我要使用bash从快照请求中提取与变量名关联的元数据。下面的代码可以工作，除了两个问题：
第一个问题是描述信息的提取不完整。它在说明中的两个空白行之后停止。
第二个问题是，除了快照ID之外，它无法获取描述字段之后的其余字段。
代码：
Package=telegram-desktop
Package_Info=Package_Info.txt
snap info --verbose $Package > $Package_Info # Store to avoid multiple fetches from Internet
Snap_name=`cat $Package_Info | awk '/:/{f=/^name/}f' | sed 's/: */:/g' | cut -d ":" -f 2`
Snap_summary=`cat $Package_Info | awk '/:/{f=/^summary/}f' | sed 's/: */:/g' | cut -d ":" -f 2`
Snap_publisher=`cat $Package_Info | awk '/:/{f=/^publisher/}f' | sed 's/: */:/g' | cut -d ":" -f 2`
Snap_contact=`cat $Package_Info | awk '/:/{f=/^contact/}f' | sed 's/: */:/g' | cut -d ":" -f 2-3`
Snap_license=`cat $Package_Info | awk '/:/{f=/^license/}f' | sed 's/: */:/g' | cut -d ":" -f 2`
Snap_description=`cat $Package_Info | awk '/:/{f=/^description/}f' | sed 's/: */:/g' | cut -d ":" -f 2`
Snap_notes=`cat $Package_Info | awk '/:/{f=/^notes/}f' | sed 's/: */:/g' | cut -d ":" -f 2`
Snap_snap_id=`cat $Package_Info | awk '/:/{f=/^snap-id/}f' | sed 's/: */:/g' | cut -d ":" -f 2`
Snap_channels=`cat $Package_Info | awk '/:/{f=/^channels/}f' | sed 's/: */:/g' | cut -d ":" -f 2`
printf "$Snap_name\n$Snap_summary\n$Snap_publisher\n$Snap_contact\n$Snap_license\n$Snap_description\n$Snap_notes\n$Snap_snap_id\n$Snap_channels\n"

Pure instant messaging — simple, fast, secure, and synced across all your
devices. Over 100 million active users in two and a half years.
FAST: Telegram is the fastest messaging app on the market, connecting
people via a unique, distributed network of data centers around the globe.
SYNCED: You can access your messages from all your devices at once. Start
typing on your phone and finish the message from your tablet or laptop.
Never lose your data again.
UNLIMITED: You can send media and files, without any limits on their type
and size. Your entire chat history will require no disk space on your
device, and will be securely stored in the Telegram cloud for as long as
you need it.
SECURE: We made it our mission to provide the best security combined with
ease of use. Everything on Telegram, including chats, groups, media, etc.
is encrypted using a combination of 256-bit symmetric AES encryption,
2048-bit RSA encryption, and Diffie–Hellman secure key exchange.
POWERFUL: You can create group chats for up to 100,000 members, share large
videos, documents of any type (.DOC, .MP3, .ZIP, etc.), and even set up
bots for specific tasks. It's the perfect tool for hosting online
communities and coordinating teamwork.
RELIABLE: Built to deliver your messages in the minimum bytes possible,
Telegram is the most reliable messaging system ever made. It works even on
the weakest mobile connections.
FUN: Telegram has powerful photo and video editing tools and an open
sticker/GIF platform to cater to all your expressive needs.
SIMPLE: While providing an unprecedented array of features, we are taking
great care to keep the interface clean. With its minimalist design,
Telegram is lean and easy to use.
100% FREE & NO ADS: Telegram is free and will always be free. We are not
going to sell ads or introduce subscription fees.
PRIVATE: We take your privacy seriously and will never give third parties
access to your data.
We keep expanding the boundaries of what you can do with a messaging app.
Don’t wait years for older messengers to catch up with Telegram — join the
revolution today.
