Hi Daniel
Thanks for the reply!
Yes, turns out it was all my fault, I had a line feed character (0x0a a.k.a
printf("\n")) in one of the Asterisk channel variables passed via system() /
shell() to my target script.
It seems 13.22.0 (I'm using the same version as you) reacts to a line feed in
the parameter string by not processing or parsing the string any further one
the line feed is encountered.
I removed the line feed (by using "echo -n" instead of just "echo" in a related
BASH script that was providing input to Asterisk also via SHELL) and the
problem disappeared and system() (and shell() itself ) started working
correctly.
So, the moral is just keep the data clean that is fed through SYSTEM() and
SHELL() from having any line-feeds in them.
On Asterisk 1.8 (my previous version) line-feeds in an Asterisk channel
variable dereferenced in a SYSTEM() or SHELL() call did NOT stop parsing of the
rest of the string - so apparently a relevant difference between the two
versions there.
Kind regards,
