• NYADOS - DOS Shell for DOS,Windows95,98,Me
• NYACUS - CUI Shell for WindowsNT,2000,Xp
• NYAOS2 - OS/2 Shell for OS/2 Warp

These are the commandline-shell which run on DOS,Windows,OS/2 Warp.

• Command-line Editing like tcsh
• Filename completion optimally for Windows-filesystem.
  • ignore case of filename.
  • append double-quotation to filename which has a space.
  • select '/' or '\' automatically to append as path demilitor .

for instance:

    cd /prog --[Type TAB]--> cd "/Program Files/"
    cd \prog --[Type TAB]--> cd "\Program Files\"

• colored ls
• history
• alias
• key customizing
• back-quote
• copy from/to clipboard

1. Put NYACUS.EXE on the directory pointed %PATH%.
2. Put _nya to
   • the current directory
   • or the directory pointed %HOME%
   • or the root directory of the current drive.

_nya is read when NYACUS.EXE start.

In _nya , your script read NYACUS's parameter with %1,%2...

-f SCRIPTFILENAME ARG1 ...

Execute SCRIPTFILENAME by NYA*S. It does not begin an interactive cui-shell. It is the same as `source SCRIPTFILENAME' in NYA*S but not to load configuration file. ( %HOME%/_nya )

-r SCRIPTFILENAME

Execute SCRIPTFILENAME instead of %HOME%/_nya and begin an interactive cui-shell.

-e "COMMAND"

execute SCRIPTFILENAME. It does not begin an interactive cui-shell.

-o VAR=VALUE

let VALUE to shell variable VAR.

-more-unix

enable history expansion(= 'option +history' ), enable brace expansion(= 'option +bracexp' ), enable command substitution(= 'option +backquote' ), and set prompt like bash(= 'option prompt "[\w] $ "' ). if environment variable HOME is not defined, do 'set HOME=%HOMEDRIVE%%HOMEPATH%'

-futils-alias

emulate mv and cp with CMD.EXE build-in command and aliases. This option equals to execute commands below :

    alias mv "move /-Y $@"
    alias cp "copy /-Y /B /V $@"
    alias rmdir "rmdir $@"
    alias rm "del $@"
    alias grep "findstr $@"

UP ^P

TAB ^I ^D

Others

Command 'option +history' enable this expansion.

These suffixes can modify history expansion behavior.

2> FILENAME

switch standard-error-output to write FILENAME.

2>> FILENAME

2>&1

switch standard-error-output to standard output

2>&-

COMMAND1 |& COMMAND2

link COMMAND2's standard-input with both COMMAND1's standard-output and standard-error-output.

With `option +backquote', replace `COMMAND ARGUMENTS..` to the strings which they output at executing.

For instance:

To back up all files under the current working directory.

    [C:work] $ option +backquote
    [C:work] $ foreach i `dir /b /s`
    [C:work] $    copy %i% %i%-backup
    [C:work] $ end

Double backquotes `` are replaced to one backquote ` between backquotes.

    [C:work] $ echo `echo 1``2`
    1`2
    [C:work]

To diable replacing, do 'option -backquote'.

Function was available.

    FUNCTIONNAME{
	COMMAND1
	COMMAND2
	    ;
	COMMANDn
    }

• Don't insert space between FUNCTIONNAME and brace-mark '{'
• Parameters can be able to be refered with %1,%2..%*, $1...$9,$*.

For example

    which{
	foreach dir . ${PATH.split}
	    foreach ext .com .exe .bat .cmd
		if exist %dir%\%1%ext% then
		    echo found %dir%\%1%ext%
		endif
	    end
	end
