是否可以在shell脚本的多行命令中包含内联注释?
我知道我可以在 bash 中使用分隔长命令- 有没有办法编写内联注释?
例如,类似于:
wget
# Needed to get to end of around 100 pages of results
--level=0
# Save into downloads directory
--directory=downloads
--recursive
# Normally wget won't span hosts, and .example.com use a CDN
--span-hosts --domains='assets.publishing.example.com,www.example.com'
# Only care about links matching this regex
--accept-regex 'assets|swag' --regex-type pcre
# The site we actually want to scrape
'https://www.example.com/swag'
如果可以使用zsh pwsh或类似,我也很感兴趣。

不是直接的,但您可以将参数存储在多行定义的数组中,并且可以在这些行之间添加注释。
wget_args=(
# Needed to get to end of around 100 pages of results
--level=0
# Save into downloads directory
--directory=downloads
--recursive
# Normally wget won't span hosts, and .example.com use a CDN
--span-hosts --domains='assets.publishing.example.com,www.example.com'
# Only care about links matching this regex
--accept-regex 'assets|swag' --regex-type pcre
# The site we actually want to scrape
'https://www.example.com/swag'
)
wget "${wget_args[@]}"
