Shell Programming and Scripting

Hello guys, I have been able to open the command prompt (actually COMMAND.COM) from a shell script.
I have used the following piece of code. It is quite amazing, but it does open command.com. To say frankly I don't know how it works. Perhaps you guys do know it.

Code:

echo ^[[17xC:\\COMMAND.COM

As you can see I had to copy COMMAND.COM in the C: directory because when calling it from its original location C:\WINDOWS\system32\COMMAND.COM I get an error message "Access denied". Do you guys have an idea why this is so?

The problem I'm having now is that I am not able to pass a file (+ an argument) as parameter. Error: Too many parameters.

I tried the following:

Code:

echo ^[[17xC:\\COMMAND.COM "C:\myfile\fileparam.dat" "param1"

HELP please!

why dont you use a batch file to get the file from unix serve ( ftp script )

As previously explained, I have to initiate the call from a Unix program. Only when a user activates a button should the file transfer occur.

user click button --> file download happens --> file downloaded to user desktop

1) where is the button available ? ( is it a web page ? -- hosted in unix machine ? )
2) Is file download should happen from unix machine ?
3) User is on the windows machine ?

1) Yes the application is hosted on a Unix machine. The interface is DOS-like. When user presses function key F11, file should be downloaded.
2) Yes the file should be downloaded from the Unix machine onto the user Windows machine, in a specific directory.
3) Yes the user has a Windows machine

Seriously? You're logged into a Unix server, and some echo command opens a command prompt on your windows machine. I'd like more information.

The only way to get a file from Unix to windows is to use one of the available protocols. You need to pick one of these, for example:
ftp
ssh/sftp/scp
samba/smb

Those are protocols that will transfer files between computers.

I can't help but think you are way off base on finding a solution.

Please pick a protocol and post your Unix program. Then we should be able to help.

Yes it does open the command prompt. As I said it is like magical. I don't know how it works, I have used some existing piece of code and it does the trick. But now I have to pass a file as parameter but it is not working?

Most probably the magic lies within the "^[[17x" part. But sincerely I don't know how it actually works.

Below is part of the piece of code, showing what I am trying to do.

Firstly I'm echoing some commands in a text file and then transfer that file on my local pc using kermit.
Secondly, I am supposed to call command.com with a file parameter so as to do some deletion in a specific directory. (not working presently since it is not accepting the file as a parameter)
Lastly, use winscp.com to download the file from Unix onto my Windows machine.

Code:

echo "
option batch on
option confirm off
open $LOGNAME:$PASNAME@$ADR_INT
option transfer binary
get $CFILE C:\\GLWIN\\myfiles\\$FILEPC
close
exit
" > myfile.txt

kermit -s myfile.txt

echo ^[[17xC:\\COMMAND.COM "C:\myfile\fileparam.dat" "param1"
echo ^[[7xD:\\winscp434\\winscp.com /console /script="C:\GLWIN\myfiles\myfile.txt"
