stderr stdout to a log file
I originally wrote my script using the korn shell and had to port it to bash on a another server. My script is working find for backing up but noticed that now after the move, I am not getting any output to my log files.

Using Korn shell, this worked for me for some odd reason. This was sending stdout and stderr to a file:

Code:
find /home/testuser -depth  | cpio -oavc | gzip > /media/backup_drive/test.cpio.gz 2> /media/backup_drive/inc$date.log


Here is the line in the script where I expect to see any error go to my errout.log

Code:
find /home/testuser -depth | cpio -oavc | gzip > /media/backup_drive/test.cpio.gz 2> /media/backup_drive/errout.log

in my errout.log its all garbage. I tried everything, stdout and stderr to a log file but the same gargage:

Code:
find /home/testuser -depth  | cpio -oavc | gzip > /media/backup_drive/test.cpio.gz 2>&1 >/media/backup_drive/errout.log

Code:
find /home/testuser -depth  | cpio -oavc | gzip > /media/backup_drive/test.cpio.gz  /media/backup_drive/errout.log 2>&1

Any ideas ???

gems-server

GEMS-SERVER(1)							gems documentation						    GEMS-SERVER(1)

NAME

       gems-server - Transmit a shell session in real time.

SYNOPSIS

       gems-server [-ip ip] [-port p] [-maxconn n] [-wait m] [-log dest] [-noscript] [-script_bin script]

       gems-server -h | -v

DESCRIPTION

       Transmits a shell session to be shown in real time in various different computers or terminals.

       gems-server  transmits data in real time to clients via a network connection. Each one of these clients must run the gems-client(1) program
       to establish connection and receive the transmitted data. Clients can connect and disconnect at any given time, but  of	course	they  will
       only receive the data that is transmitted while they are connected (just like a radio transmission/reception system).

       The  gems  system is normally used to transmit a console session and show it in various computers at the same time, but it is also possible
       to transmit any other kind of data.

OPTIONS

       -ip    IP address where connections will be accepted.

       -port  TCP port. Default: 6666.

       -maxconn
	      Do not accept more than n simultaneous clients. Default: 25.

       -wait  Wait until m clients are connected before starting the transmission. This is useful to ensure that the first m clients will  receive
	      all data transmitted. The default behavior is to start transmission immediately, without waiting for client connections.

       -log   By  default,  the server does not write log messages. This option configures the destination of logs. The dest argument can be `sys-
	      log' (to log through syslogd(8)), `stderr' (to log through standard error output), or it can be an arbitrary filename (log  messages
	      will be appended to the file, if it exists).

       -noscript
	      By  default,  the  server  executes the script(1) program to take terminal data and transmit it. When this option is used the server
	      will not run script, and data will be read form standard input.

       -script_bin
	      Specifies the location of the script(1).	program. Default: /usr/bin/script.

       -h     Show a short help message.

       -v     Show version information.

FILES

       /var/lock/gems-server.PORT
	      Lock file.  gems-server creates this file on initialization and deletes it on exit. PORT is replaced by the TCP  port  used.   gems-
	      server will not run if this file is already present in the system.
