調試過程：

修改為

Hi,

Your script worked for me with no problems:

#!/bin/kshread file if [ -z "$file" ] thenecho " DID NOT ENTER A FILE NAME " elif [ ! -f "$file" ] thenecho " \t File ' $file ' Doesn't Exists In $PWD Directory \n" elseecho " \t File ' $file ' Exists In $PWD Direcotry \n" fiBTW, it's always a good idea to include the shell invocation on line 1 of your script. I'd surround $file with double quotes "$file"Have you tried the extended test facility - two brackets instead of 1:#!/bin/kshread file if [[ -z $file ]] thenecho " DID NOT ENTER A FILE NAME " elif [[ ! -f $file ]] then

#!/bin/ksh


set -x


export ORACLE_BASE=/opt/oracle11g
export HOME=/home/oracle
export ORACLE_HOME=/opt/oracle11g/product/11.1.0

env

? LSNRLOG=`/opt/oracle11g/product/11.1.0/bin/lsnrctl <<EOF
??? set current_listener yesinuat
????? show trc_directory
??????? EOF`
??????????? ?
??? echo "Listener Log File: $LSNRLOG"

? LSNRLOG=`/opt/oracle11g/product/11.1.0/bin/lsnrctl <<EOF | grep trc_directory | awk '{print $6"/"$1".log"}'
? set current_listener yesinuat
? show trc_directory
? EOF`
????? echo "Listener Log File: $LSNRLOG"


調試過程：

crontab 在調用過程中，只有如下環境變量
PATH=/usr/bin:/usr/sbin:.
LOGNAME=oracle
SHELL=/usr/bin/sh
HOME=/home/oracle
PWD=/home/oracle
TZ=EAT-8


所以需要在你的shell腳本開始加上
##################
. /etc/profile export ORACLE_BASE=/opt/oracle11g
export HOME=/home/oracle
export ORACLE_HOME=/opt/oracle11g/product/11.1.0 ##################

3。######################

man test
