Monks,

I have a version of Expect 1.15 that I am attempting to use to capture input from commands such as ls -l

However, the input appears to be get chopped as I cannot see all of the files from the listing command. I have been logging the output and also checking the accumulator.

Upon inspection of the Expect module, it appears that it performs a sysread using a fixed number of bytes.

Are there any solutions to capture the full output of a command that might dump quite a bit of output to STDOUT?


Best Regards
Ty

Update:

I used the perl debugger to walk through Expect and then I came up with a solution that works

 
# given an Expect object in $e
# given a command to run in $command 
# given a timeout value in $timeout
# given that command does not print ENDOFCOMMAND to STDOUT

$e->send("$command;echo ENDOFCOMMAND\n");
$e->expect($timeout,[qr/(?<!echo )ENDOFCOMMAND/ => sub { 0;}],
  [qr/(echo ENDOFCOMMAND)/ => sub { exp_continue;}]);

$outputfromcommand = $e->before();
