asterisk users - Aug 2005 - echo system command and set the results to a new variable

I am looking to issue a 'System cmd' that will echo the results into  
a new variable -- can anyone tell me the correct way to do this?

example: at the terminal I am currently able to issue this command:  
echo | date > date.txt
I end up with a file called date.txt with the contents: Mon Aug 29  
18:32:45 EDT 2005

I would like to issue a command in my dialplan that puts the date  
into a new variable something like this:
System(echo | date > Set(newVariableName=theDateEchoReturns)

So that the newVariableName=Mon Aug 29 18:32:45 EDT 2005

The objective in this case is to format the date according to the  
Unix Time format listed above.  I am certainly open to other options  
for doing this.  The default ${TIMESTAMP} format doesn't work for my  
needs.

Thanks!

Do you want to run that command in the shell? This pipes the output of
'echo' (with no parameters: just prints a single newline) to date (with
no params, ignores its input anyway) and redirects the output of date
into date.txt .

As expected.

System doesn't do that . chan_backticks does:
http://pbxfreeware.com/app_backticks.c

But then again, I figure that there's a simpler way.

What do you need it for?

Sorry if this wasn't written clearly before.

I want to issue a System cmd in my dialpan that is similar to the  
unix echo command stated above. *EXCEPT* that I want to pipe the  
results into a *new* variable (vs a text file.)

Ideally, what would happen is in my diaplan I would issue the 'echo |  
date' command and pipe the output to a newly created variable with  
the appropriate output.

example:
NewVariable=Mon Aug 29 18:32:45 EDT 2005

Do you know how I can do this?

Thanks!

As far as I know ${EPOCH} would not work because I need the results  
to be similar to this format: Mon Aug 29 18:32:45 EDT 2005
> What about variable ${EPOCH} ?

  Assuming that you want to execute some Unix commands and feedback the 
output as variables to the dialplan in Asterisk this is possible with an AGI 
bash script. Use the 'set variable' command 
http://www.voip-info.org/tiki-index.php?page=set+variable
 You can use the example at 
http://yakko.cs.wmich.edu/~drclaw/asterisk/cidname/ , reuse the framework to 
read the standard AGI variables and rewrite it to your own code.

Michel
