寻找匹配的 '"' 时出现意外的 EOF - bash 脚本

我刚刚编写了一个 bash 脚本，但总是收到此 EOF 错误。

这是我的脚本（仅适用于 OS X）：

#!/bin/bash

#DEFINITIONS BEGIN
en_sq() {
    echo -e "Enabling smart quotes..."
    defaults write NSGlobalDomain NSAutomaticQuoteSubstitutionEnabled -bool true
    status=$(defaults read NSGlobalDomain NSAutomaticQuoteSubstitutionEnabled -bool)
            if [ "$status" = "1" ]
                then
                    echo -e "Success! Smart quotes are now enabled."
                    SUCCESS="TRUE"
            else
                echo -e "Sorry, an error occured. Try again."
            fi
}
di_sq() {
    echo -e "Disabling smart quotes..."
    defaults write NSGlobalDomain NSAutomaticQuoteSubstitutionEnabled -bool false
    status=$(defaults read NSGlobalDomain NSAutomaticQuoteSubstitutionEnabled -bool)
            if [ "$status" = "0" ]
                then
                    echo -e "Success! Smart quotes are now disabled."
                    SUCCESS="TRUE"
            else
                echo -e "Sorry, an error occured. Try again."
            fi
}
en_sd() {
    echo -e "Enabling smart dashes..."
    defaults write NSGlobalDomain NSAutomaticDashSubstitutionEnabled -bool true
    status=$(defaults read NSGlobalDomain NSAutomaticDashSubstitutionEnabled -bool)
            if [ "$status" = "1" ]
                then
                    echo -e "Success! Smart dashes are now enabled."
                    SUCCESS="TRUE"
            else
                echo -e "Sorry, an error occured. Try again."
            fi
}
di_sd() {
    echo -e "Enabling smart dashes..."
    defaults write NSGlobalDomain NSAutomaticDashSubstitutionEnabled -bool false
    status=$(defaults read NSGlobalDomain NSAutomaticDashSubstitutionEnabled -bool)
            if [ "$status" = "0" ]
                then
                    echo -e "Success! Smart dashes are now disabled."
                    SUCCESS="TRUE"
            else
                echo -e "Sorry, an error occured. Try again."
            fi
}

这是我的错误：

./coding.sh: line 144: unexpected EOF while looking for matching `"'
./coding.sh: line 147: syntax error: unexpected end of file

只要你看一下你的问题，你就可以看到你的问题。注意第 95 行之后语法高亮是如何混乱的：

echo -e "Sorry, an error occurred. You have to run this on OS X""

正如错误消息告诉您的那样，您有一个不匹配的".只需"从上面的行中删除多余的内容就可以了：

echo -e "Sorry, an error occurred. You have to run this on OS X"

在实际情况下，此错误可能很难跟踪。在这里，我为现实情况提供了一种解决方案。我将使用我的脚本作为示例。

我更新了我的 shell 脚本。执行时我收到以下错误消息：

/somepath/bin/myshellscript: line 1508: unexpected EOF while looking for matching `"'
/somepath/bin/myshellscript: line 1520: syntax error: unexpected end of file

line 1508 elif [ "$project" ]; then

这是带有一对双引号的最后一行。

通常，我每次修改 shell 脚本时都会检查它。这次等了一天，忘记在哪里修改了。问题发生在该行 (1508) 之前的任何位置。问题是连我都评论了大纲1508

#elif [ "$project" ]; then

shell 执行者仍然说第 1508 行有问题。

接下来，我复制了原始 shell 脚本。从底部删除一大堆代码。然后使用以下命令验证我的代码

bash -n mysbashscript

mybashscript: line 515: unexpected EOF while looking for matching `"'
mybashscript: line 561: syntax error: unexpected end of file

现在我的文件大小是原始大小的 1/3。我立即看到了问题：

497 prepare_alignment() {
498     local projdir=${1:?"did not give project directory"}
499     local samp=${2:?"did not give sample name"}
500     local merged=${3:?"must give merged bam file name} # here is the problem

由于某种原因，shell解析器没有捕获到"内部不匹配的内容。{}这是 shell 解析器可以进一步改进的地方。

找到问题最快的算法是从底部删除一半的代码，如果语法错误消失，那么它就在这一半中。如果语法错误仍然存​​在，则问题出在上半部分。

如果后半部分出现问题，则撤消删除。重复此过程。您可以缩小范围以找到问题的根源。

删除代码时，必须删除整段代码。例如整个功能。

您可以使用 bash-n script_name或直接执行脚本。两者都应该有效。 （这里 script_name 只是用于说明目的的 fooscript 或 barscript，而不是真正的脚本名称，应该是一个单词）。

由于缺少大括号，我遇到了此错误...

docker tag "${FOO" "${BOO}"

答案4

另一件需要考虑的事情是，一些关键字符开始一个块，双引号可能不是问题。我将 bash 中的所有变量用大括号括起来，但是如果您不小心使用方括号而不是大括号，则会弹出此错误，并且引号都会令人沮丧地排列起来。使用Kemin Zhou的流程，我能够找到这个错字。 echo "Starting $[report_name}" >> ${log}看起来很像echo "Starting ${report_name}" >> ${log}。双引号不是问题，但据报道是这样的。
