本文整理了Java中org.apache.hadoop.util.Shell.bashQuote()方法的一些代码示例，展示了Shell.bashQuote()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Shell.bashQuote()方法的具体详情如下：
包路径：org.apache.hadoop.util.Shell
类名称：Shell
方法名：bashQuote
[英]Quote the given arg so that bash will interpret it as a single value. Note that this quotes it for one level of bash, if you are passing it into a badly written shell script, you need to fix your shell script.
[中]引用给定的arg，以便bash将其解释为单个值。请注意，这引用了一个级别的bash，如果要将其传递到一个写得不好的shell脚本中，则需要修复shell脚本。
