.SH DESCRIPTION
|
|
The \fBpzip\fP program compresses the named file(s) using the Panda
|
|
native compression algorithm (gzip in practice, but with a different
|
|
file header). The compressed versions are written to a file with the
|
|
same name as the original, but the extension .pz added to the
|
|
filename, and the original file is removed (unless the version with
|
|
\fB\-o\fP is used, in which case you can compress only one file, you
|
|
specify the destination file name, and the original file is not removed).
|
|
.PP
|
|
In many cases, Panda can read the resulting .pz file directly,
|
|
exactly as if it were still in its uncompressed original form.
|
|
In fact, unless \fBvfs\-implicit\-pz\fP is set to \fBfalse\fP in your
|
|
Config.prc file, you can also load the file by referencing it with its
|
|
original filename (without the .pz extension), even though it no longer
|
|
exists under that filename, and Panda will find the .pz file and
|
|
transparently decompress it on the fly, as if the original, uncompressed
|
|
file still existed.
|
|
.PP
|
|
Note that if you are adding files to a Panda multifile (.mf file) with the
|
|
.BR multify (1)
|
|
command, it is not necessary to encrypt them separately; \fBmultify\fP has an
|
|
inline encryption option.
|
|
.PP
|
|
\fBpunzip\fP reverses the operation of a previous \fBpzip\fP command.
|
|
It uncompresses the contents of the named source file(s) and removes
|
|
the .pz extension.
|
|
