Oracle 用于询问用户名和路径存储文件的shell脚本

我需要一个shell脚本来请求用户名和路径将expdp文件存储在指定的路径中。请帮帮我。下面是我的脚本

#!/bin/sh

STARTTIME=`date`
export ORACLE_SID=test
export ORACLE_HOME=`cat /etc/oratab|grep ^${ORACLE_SID}:|cut -d':' -f2`
export EXPLOG=expdp_${ORACLE_SID}.log
export EXPDIR=/expdir
export PATH=$PATH:$ORACLE_HOME/bin
DATEFORMAT=`date +%Y%m%d`
STARTTIME=`date`

# Data Pump export
expdp  system/manager content=ALL directory=expdir dumpfile=expdp_`echo $ORACLE_SID`_%U_`echo $DATEFORMAT`.dmp full=Y logfile=$EXPLOG
#expdp export/export content=ALL directory=expdir dumpfile=expdp_`echo $ORACLE_SID`_%U_`echo $DATEFORMAT`.dmp schemas=santhosha logfile=$EXPLOG
ENDTIME=`date`

/home/oracle/deleteold.sh > /backup/expdir/deleteold.log 2>&1

这将有助于：

#!/bin/bash

echo "Type the username, followed by [ENTER]:"

read usrname

echo "The name entered was: $usrname"

更新

#!/bin/bash

echo "Type the username, followed by [ENTER]:"

read usrname

echo "Type the path, followed by [ENTER]:"

read pthname

echo "The name entered was: $usrname"
echo "The path entered was: $pthname"

if [ -d "$pthname" ]
then
  echo "$pthname is a directory."
  expdp  system/manager content=ALL directory=$pthname dumpfile=expdp_`echo $ORACLE_SID`_%U_`echo $DATEFORMAT`.dmp full=Y logfile=$EXPLOG
fi

更新2

谢谢，我想保存导出路径到用户指定的路径请提供任何帮助您的意思是：

导出路径=“$path:$username”

当我运行脚本时，它应该请求路径存储导出转储，并使用该路径存储文件oh，您可以用完全相同的方式读取它：

read inputpath

在oracle expdp中，我们使用在数据库中创建一个单独的目录和路径，在获取导出转储时，它使用该目录路径并将转储文件保存到该路径。现在我想将转储文件保存到用户指定的路径。您需要在没有提示的情况下自动获取？如果是，您可以使用

expect

从shell提示符获取字符串。您可以向我们展示该行的工作版本，就像从命令行中键入的那样：expdp syst…expdp system/manager content=ALL directory=expdir dumpfile=expdp\code>echo$ORACLE\U SIDecho$DATEFORMAT.dmp full=Y日志文件=$EXPLOG

You can use Without Security :
echo "User name: $0"
echo "Password: $1"

You can use With Security :
read -s -p "Password: " password

$ help read
read: read [-ers] [-a array] [-d delim] [-i text] [-n nchars] [-N nchars] [-p prompt] [-t timeout] [-u fd] [name ...]
Read a line from the standard input and split it into fields.
  ...
  -p prompt output the string PROMPT without a trailing newline before
