Perl: Tee system-command to SYSOUT and @array? (not > file)

Hi - Within perl I want to execute a system command. I want to re-direct all the output from the command to a file (@result = `$cmd`Smilie, but I ALSO want the results to be displayed on the screen (system("$cmd");

The reason is this - if the command completes, I want to process the output. If the command -hangs- (trying to debug a system problem), I want the output on the screen so I can see how far the command got.

Any easy way to do this in perl?

Thanks!

uadmin(1M)																uadmin(1M)

NAME
uadmin - administrative control SYNOPSIS
/usr/sbin/uadmin cmd fcn [mdep] /sbin/uadmin cmd fcn [mdep] The uadmin command provides control for basic administrative functions. This command is tightly coupled to the system administration proce- dures and is not intended for general use. It may be invoked only by the super-user. Both the cmd (command) and fcn (function) arguments are converted to integers and passed to the uadmin system call. The optional mdep (machine dependent) argument is only available for the cmd values of 1 (A_REBOOT), 2 (A_SHUTDOWN), or 5 (A_DUMP). For any other cmd value, no mdep command-line argument is allowed. When passing an mdep value that contains whitespaces, the string must be grouped together as a single argument enclosed within quotes, for example: uadmin 1 1 "-s kernel/unix" See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ uadmin(2), attributes(5) On systems, shutting down the system by means of uadmin does not update the boot archive. Avoid using this command after manual editing of files such as /etc/system or driver.conf(4). 11 Apr 2005 uadmin(1M)
