Question There's problem with shell script...Help me~

Hello, guys...

I'm new to IBM AIX server admin. Actuall, I administrate Oracle 10g on it.

*SYSTEM INFO
- IBM AIX 6 Powerpc
- Oracle 10g R2 (10.2.0.4.0 - 64bit)

I wrote a script like bellow...

Code:
DATE='date'
cp /oracle/product/10g/network/log/listener_temp.log /oracle/product/10g/network/log/listener_temp_$DATE

cat /dev/null > /oracle/product/10g/network/log/listener_temp.log

# compress -vf /oracle/product/10g/network/log/listener_temp_$DATE

I declare a variable DATE at first line and result was below...

Code:
-rw-r-----    1 oracle   dba               0 Apr 09 14:26 listener_temp.log
-rw-r-----    1 root     system            0 Apr 09 14:26 listener_temp_date

I expected "listener_temp_20100408" like this.
However, result was like below "listener_temp_date"

what's problem?

Change the variable diclaration in code
DATE='date' # not corect
use
DATE=`date`

Do not use the backticks ("`"), as they are there only for backward compatibility and should not be used if more modern means are available. Use "$(command)" instead of "`command`":

Code:
date="$(date +'%Y%m%d')"

I hope this helps.
