bash - Oracle expdp CentOS 6.2 Shell 脚本异常行为 - 换行给出未找到的命令

Question

我的第一篇文章是温柔的。

我有下面的脚本，它是从 RedHat 5.3 盒子中取出来备份 Oracle 数据库的。该脚本在 Redhat 5.3 机器上运行良好。然后，我将其用作在 centos 6.2 机器上备份 oracle 数据库的引用，并根据需要对其进行了修改。

#!/bin/bash
ORACLE_HOME="/u01/app/oracle/product/11.2.0/db_1"
NLS_LANG=AMERICAN_AMERICA.AR8ISO8859P6

BKDATE=`date "+%Y-%m-%d_%H-%M-%S"`
C1="system/password@dbname DIRECTORY=RMBACKUP SCHEMAS=USER1,USER2,USER3 DUMPFILE=dbname_"
C2="_full_pump.dmp LOGFILE=dbname_"
C3="_full_pump.log"
BKCMD=$C1$BKDATE$C2$BKDATE$C3
echo $C1
echo $C2
echo $C3
echo $BKDATE
echo $BKCMD
#run the exp backup
$ORACLE_HOME/bin/expdp $BKCMD

奇怪的行为是，当我执行脚本时，新行导致命令未找到错误，并且连接被合并，如下所示。

system/password@dbname DIRECTORY=RMBACKUP SCHEMAS=USER1,USER2,USER3 DUMPFILE=dbname_
_full_pump.dmp LOGFILE=dbname_
_full_pump.log
2012-07-10_09-39-06
system/password@dbname DIRECTORY=RMBACKUP SCHEMAS=USER1,USER2,USER3 DUMPFI_full_pump.log39-06ILE=dbname_
/bin/expdp: No such file or directoryacle/product/11.2.0/db_1

与其他文本合并的日期不是拼写错误，那是回显输出。

我在开头添加了 set -x，这是输出

+ NLS_LANG=$'AMERICAN_AMERICA.AR8ISO8859P6\r'

如您所见，文本中有'\r' 个字符。可能您使用在行尾自动添加 \r 的编辑器编辑了文件。您必须再次编辑该文件并删除这些字符。
