每天都检查oracle日志，所以写了一个比较完善的shell，让其自动处理，在运行程序之前，需要在该脚本目录下新建tmp目录
#!/usr/bin/ksh
export LANG=en
#临时目录
tmp_dest=$HOME/check/tmp
#用户名
username=username
#密码
password=password
cd $tmp_dest
sqlplus -s $username/$password<<XFF>/dev/null
set echo on
spool sqlplus.txt
col name format a20
col value format a55
select name,value from v\$parameter where name='background_dump_dest';
spool off
exit
XFF
alert_path_num=$(grep -n "background_dump_dest" $tmp_dest/sqlplus.txt |awk -F":" '{print $1}')
alert_path=$(cat $tmp_dest/sqlplus.txt |sed -n "${alert_path_num}p" | awk -F" " '{print $2}')
first_day=`cat $tmp_dest/first_day.tmp`
d_day=$(date +%e)
if [ $d_day -lt 10 ]
then
