[tcljava-user] Behaviour of exec in jacl. out.

[Patrick F. <fin...@gm...>]

Running JACL 1.4.2 under AIX 5.3.

How does exec under JACL handle stdout.  Seems to be different to Tcl.
 I would imagine the differences are java related i.e. jacl runs
inside java which has it's own process  running under the OS where as
the Tcl process runs inside the OS with no Java layer in between.
Maybe Jython has the same issues.

The main thing here is that redirect to a file(> EM_run_proxy.log)
does not work under JACL
.
1.  No process id returned.

JACL
******
wsadmin>exec nohup EM_run_proxy.sh -catName CreateSuspects  &
pid0

TCLSH
********

%exec nohup EM_run_proxy.sh -catName CreateSuspects  &
876612
% Sending nohup output to nohup.out.

2.  No redirect to output file.

JACL
*******

wsadmin>exec nohup EM_run_proxy.sh -catName CreateSuspects > EM_run_proxy.log

No file gets created.

TCLSH
********

% exec nohup EM_run_proxy.sh -catName CreateSuspects > EM_run_proxy.log &
876614

EM_run_proxy.log is created and contains stand out.
