A replacement for Windows W2K, XP, W2003, Vista, W2008, W7-32, W7-64, W8-32 and W8-64command.com/cmd.exe that adds many extra features to
file processing. It includes tcc.exe (née 4NT) for
console batch files and a GUI (Graphic User Interface)
equivalent. tcc.exe used to be sold separately. Even the
familiar 4nt.exe is still there, but renamed to tcc.exe. The current version is 16.03.55Last revised/verified:2014-07-13.
It comes in two versions:
Take Command Versions
Take Command Versions
console tcc version only
I have only limited experience with the GUI
component, (which does not appear to do much), though I bought a copy of Take Command
on 2008-03-04. Within that you can download the
32 or 64-bit version. Everything
following is about the tcc console batch component. Take Command/LE has been
It is initially of interest to Java programmers
because it lets you redirect both STDOUT and STDERR to files, pipes or tees. The
feature allows you to redirect the output of javac.exe, i.e. the error
messages, which appear on STDERR, to a file, or to both a file and the console. Why
is that important? Capturing the error messages from javac.exe can be a hassle since
they scroll off the screen faster than you can read them. Ordinary > redirection won’t capture them to a file because they are
going to STDERR, not STDOUT.
Once you have tcc installed you can redirect output:
or pipe output to another utility:
rem pipe stdout to more utility
javac.exe *.java | morerem pipe output of stdout and stderr to more utility
javac.exe *.java |& more
or pipe with a tee to both redirect to a file and pipe:
When using tee with a pipe under tcc, the programs on the two ends of the pipe run
simultaneously, not sequentially as in 4DOS. This means more
starts producing output right away. It does not need to wait until the compile
Programs don’t have to be on the path to start them with tcc. They just need
an Registry App Paths entry so
there is no need to put a directory on the path unless it contains several programs.
This keeps your path short, simple and fast.
You can play with timestamps (improperly
called ages) like this:
REM if myfile.java is newer than myfile.exe,REM i.e. has a bigger timestamp,REM then recompile.REM note the  around parms and lack of () around the if expression.if %@FILEAGE[myfile.java] GT %@FILEAGE[myfile.exe] call recompile myfile
tcc Pet Tricks
Here are some of the sorts of tricks I use with tcc.
To calculate, add, subtract, multiply, divide use the @EVAL function.
Recursive Directory Processing
Here an example of recursively descending a directory tree and processing each
directory it finds.
This script compares two directories to detect missing, older, newer, or extra
Here is an example of an iteration over all directories in a tree and within that
over each file. This is a useful script to keep to trees in synch by deleting files
in the destination that no longer exist in the source.
Recursively Running a Utility on a Directory Tree
Here is the bloutall.btm script I use frequently. It runs
the blout.exe utility on every file in the current
directory, or optionally on every file in the directory tree. It only runs it on
files with an extension that implies than contain readable text. blout.exe gets rid of excess blank lines and normalises line ending
separators. I could also have implemented it with the simpler GLOBAL command.
Copying just selected Dirs from one tree to Another
Often you don’t want to process a whole directory true, just do the same
thing to some or most of the directories in it. Here is an example where I provide a
list of dirs I want to copy to the corresponding spot in another tree.
The syntax is quite warty, with ugly elements borrowed from Microsoft DOS (Disk Operating System) and Windows command languages and FØRTRAN. The syntax is quite irregular
and ad hoc. Like Topsy, it just growed. I hope some day they repackage the functionality in a cleaner language that looks like Java or is Java where you can compile
your scripts for compactness and speed.
copy /u will replace older files and add new ones.
copy /c will just replace older files.
Colour control of the console is broken. See below.
The biggest problem with tcc is you may not distribute it to you customers in
any way. If they want to run your *.bat files they must
buy and install tcc for themselves. There is no such thing an a tcc runtime.
There is a version of tcc for Windows W95, W98 and Me
I have encountered only one bug in CDD (Change Disk and Directory)
/S DE will not work unless a C: drive exists. You
can work around that by providing it with a dummy one with SUBST
I think this is now fixed but in version 4.01,
wildcards on long file names will be performed on both long and short filenames, so
often you get two matches on the same file! The result in you often notice tcc
running a utility twice when you use wildcards.
You can install it as your official command processor, replacing cmd.exe with by setting the COMSPEC
environment variable to:
With Vista, the registration key can mysteriously disappear. Use the inikey
version to keep it in a file instead of the flaky registry.
With Vista, the defender will keep asking you for permission to run tcc. Change
the short cut you use to invoke tcc in the for all users option to tell it
not to run as administrator.
You can set up tcc as your default command processor by
setting the SET environment COMSPEC parameter to:
You can also do this more easily with X:\Program
Use the OPTION command
to set the following parameters:
register, where you put your registration key.
command line: extended directory search: 2. This
a very useful command to jump to a directory on any drive just by typing a few
letters of its name. It creates an auxiliary list of all directories in
, or possibly is the LOCALAPPDATA directory,
or even the
X:\Program Files\JPSoft\TCMD14x64 directory. It is just a
text file, which can be used to compose a list of directories to backup or
directories to erase. You will probably want to unhide your
directory to make the list more complete.
NTSC (National Television System Committee aka Never The Same Colour)

tcc colour scheme
file might look like this:
Each window controlled by tcc can
override the OPTION properties independently. In the upper left corner of each
window, click properties:

Window size: 100 × 40
Edit options: insert mode and quickedit mode
Screen background: 200-255-255 : pale cyan. You can
also configure the popup colour here.
Run tccbatch.btm to associate .bat, .btm and/or .cmd

You can configure the size of the CDD

surprise since 4DOS/tcc/TakeCommand has been keyboard driven since the

cores, you can speed things up by dividing your work between several
*.btm files and running the simultaneously. You then need to launch
them, wait for them to finish and keep them from interfering with each other. See
on how to coordinate tasks.
Controlling the colours of the foreground and background colours in Windows/Take
Command console is baffling. Part of the problem is a legacy that goes back to
DOS/4DOS days and hardware capable of only monochrome or 16 colours. I get the
console colours behaving and as I want and they suddenly change all by themselves to
unsuitable values. It is so frustrating I could spit. To start, let us look at
eight places you can exert influence:
TCC (Take Command Command line) ⇒ Option ⇒
Windows ⇒ ConsolePalette. You would think this would define the
16 custom colours you can use for foreground and
background colours. It is not quite that simple.
TCC ⇒ Option ⇒
Windows ⇒ ANSI (American National Standards Institute). You
would think this would give you wider choice of colours.
TCC ⇒ Option ⇒
Windows foreground and background colours. These would
be the defaults for all consoles.
The Take Command Option menu.
. The palette colours are encoded here as decimal numbers.
When a console is running, you can right click the top
bar ⇒ properties ⇒ colour. You see a palette of 16 colours.
You can define each palette entry with a 24-bit colour,
and assign palette colours to foreground or background. Then click apply.
This looks very
straightforward, but it simply does not work the way you would expect. If you
select a colour not on the palette, it will revert to a colour on the palette the
next time you open the window. Sometimes changing the palette has no effect.
Sometimes it disturbs the colours of other consoles. Sometimes you get some quite
different colour from the one you asked for. Sometimes you get a garish primary colour.
I would have thought, when you modify
a running console, you must be modifying a *.lnk file. I
discovered Windows sometimes creates temporary *.lnk files
corresponding to *.bat or *.btm
However, these *.lnk files are missing the menu items to
control colours (though they may internally have colour-controlling fields). I thought perhaps Windows/Take Command might be hiding the colour
information in the registry somewhere, but I could not find it.
Similar to a running console, you can right click on a shortcut *.lnk file and configure its colours, so long as it is on the desktop,
not on the task bar.
You can embed commands like this is your *.bat and *.btm files.
cls bright white on blue
This gives you dynamic control of colours, but you are limited to a very small set of inappropriate colours.
Try fooling around with all eight places before you give up.
Given that the whole console colour mechanism is broken, here is a strategy to
make it work reasonably stably.
Inside the TCC OPTION command, configure your palette with the 16 colours you want to use
as foreground and background colours in your consoles. Never again
Catch consoles running and configure them. Just select from the palette. Do
not define any new colours.
In future, the format of the *.lnk file should be changed so that you can configure regular, error and popup forground
and background colours with 24-bit colours, completely independent from any other *.lnk file,
without being limited to a 16-colour palette. Nothing you can do to one
*.lnk file should
screw up the colours in another. The colours should not change unless you explicitly change them.
Perhaps you should be allowed a layer of indirection, e.g. specify colours to be the same as some other *.lnk.
Then you could change the colour scheme of many
*.lnk files by changing one master *.lnk.
For now, you can set the colours to anything you want, but they will stick for only one session. What a flipping mess! As my math professor
to say Somebody should be shot.
To compute an arithmetic expression, you must you the @EVAL function.
If TCC complains about your setting for TCStartPath, the problem may be that some other utility has the whole drive containing that directory
