Question

我试图用这种方式读取两个文件：

if [[ $COPY_PREV_DEPLOYMENT == true ]]; then
    echo [$JOB_NAME] Copying old environment variables of $OLD_APP app to the new environment variables of $NEW_APP app...
    cf env $NEW_APP | awk '/User-Provided/,/No staging env variables have been set/'| cut -f1 -d":" | tail -n +2 > env_variables.txt
    cf env $OLD_APP | awk '/User-Provided/,/No staging env variables have been set/'| cut -f2 -d":" | tail -n +2 > env_variables_values.txt
    paste env_variables.txt env_variables_values.txt | while read -r VARIABLE VALUE
    do
        cf set-env "$NEW_APP" "$VARIABLE" "$VALUE"
    done 
    echo [$JOB_NAME] Done.
fi

但我正面临这个问题

..... sh：第61行：意外令牌do' ......sh: line 61:附近的语法错误（'

有人可以帮我解决吗？

非常感谢

在do条件之后，您不会使用if。 do... done主要用于loops。此外，似乎不需要括号来从cloudfoundry api包装此单个执行语句。

代码可能如下所示：

if [[ $COPY_PREV_DEPLOYMENT == true ]]; then
    echo $JOB_NAME Copying old environment variables of $OLD_APP app to the new environment variables of $NEW_APP app...
    cf env $NEW_APP | awk '/User-Provided/,/No staging env variables have been set/'| cut -f1 -d":" | tail -n +2 > env_variables.txt
    cf env $OLD_APP | awk '/User-Provided/,/No staging env variables have been set/'| cut -f2 -d":" | tail -n +2 > env_variables_values.txt
    paste env_variables.txt env_variables_values.txt | while read -r VARIABLE VALUE; do 
        cf set-env "$NEW_APP" "$VARIABLE" "$VALUE"
        done
    echo $JOB_NAME Done.
fi

如何解决错误：意外令牌附近的语法错误`do'
