape drive).
BUGS
When piping an encrypted file into more and allowing funzip to prompt
for password, the terminal may sometimes be reset to a non-echo mode.
This is apparently due to a race condition between the two programs;

[VMS] auto-convert binary files (see \fB\-a\fP above) to fixed-length,
512-byte record format. Doubling the option (\fB\-bb\fP) forces all files
to be extracted in this format. When extracting to standard output
(\fB\-c\fP or \fB\-p\fP option in effect), the default conversion of text
record delimiters is disabled for binary (\fB\-b\fP) resp. all (\fB\-bb\fP)
files.

[when compiled with UNIXBACKUP defined] save a backup copy of each
overwritten file. The backup file is gets the name of the target file with
a tilde and optionally a unique sequence number (up to 5 digits) appended.
The sequence number is applied whenever another file with the original name
plus tilde already exists. When used together with the "overwrite all"
option \fB\-o\fP, numbered backup files are never created. In this case,
all backup files are named as the original file with an appended tilde,
existing backup files are deleted without notice.
This feature works similarly to the default behavior of \fIemacs\fP(1)
in many locations.
.IP
Example: the old copy of ``\fCfoo\fR'' is renamed to ``\fCfoo~\fR''.
.IP
Warning: Users should be aware that the \fB-B\fP option does not prevent
loss of existing data under all circumstances. For example, when
\fIunzip\fP is run in overwrite-all mode, an existing ``\fCfoo~\fR'' file
is deleted before \fIunzip\fP attempts to rename ``\fCfoo\fR'' to
``\fCfoo~\fR''. When this rename attempt fails (because of a file locks,
insufficient privileges, or ...), the extraction of ``\fCfoo~\fR'' gets
cancelled, but the old backup file is already lost. A similar scenario
takes place when the sequence number range for numbered backup files gets
exhausted (99999, or 65535 for 16-bit systems). In this case, the backup
file with the maximum sequence number is deleted and replaced by the new
backup version without notice.

use case-insensitive matching for the selection of archive entries

\fIunzip\fP's philosophy is ``you get what you ask for'' (this is
also responsible for the \fB\-L\fP/\fB\-U\fP change; see the relevant
options below). Because some file systems are fully case-sensitive
(notably those under the Unix operating system) and because
both ZIP archives and \fIunzip\fP itself are portable across platforms,
\fIunzip\fP's default behavior is to match both wildcard and literal

"unzip -t" will test the integrity of stored security descriptors when
present and the operating system is Windows NT.
ZipInfo (unzip -Z) will display information on stored security descriptor
when "unzip -Zv" is specifed.
Potential uses
==============
The obvious use for this new support is to better support backup and restore
operations in a Windows NT environment where NTFS file security is utilized.
This allows individuals and organizations to archive files in a portable
fashion and transport these files across the organization.
Another potential use of this support is setup and installation. This
allows for distribution of Windows NT based applications that have preset
security on files and directories. For example, prior to creation of the
.zip file, the user can set file security via File Manager or Explorer on
the files to be contained in the .zip file. In many cases, it is appropriate
to only grant Everyone Read access to .exe and .dll files, while granting

Warning: Users should be aware that the -B option does not pre-
vent loss of existing data under all circumstances. For exam-
ple, when unzip is run in overwrite-all mode, an existing
``foo~'' file is deleted before unzip attempts to rename ``foo''
to ``foo~''. When this rename attempt fails (because of a file
locks, insufficient privileges, or ...), the extraction of
``foo~'' gets cancelled, but the old backup file is already
lost. A similar scenario takes place when the sequence number
