Unix-like utilities for Windows

After almost 5 years, I rewrote some of these utilities. I received emails from many people that found them useful, and I'm glad they took the time to write me!.

Some of the programs were updated to work with bigger capacity disks, and other were just fixed for some security issues I found.

The source code was cleaned and now compiles under Microsoft Visual Studio 2005 (the previous version was written on Visual Studio 6.0)

These are some Unix-like (they are similar to some tools found in the Un*x world) utilities that I wrote. They run in an NT/2000/XP/2003 operating systems. These tools are command-line based.

I have received several requests for it, so the source code is included now. The tools are being distributed under the GNU General Public License (GNU GPL) terms.

You can find all these tools packed on a single file: LCUtils.zip.

Note: The DOS and 16-bit Windows version are not longer supported, and I removed them from this site

Items with the NEW! logo have new features.
Filename Description Output sample
This is a port from the Unix "mt" command. It gives you some control on a Tape device. It implements commands to rewind the tape, set the block size, forward or back a specified count of blocks, erase the tape, eject the tape, etc. It has only been tested with a DAT drive.
mt - Version 1.0.1

Makes a raw copy of a tape device. It support writing/reading data from/to standard input/output like many Unix tools. It can be used with the GNU tar tools to write or read tar tapes from Unix boxes in a NT box.

Now completly in english! (The previous version was in spanish, but as many users of these tools are international, I decided to use english).

tapecopy - Version 1.5
Copyright (C) 2000-2008, Luis C. Castro Skertchly
Usage: tapecopy [-v] [-b block] [-r] -x|c [-d devname] [-f filename]
  -v : Verbose
  -b : Specify tape block size in bytes (0 = autodetect)
  -r : Rewind tape before start
  -x : Extract data from tape
  -c : Copy data to tape
  -d : Specify the tape device name (default = TAPE0)
  -f : filename from/to where data will be copied

Valid device names are:

Terminates a process using its process ID (PID). The PID can be obtained from the task manager process list or using the "ps.exe" or "psnt.exe" utilities. n/a
Terminates a Windows session and optionally reboots or power down the system. n/a
Gets the boot record of a floppy disk or partition and writes it on a file. Very useful to create entries at the BOOT.INI file.

mkboot32.exe It creates a boot record on a floppy disk or disk partition based on a boot-strap code in a file. Very useful to create MS-DOS boot disks from Windows NT. In order to do that, first get a bootable DOS disk and run "getboot.exe" to get the boot record. Then you can use "mkboot" to write that boot record in a different disk.

D:\>mkboot32 boot.dat A

Displays a Windows Message Box and waits for the user to click the OK button.
This tool is similar to the "ps" command found on every Unix system. It shows a list of the running processes, its Process ID (PID), Parent Process ID (PPID), number of threads running (THR), process priority (PR), and (when possible) the full path to the executable image.

Raw copy tool. It copies raw data from/to a device, just as if it were just another file. It works with floppy disks, CD-ROM (reading only) and tape devices.
For Unix users, it is very similar to do:
dd if=/dev/rfloppy of=filename.dat
D:\>rcopy \\.\CDROM1 cdimage.iso
rcopy - Version 1.2
