A new release of sharutils, 4.7-2, is available, leaving 4.6.3-1 as
previous.
NEWS:
=3D=3D=3D=3D=3D
This is an update to build against cygwin 1.7, using gcc 4, and to update
the documentation layout to match recommended practice. Using shar on
text mounts continues to have the possibility that line endings on text
files might not be handled the way you want, but if it was truly a text
file, that should not matter to you; the heuristic that shar uses to
decide between text and binary files is whether it contains non-printing
characters. It is safer to use shar/unshar on binary mounts (remembering
that unshar is inherently unsafe). uuencode and uudecode, on the other
hand, work reliably regardless of the underlying mount point. See also
the package documentation found in /usr/share/doc/sharutils/.
DESCRIPTION:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
The sharutils package contains the GNU shar utilities, a set of tools
for encoding and decoding packages of files (in binary or text format)
in a special plain text format called shell archives (shar). This
format can be sent through e-mail (which can be problematic for
regular binary files). The shar utility supports a wide range of
capabilities (compressing, uuencoding, splitting long files for
multi-part mailings, providing checksums), which make it very flexible
at creating shar files. After the files have been sent, the unshar
tool scans mail messages looking for shar files. Unshar automatically
strips off mail headers and introductory text and then unpacks the
shar files.
Note that unshar is inherently unsafe by design, because it executes
arbitrary shell scripts; therefore the creation of shar archives should be
limited to situations where the receiver trusts the sender. However,
uuencode and uudecode are useful in their own right, and are safe to use.
