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 ???
