我正在编写一个bash脚本，如果用户的AWS密钥已过期，它将向用户发送电子邮件。我想包含一个指向Service Now票证的可单击链接，他们可以使用这些链接来旋转其AWS密钥。
这是脚本的一部分，用于设置电子邮件的文本：
fusion_link='<a href="https://company.service-now.com/myfusion?id=sc_cat_item&sys_id=7949c77e6ffc310048c83cb44b3ee4a7">Change AWS Configuration</a>'
template1="Hello $first_name, \n\nYour access key: $user_access_key1 for user name: $user_name was created on $date1 and needs to be replaced.\n\nThis key is in AWS Account: $aws_key ($accountnumber).\n\nPlease open up a fusion ticket using this catalog item: $fusion_link to have Cloud Ops rotate your keys.\n\nAll AWS Keys need to be replaced if they are older than 90 days.\n\nRegards,\nCloud Ops"
但是当电子邮件到达Outlook（打开HTML）时，这就是我得到的输出。链接未形成，因此用户可以单击它：
Hello Tim,
Your access key: AKIAI7EYXZMWBBAOLYJA for user name: tdunphy was created on Thu Jan 4 16:03:32 EST 2018 and needs to be replaced.
This key is in AWS Account: company-ab-nonprod (151528745488).
Please open up a fusion ticket using this catalog item: <a href="https://company.service-now.com/myfusion?id=sc_cat_item&sys_id=7949c77e6ffc310048c83cb44b3ee4a7">Change AWS Configuration</a> to have Cloud Ops rotate your keys.
All AWS Keys need to be replaced if they are older than 90 days.
Regards,
Cloud Ops
我正在使用以下行在bash脚本中发送电子邮件：
echo -e "$template1" | /usr/bin/mail -s "AWS Key Rotation Needed for $user_name in $aws_key" "$email_address"
电子邮件中有锚标记，但不可单击。如何正确设置链接的格式，以便用户单击它？
