Seeing output of command over ssh
Hey Guys,

i have a script that generates logs at our isilon storage.

The part of the script is to geneate logs and grep its name:
Code:
VAR=`ssh -o UserKnownHostsFile=/dev/null root@XXX isi_gather_info | grep -i "Package:" | awk '{ print $2 }'`

Now , while this is run, i do not see the status of the logs creatation:

Code:
[XX@XX ~]$ sudo ./isilogs.sh 
Welcome root
Running isi_gather_info on the remote server
The authenticity of host 'XX)' can't be established.
DSA key fingerprint is 5e:2b:f6:80:b6:62:33:78:f5:6f:00:32:a4:f7:d0:f7.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'XX' (DSA) to the list of known hosts.
Password:

The generation works fine , but there is no way to know if the script is actually running or if its hung.

However , when i run this locally on the isilion i can see logs being generated:
Code:


Code:



XX-1# isi_gather_info
Unlocking gather-status
Gather-status unlocked
Error running "isi firmware status"






This may take several minutes.  Please do not interrupt the script.

.....................

Anyone has a clue how can i make this output appear when i run the script on a remove linux server?

Thanks for help in advance

IRSEND(1)								FSF								 IRSEND(1)

NAME

       irsend - basic LIRC program to send infra-red commands

SYNOPSIS

       irsend [options] DIRECTIVE REMOTE CODE [CODE...]

DESCRIPTION

       Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such
       as TV boxes, HiFi sets, etc.

       DIRECTIVE can be:
	  SEND_ONCE	    - send CODE [CODE ...] once
	  SEND_START	    - start repeating CODE
	  SEND_STOP	    - stop repeating CODE
	  LIST		    - list configured remote items
	  SET_TRANSMITTERS  - set transmitters NUM [NUM ...]
	  SIMULATE	    - simulate IR event

       REMOTE is the name of a remote, as described in the lircd configuration file.

       CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file.

       NUM is the transmitter number of the hardware device.

       For the LIST DIRECTIVE, REMOTE and/or CODE can be empty:

	  LIST	 ""    ""   - list all configured remote names
	  LIST REMOTE  ""   - list all codes of REMOTE
	  LIST REMOTE CODE  - list only CODE of REMOTE

       The SIMULATE command only works if it has been explicitly enabled in lircd.

       -h --help
	      display usage summary

       -v --version
	      display version

       -d --device
	      use given lircd socket [/var/run/lirc/lircd]

       -a --address=host[:port]
	      connect to lircd at this address

       -# --count=n
	      send command n times

EXAMPLES

	  irsend LIST DenonTuner ""
	  irsend SEND_ONCE  DenonTuner PROG-SCAN
	  irsend SEND_ONCE  OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
	  irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
	  irsend SEND_STOP  OnkyoAmpli VOL-DOWN
	  irsend SET_TRANSMITTERS 1
	  irsend SET_TRANSMITTERS 1 3 4
	  irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"

FILES

       /etc/lirc/lircd.conf
	      Default lircd configuration file.  It should contain all the remotes, their infra-red codes and the corresponding timing	and  wave-
	      form details.

DIAGNOSTICS

       If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:
       "irsend: could not connect to socket"
       "irsend: Connection refused" (or "Permission denied").

SEE ALSO

       The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory.
