Compress'ed files are not suitable for zutils. The compress format is
not even standardized[1]:
[1]http://pubs.opengroup.org/onlinepubs/9699919799/utilities/compress.html
"The format of compressed files is unspecified and interchange of such
files between implementations (including access via unspecified file
sharing mechanisms) is not required by POSIX.1-2008."
Support for lzma-alone files is being removed from GNU programs. So I do
not plan to include it in zutils.
7zr supports stdin and stdout. From the 7zr man page:
[...]
Maybe the following is even more useful for zutils:
/usr/bin/p7zip: a gzip like wrapper around 7zr.
I plan to implement a configuration file to let the user choose what
decompressor use for each format (a parallel version of the
decompressor, for example). As soon as I find the time to implement it,
I'll try to include support for 7z files with 7zr/p7zip.
And from the unzip man page:
-c extract files to stdout/screen (``CRT'').
Yes, but unzip does not support stdin. Supporting zip files is
incompatible with zutils' goal of decompressing on the fly without
temporary files.

Antonio.
