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 = `$cmd`
, but I ALSO want the results to be displayed on the screen (system("$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!

openipmicmd
openipmicmd(1) An IPMI Command Interface openipmicmd(1)
NAME
openipmicmd - An IPMI Command Interface
SYNOPSIS
openipmicmd [-k entry-to-execute] <connection parms>
DESCRIPTION
The openipmicmd program allows a user to execute direct IPMI commands. It can work with direct interface with the OpenIPMI driver or with
IPMI LAN interfaces.
OPTIONS
-k entry-to-execute
Execute a single command an exit.
<connectionparms>
The parameters for the connection depend on the connection type. These are all described in openipmi_conparms (7)
COMMANDS
Once up, you can execute commands in the user interface. Note that commands and responses are asynchronous, you issue a command and the
interface returns immediately. When the response comes back, it will be dumped on your console. That's a little strange looking, but IPMI
is ansychronous underneath. Note that the -k option is synchronous, it will wait for the response or a timeout before returning.
0f lun netfn cmd [data1 [data2 ...]]
Send a command to the BMC you are connected to.
channel [ipmb] IPMB-addr lun netfn [seq] cmd [data1 [data2 ...]]
Send a command to a device on the IPMB bus. The "ipmb" string is optional. The seq must be provided if the netfn is a response (an
odd number). It must be the same sequence number that came in on the command in the "Command Sequence = seq" part of the command.
channel 00 IPMB-addr lun netfn cmd [data1 [data2 ...]]
Send a broadcast command to a device on the IPMB bus.
channel lan handle remote-swid local-swid lun netfn cmd [data1 [data ...]]
Send a command to a device over a LAN channel. Note that this not the same as a LAN connection. This sends a message through a
local BMC to a remote system that is hooked up with a LAN connection.
test_lat count command
Executes the given commands (one of the previous commands) count times and gives the average time per command to execute. Note that
"count" is hexadecimal.
help Display some help.
regcmd netfn cmd
Register to receive the given command. If the driver receives an external command, it will print it out. This only works with sys-
tem interface connections, it will not work on LAN connections.
unregcmd netfn cmd
Remove a command registration.
SEE ALSO
ipmi_ui(1), ipmilan(8), openipmi_conparms(7)
KNOWN PROBLEMS
The asychronous nature of the program can be annoying.
