在 while 循环中调用时，Shell 脚本将无法正确运行

Question

以下 shell 脚本读取文件，但在执行 esscs.sh 时返回错误：

Error: Could not find or load main class a

cd /u01/oracle/essbase/products/Essbase/EssbaseServer/bin/cli/
while read application; do
        if [[ $application = "" || $application = "#"* ]]
        then
                continue
        else
                ./esscs.sh login -user usr -password xxx -essbaseurl https://bla/essbase
                ./esscs.sh lcmexport -application $application
        fi
done < /tmp/exportLCM_applications.txt

以下 shell 脚本运行良好：

cd /u01/oracle/essbase/products/Essbase/EssbaseServer/bin/cli/
./esscs.sh login -user usr -password xxx -essbaseurl https://bla/essbase
./esscs.sh lcmexport -application hardcodedapp

这是 esscs.sh 的内容，它是 Essbase (cli) 的 Oracle 命令行实用程序：

#!/bin/sh

export ERR_MSG_JAVA_REQUIRED="Install JDK8 and set JAVA_HOME variable to JDK8 installed location"

if [ -z "$JAVA_HOME" ]
then
    echo
    echo $ERR_MSG_JAVA_REQUIRED
    echo
    exit 1
fi

export JAVA_VERSION=$("$JAVA_HOME/bin/java" -version 2>&1 | awk -F '"' '/version/ {print $2}')

if [[ "$JAVA_VERSION" < "1.8" ]]
then
    echo
    echo You are using older java version $JAVA_VERSION
    echo $ERR_MSG_JAVA_REQUIRED
    echo
    exit 1
fi

我通过阅读文档解决了这个问题：

要执行多个 CLI 命令，请将它们添加到任何 shell 脚本中并 执行它。在您运行的任何包含 CLI 命令的脚本中，Oracle 建议您在 CLI 登录之前包含以下指令 语句： 对于 Windows：设置 ESSCLI_ID=%USERNAME%%random% 对于 Linux： export ESSCLI_ID=

whoami

$PPID 这有助于存储会话信息 并防止运行多个脚本时出现执行错误 同时。
