asterisk users - Jul 2006 - [tip]semicolon trouble: System($(sleep 4; cp 1.call out)&) not working, but System($( sleep 4 && cp 1.call out)&) ; )

Salve *!

Semicolon inside extensions.conf marks the start of the comment,
so no chance to use it to build a list of bash comments -
alternative: && and || see:
	 man bash | grep -A 33 Lists


When I try to use my (GSM)mobile to initiate a callback, I found
out that it would be good, if this callback is delayed with some
seconds - and I don't want to put it in a external skript
	System ($(delayed-callback.sh) &)
because this would be not so clear, IMHO.

BTW, I use "$(command1; command2) &" to send the commandlist 
"command1; command2" into the background, asterisk would go on
with the dialplan without waiting for finish both commands.

BUT System($(sleep 4; cp 1.call out)&) Is not working,
the trick to build a commandlist without ";" is:
        Sytem($( sleep 4 && cp 1.call /var/spool/asterisk/outgoing)
&)


Have a nice weekend,
rob



PS: To do not make noise with small tips like this, like
    ("hey I'm a newbee, I have found out somethink usefull..."),
    where are the best places to look first if this ideas are
    already known and documentated?
    Inside the asterisk Handbook was no tip to deal with ";"
    inside "Sytem()"......
   
    And excuse me to send my question about vserver and colored CLI
    twice - I didn't got my mails from the listserver and I thought
    I killed it - in future I will look there first.

However you should not copy to the outgoing queue. You should mv a file
there.

exten => 100,1,System(touch /tmp/file1 \; touch /tmp/file2) works for me.

Note that && and || are logical operators, so that if the first
command fails (speaking bashisem: return non zero value) and you used
the && operator then the second command won't run. where as
';' simply
means "run them all, one after the other".

Here, too ;)

Erghhh, I should played with "\" before send noise to this list...
But thank you - your hint should be add to a documentation of 
System()
> Note that && and || are logical operators,
right - for this reason I quotet man bash ;)


Ok \; is working fine - I just have modificated my vim syntax
highlighting:

-- syn match       asteriskComment         ";.*" contains=asteriskTodo
++ syn match       asteriskComment         "[^\\];.*"
contains=asteriskTodo

And BTW for highlighting MP3Player() add:

++ syn match       asteriskApp             ",\zsMP3[a-zA-Z]\+\ze(" 

Greetings,
rob
