bash命令跨越多行，中间有几行注释

Question

  

可能重复：
  Bash: How to Put Line Comment for a Multi-line Command

我想做这样的事情

sudo apt-get install \
  #a very long description
  #of the package
  #that spans multiple lines
  pkg1 \ #maybe I want an inline comment also
  #another description that
  #spans multiple lines
  pkg2

请注意，我不仅对apt-get命令感兴趣。

据我所知，Bash在单个命令中忽略了'＃'之后的所有内容，而且多线程不会改变它。但是，您可以使用bash数组实现相同级别的表达式：

packagelist=(
  package1 # Inline Comments
  # Multiline Comments too
  package2
  # Package description goes here
  # Detailed descriptions..
)
sudo apt-get install ${packagelist[@]}
