ctcl is basically a tclkitsh or tclsh replacement for Windows. It is a console application with TWAPI bound in. Binary download from [L1 ]
The biggest difference from tclsh or tclkitsh is in its accepting scripts from the command line using standard Tcl syntax and some extensions that make interactive use convenient. It allows me to use Tcl as a common command line tool for systems administration, rummaging the disk, pipelining etc instead of keeping track of a hodge podge of standalone tools. Examples are given later.
Without any arguments, ctcl behaves (almost) like tclsh.
If the first argument is a script file, ctcl behaves (almost) like tclsh.
Otherwise, ctcl treats the entire line as a Tcl script. No magic, but very convenient under Windows.
ctcl is still work in progress. Commands and features are liable to drastic change. Suggestions that streamline interactive use are much appreciated.
R:\>ctcl glob * ctcl-prerc.exe ctcl-runtime.exe ctcl.exe ctcl.vfs foo.txt x.tcl
Or, as a standard tclsh shell,
R:\>ctcl ... ctcl> glob * ctcl-prerc.exe ctcl-runtime.exe ctcl.exe ctcl.vfs foo.txt x.tcl ctcl>
tcl::mathop are autoimported
R:\>ctcl * 2 3

R:\>ctcl + {*}[collect [files -pattern *.tcl] eval {file size $_}]
427090twapi commands are also autoimported.
R:\>ctcl get_process_ids -name notepad.exe 3328 1684
ctcl has its own built-in convenience commands.
R:\>ctcl toclip [read stdin] This text will go into clipboard ^Z
Useful as a flexible Tcl based filter.
R:\>cat foo.txt | ctcl string toupper [read stdin]
The command line may have compound commands.
R:\>ctcl + {*}[collect [files -pattern *.tcl] eval {file size $_}]
427090Command may also be continued across multiple lines.
R:\>ctcl foreach pid [get_process_ids -name notepad.exe] {
> puts "Killing PID $pid"
> end_process $pid
> }
Killing PID 2804
Killing PID 2352or more succintly
R:\>ctcl leap [pids notepad] {end_process $_}Some facilities for pretty printing are included. Dump process information...

...or network connections for port 80.

The vast bulk of commands are of course those from Tcl and TWAPI. However, ctcl adds a few convenience commands that are particularly useful in interactive use.
