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 ???

volrmmount

volrmmount(1)							   User Commands						     volrmmount(1)

NAME

       volrmmount - call rmmount to mount or unmount media

SYNOPSIS

       volrmmount [-i | -e]  [name | nickname]

       volrmmount [-d]

DESCRIPTION

       The  volrmmount	utility  calls	 rmmount(1M)  to, in effect, simulate an insertion (-i) or an ejection (-e). Simulating an insertion often
       means that  rmmount will mount the media. Conversely, simulating an ejection often means that  rmmount will  unmount  the  media.  However,
       these actions can vary depending on the rmmount configuration and media type (see rmmount.conf(4)).

       For  example, if you use the default /etc/rmmount.conf and insert a music CD, it will not be mounted. However, you can configure rmmount so
       that it calls workman whenever a music CD is inserted.

       This command allows you to override Volume Management's usual  handling of media (see EXAMPLES below).

OPTIONS

       The following options are supported:

       -i	Simulates an insertion of the specified media by calling rmmount.

       -e	Simulates an ejection of the specified media by calling rmmount.

       -d	Displays the name of the default device for volrmmount to handle. This device is used if no name or nickname is supplied.

OPERANDS

       The following operands are supported:

       name	       The name that Volume Management recognizes as the device's name. See volfs(7FS).

       nickname        A shortened version of the device's name.  Following is the list of recognized nicknames:

       +-----------------------------+-----------------------------+
       |	 Nickname	     |		  Path		   |
       +-----------------------------+-----------------------------+
       |fd			     |/dev/rdiskette		   |

       +-----------------------------+-----------------------------+
       |floppy1 		     |/dev/rdiskette1		   |
       +-----------------------------+-----------------------------+
       |cdrom0			     |/vol/dev/rdsk/cXtYdZ/label   |
       +-----------------------------+-----------------------------+
       |zip0			     |/vol/dev/rdsk/cXtYdZ/label   |
       +-----------------------------+-----------------------------+
       |jaz0			     |/vol/dev/rdsk/cXtYdZ/label   |
       +-----------------------------+-----------------------------+
       |rmdisk0 		     |/vol/dev/rdsk/cXtYdZ/label   |
       +-----------------------------+-----------------------------+

EXAMPLES

       Example 1: Using the volrmmount command

       When Volume Management finds a floppy that contains a filesystem, it calls rmmount to mount it. If you wish to run  tar(1)  or  cpio(1)	on
       that floppy, it must first be unmounted. To unmount the floppy use:

       example% volrmmount -e floppy0

       After volrmmount unmounts the floppy, if you wish to re-mount it (rather than ejecting it and reinserting it) use:

       example% volrmmount -i floppy0

       Notice that if you are using a named floppy, you can use its name in place of floppy0.

FILES

       /dev/volctl	       Volume Management control port

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWvolu			   |

NOTES

       Volume Management (vold) must be running to use this command.
