RAR is
a
popular
archive format
introduced by WinRAR for
Windows platform, and
ported to Linux (only as extractor) by the same Author of WinRAR Eugene
Roshal.
RAR format is well known for the high compression ratio archives,
strong
encryption and advanced data recovery capabilities (recovery records).
PeaZip, freeware and open source utility, supports by default RAR browsing,
testing and extraction on Linux and Windows, through the open
source implementation rewritten as free software by Igor Pavlov in 7-Zip and
p7zip.
No free software utility is available for create RAR
compressed files: UNRAR is available as free and open source
software for allowing extraction of RAR archives both on Linux and
Windows with the clause of not reverse engineering the code for
implementing RAR compression.
The non reverse
engineering clause about the RAR
compression algorithm apply as well for any rewritten version, so no
free RAR compressor can be created.
So, due to RAR's license constrains, no free software can be written to
be
capable of writing RAR archives (which is required bot for RAR archive
creation and repairing), unless calling Windows-only WinRar's
executables (i.e.
rar.exe), that
requires having WinRar (shareware, not freeware) downloaded and
installed as a separate product.
Please note that WinRar license's time trial legal limitations apply to
any part of the package (as i.e. rar.exe) as well, even if it does not
display the
warning screen as the GUI executable.
Creation
of RAR archives from PeaZip
With WinRar installed you can use PeaZip's "Custom" archive type
interface to use rar.exe to create
RAR
format archives through PeaZip's GUI: chose "Custom" format in
compression dialog and the
first time go to "Advanced" tab to tell PeaZip how to use the executable
1 - locate where the rar.exe executable is in your system, in
"Executable" filed
2 - write a (which stands for create archive) in "Parameters" filed
3 - select the second entry in "Syntax" dropdown menu: "parameters,
output, input"
Now any time you will select "Custom" format compression PeaZip will
automatically use the syntax rar.exe
a
nameofthearchive nameoftheinputfiles
Please note that rar.exe command line syntax is not a 1:1 replacement
of WinRar features, especially worth of notice is that "a" command
creates the archive storing full paths (and creation storing relative
paths option is not even featured) while WinRar GUI application creates
by default archives storing relative paths.
