Bash：如何为多行命令添加行注释
I would like to do something like this
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
Note that I'm not just interested in the apt-getcommand.
请注意，我不仅对apt-get命令感兴趣。

As far as I know Bash ignores everything after the '#' in a single command, and multilining won't change that. However you can probably achieve the same level of expression using bash arrays:
据我所知，Bash 在单个命令中忽略 '#' 之后的所有内容，并且多行不会改变这一点。但是，您可能可以使用 bash 数组实现相同级别的表达：
packagelist=(
package1 # Inline Comments
# Multiline Comments too
package2
# Package description goes here
# Detailed descriptions..
)
sudo apt-get install ${packagelist[@]}
