event subsystem variable use in system call
I am learning about the event subsystem. One of my events looks like this: echo bla ${RPT_ALINKS} >> /tmp/blabla = s|T|RPT_NUMLINKS This executes when I connect. The contents of /tmp/blabla is simply bla. I would have expected ${RPT_ALINKS} to have been expanded. Am I assuming functionality that doesn't exist? Lowell
I think your problem is that you are trying to execute from a linux command and the subsystem resides at the asterisk level. Not that you can do it from there but you must address it where it resides. ...mike/kb8jnm ----- Original Message ----- From: "Users of Asterisk app_rpt" <app_rpt-users@lists.allstarlink.org> To:<App_rpt-users@lists.allstarlink.org> Cc: Sent:Tue, 4 Apr 2017 16:39:51 -0700 Subject:[App_rpt-users] event subsystem variable use in system call I am learning about the event subsystem.

Well, I was hoping that asterisk would have a way to expand asterisk variables before the shell gets called ( by the s| syntax ). Apparently, asterisk is passing the command as is and the shell is expanding the variable. On Tue, Apr 4, 2017 at 8:54 PM, <mike@midnighteng.com> wrote:

Start by writing your function from asterisk CLI . When it works, convert it to be called from shell. But you are not going to get a asterisk var contents like you are doing. Linux shell does not know what ${RPT_ALINKS} is unless you carry/import the var from asterisk. Your echo will always be blank. ...mike/kb8jnm ----- Original Message ----- From: "Users of Asterisk app_rpt" <app_rpt-users@lists.allstarlink.org> To: "Users of Asterisk app_rpt" <app_rpt-users@lists.allstarlink.org> Cc: Sent: Wed, 5 Apr 2017 00:09:19 -0700 Subject: Re: [App_rpt-users] event subsystem variable use in system call Well, I was hoping that asterisk would have a way to expand asterisk variables before the shell gets called ( by the s| syntax ).
