I am confused. If I copy the posted file:

EV = 0x10eb250 (class,   event_handle: 3503519, mc_ueid: 1278629168)

 exists("TRUSTEDALARM");
Local Id: Rem_010965WAP_18504';

p_agrs
[download]

into the file 'input.txt' and then execute the command

perl -e 'while(<>){chomp; last if /p_agrs/;print if /remotely/}' < input.txt

I get the output

msg='script to be execute remotely:

Is this not consistent with what you observe?
