shell中使用sqlplus及调试相关

#!/bin/bash
echo -n "Enter password for u_test:"
read PASSWD
sqlplus -S /nolog <<EOF
conn u_test/$PASSWD
select * from tab;
exit
EOF

$ chmod +x test5.sh
$ ./test5.sh

六、为了安全从文件读取密码
对密码文件设置权限, 只有用户自己才能读写.

$ echo ‘iamwangnc‘ > u_test.txt
$ chmod g-rwx,o-rwx u_test.txt
$ vi test6.sh

#!/bin/bash
PASSWD=`cat u_test.txt`
sqlplus -S /nolog <<EOF
conn u_test/$PASSWD
select * from tab;
exit
EOF
