Free dec software for linux

dsync is a tool for merging or synchronizing contents of two directories, or just for backups.
dsync project is written in Perl. dsync is inspired by Dan Kogais psync.
I sought something similar to (but more robust than!) the legacy PowerMerge programs available some years ago for classic releases of Mac OS. Dan Kogais nifty psync and supporting MacOSX::File modules seemed like a great start.
Having some time during the lull of the holiday season, I cobbled together Dsync. With Dsync, I attempted to capture the feature set of PowerMerge with the foundation of psync and a few ideas for improvement.
This is an early release. I use it on my systems with some degree of success, but the tool is far from well-tested, predictable, or reliable. Please treat it as development-grade software and help me improve it with your feedback.
While Dsyncs current focus aims exclusively at Mac OS X and its underlying idiosynchracies, I expect that it would be trivial to modify Dsync to work under any unix-like OS.
Installation:
Copy the program to wherever it is easily accessible:
$ cp dsync /usr/local/bin/
Make sure the executable bit is set:
$ ls -l /usr/local/bin/dsync
-rwxr-xr-x 1 root root 24841 Dec 25 13:54 /usr/local/bin/dsync
if not, then set it:
$ chmod +x /usr/local/bin/dsync
If you have Perl installed elsewhere than /usr/bin, then create a symbolic link:
$ cd /usr/bin
$ ln -s /usr/local/bin/perl
[or wherever you keep Perl]
You will also need MacOSX::File by Dan Kogai:
< http://search.cpan.org/dist/MacOSX-File/ >
To get started, take a look at dsync.html included with this distribution or type:
$ perlpod /usr/local/bin/dsync
[or wherever you stashed dsync]
Enhancements:
- Added an option for lax synchronization to foreign file systems.

The benchmark program takes less than 10 minutes to run (on most machines) and compares the system it is run on to two benchmark systems (a Dell Pentium 90 with 256 KB cache running MSDOS and an AMD K6/233 with 512 KB cache running Linux).

The archive contains the complete source, documentation, and a binary (Linux elf). The source has been successfully compiled on various operating systems, including SunOS, DEC Unix 4.0, DEC OSF1, HP-UX, DEC Ultrix, MS-DOS, and of course Linux.

This release is based on the Unix port of beta release 2 of BYTE Magazines BYTEmark benchmark program (previously known as BYTEs Native Mode Benchmarks). The port to Linux/Unix was done by Uwe F. Mayer.

Additional changes to the code were made to make the code work with egcs compiler and to make the software packagable. This is a CPU benchmark providing indexes for integer, floating, and memory performance. It is single-threaded and is not designed to measure the performance gain on multi-processor machines.

Running a "make" will create the binary if all goes well. It is called "nbench" and performs a suite of 10 tests and compares the results to a Dell Pentium 90 with 16 MB RAM and 256 KB L2 cache running MSDOS and compiling with the Watcom 10.0 C/C++ compiler.

If you define -DLINUX during compilation (the default) then you also get a comparison to an AMD K6/233 with 32 MB RAM and 512 KB L2-cache running Linux 2.0.32 and using a binary which was compiled with GNU gcc version 2.7.2.3 and GNU libc-5.4.38.

The algorithms were not changed from the source which was obtained from the BYTE web site at http://www.byte.com/bmark/bmark.htm on December 14, 1996. However, the source was modified to better work with 64-bit machines (in particular the random number generator was modified to always work with 32 bit, no matter what kind of hardware you run it on).

Furthermore, for some of the algorithms additional resettings of the data was added to increase the consistency across different hardware. Some extra debugging code was added, which has no impact on normal runs.

In case there is uneven system load due to other processes while this benchmark suite executes, it might take longer to run than on an unloaded system.

This is because the benchmark does some statistical analysis to make sure that the reported results are statistically significant, and an increased variation in individual runs requires more runs to achieve the required statistical confidence.

This is a single-threaded benchmark and is not designed to measure the performance gain on multi-processor machines.

Date::Manip is a date manipulation routines.

SYNOPSIS

use Date::Manip;

$version = DateManipVersion;

$date = ParseDate(@args);
$date = ParseDate($string);
$date = ParseDate($string);

@date = UnixDate($date,@format);
$date = UnixDate($date,@format);

$delta = ParseDateDelta(@args);
$delta = ParseDateDelta($string);
$delta = ParseDateDelta($string);

@str = Delta_Format($delta,$dec,@format);
$str = Delta_Format($delta,$dec,@format);

$recur = ParseRecur($string,$base,$date0,$date1,$flags);
@dates = ParseRecur($string,$base,$date0,$date1,$flags);

$flag = Date_Cmp($date1,$date2);

$d = DateCalc($d1,$d2 [,$errref] [,$del]);

$date = Date_SetTime($date,$hr,$min,$sec);
$date = Date_SetTime($date,$time);

$date = Date_SetDateField($date,$field,$val [,$nocheck]);

$date = Date_GetPrev($date,$dow,$today,$hr,$min,$sec);
$date = Date_GetPrev($date,$dow,$today,$time);

$date = Date_GetNext($date,$dow,$today,$hr,$min,$sec);
$date = Date_GetNext($date,$dow,$today,$time);

$name = Date_IsHoliday($date);

$listref = Events_List($date);
$listref = Events_List($date0,$date1);

$date = Date_ConvTZ($date);
$date = Date_ConvTZ($date,$from);
$date = Date_ConvTZ($date,"",$to);
$date = Date_ConvTZ($date,$from,$to);

$flag = Date_IsWorkDay($date [,$flag]);

$date = Date_NextWorkDay($date,$off [,$time]);

$date = Date_PrevWorkDay($date,$off [,$time]);

$date = Date_NearestWorkDay($date [,$tomorrowfirst]);

&Date_Init();
&Date_Init("VAR=VAL","VAR=VAL",...);
@list = Date_Init();
@list = Date_Init("VAR=VAL","VAR=VAL",...);

The above routines all check to make sure that Date_Init is called. If it hasnt been, they will call it automatically. As a result, there is usually no need to call Date_Init explicitely unless you want to change some of the config variables (described below). They also do error checking on the input.

The routines listed below are intended primarily for internal use by other Date::Manip routines. They do little or no error checking, and do not explicitely call Date_Init. Those functions are all done in the main Date::Manip routines above.

Because they are significantly faster than the full Date::Manip routines, they are available for use with a few caveats. Since little or no error checking is done, it is the responsibility of the programmer to ensure that valid data (AND valid dates) are passed to them. Passing invalid data (such as a non-numeric month) or invalid dates (Feb 31) will fail in unpredictable ways (possibly returning erroneous results). Also, since Date_Init is not called by these, it must be called explicitely by the programmer before using these routines.

In the following routines, $y may be entered as either a 2 or 4 digit year (it will be converted to a 4 digit year based on the variable YYtoYYYY described below). Month and day should be numeric in all cases. Most (if not all) of the information below can be gotten from UnixDate which is really the way I intended it to be gotten, but there are reasons to use these (these are significantly faster).

$day = Date_DayOfWeek($m,$d,$y);
$secs = Date_SecsSince1970($m,$d,$y,$h,$mn,$s);
$secs = Date_SecsSince1970GMT($m,$d,$y,$h,$mn,$s);
$days = Date_DaysSince1BC($m,$d,$y);
$day = Date_DayOfYear($m,$d,$y);
($y,$m,$d,$h,$mn,$s) = Date_NthDayOfYear($y,$n);
$days = Date_DaysInYear($y);
$days = Date_DaysInMonth($m,$y);
$wkno = Date_WeekOfYear($m,$d,$y,$first);
$flag = Date_LeapYear($y);
$day = Date_DaySuffix($d);
$tz = Date_TimeZone();

Libsndfile is a C library for reading and writing files containing sampled sound (such as the Apple/SGI AIFF format and MS Windows WAV) through one standard library interface.
The library was written to compile and run on a Linux system but should compile and run on just about any Unix (including MacOSX). It can also be compiled and run on Win32 systems using the Microsoft compiler and MacOS (OS9 and earlier) using the Metrowerks compiler. There are directions for compiling libsndfile on these platforms in the Win32 and MacOS directories of the source code distribution.
It was designed to handle both little-endian (such as WAV) and big-endian (such as AIFF) data, and to compile and run correctly on little-endian (such as Intel and DEC/Compaq Alpha) processor systems as well as big-endian processor systems such as Motorola 68k, Power PC, MIPS and Sparc. Hopefully the design of the library will also make it easy to extend for reading and writing new sound file formats.
Main features:
- Ability to read and write a large number of file formats.
- A simple, elegant and easy to use Applications Programming Interface.
- Usable on Unix, Win32, MacOS and others.
- On the fly format conversion, including endian-ness swapping, type conversion and bitwidth scaling.
- Optional normalisation when reading floating point data from files containing integer data.
- Ability to open files in read/write mode.
- The ability to write the file header without closing the file (only on files open for write or read/write).
- Ability to query the library about all supported formats and retrieve text strings describing each format.
Enhancements:
- A C++ header file which acts as a wrapper around the C API was added.
- The documentation on using a precompiled Win32 DLL was fixed.
- Minor bugfixes and cleanups were done.

DNS Domain Expiration Check is a utility for checking DNS domain expiration dates.

domain-check queries WHOIS data in realtime, and can be integrated with cron to provide e-mail notifications prior to a domain expiring.

The first example will print the expiration date and registrar for daemons.net:

$ domain-check.sh -d daemons.net

Domain Registrar Status Expires Days Left
----------------------------------- ----------------- -------- ----------- ---------
daemons.net INTERCOSMOS MEDIA Valid 13-feb-2006 64


The second example prints the expiration date and registrar for the domains listed in the file "domains":

$ domain-check.sh -f domains

Domain Registrar Status Expires Days Left
----------------------------------- ----------------- -------- ----------- ---------
sun.com NETWORK SOLUTIONS Valid 20-mar-2010 1560
google.com EMARKMONITOR INC. Valid 14-sep-2011 2103
daemons.net INTERCOSMOS MEDIA Valid 13-feb-2006 64
spotch.com GANDI Valid 03-dec-2006 357


The third example will e-mail the address admin@daemons.net with the domains that will expire in 60-days or less:

$ domain-check -a -f domains -q -x 60 -e admin@daemons.net

skill sends signals to processes given any combination of user names, ttys, commands, and pids and snice changes the priority of processes (given the same).
They are similar to kill(1) and renice(8), but the commandline is order-independent. There are also verbose, search, and interactive modes of operation.
Both programs run under a variety of operating systems, including:
Apple Darwin 5.4
AT&T SysVR4, SysVR4.2, SysVR4.2MP
4.2BSD, 4.3BSD, 4.4BSD (and many PC variants)
Cygwin 1.5 (uses Linux)
Mach 2.6, 3.0
DEC Ultrix 2.2, 4.1-2
DEC AXP OSF/1
DEC/Compaq Tru64 Unix V3.2D-2, T3.2F-1, V4.0, V5.0-1B
Encore UMAX 4.2
FreeBSD 2.0-2, 3.1, 4.4-11, 5.0-3, 6.0-1
HP-UX 6.5, 7.0, 8.0, 9.0-5, 10.1-20, 11.0-23
IBM AIX 3.1-2, 4.1, 5.2
IBM AOS 4.3
Linux 1.0-2, 2.1, 2.2, 2.4
MIPS UMIPS 2.1
NeXT OS 1.0, 2.1
NetBSD 1.3-5
OpenBSD 2.6, 3.0
Pyramid OSx 4.0
SCO UnixWare 7.0.1

Sequent Dynix 3.0-1
SunOS 2, 3, 4.0-1, 5.1-10
Enhancements:
- skill and snice now act on each process only once (for systems like BSD that return the same Process ID multiple times, once for each instantiated thread).
- Support has also been added for FreeBSD 6.2 and HP-UX 11.31.

Ytree project is a (curses-based) file manager similar to DOS Xtree.
It was made for browsing filesystems and archives (RAR/SPM/RPM/TAR/ARC/LHA/ZIP/ZOO).
Ytree is reported to run on following platforms:
SYSV R3.2/R4
Interactive UNIX
Linux V2.2
NeXTstep 2.1
