How to escape an @ sign in the password field of an smb:// URL
提问by codersarepeople
I'm trying to write a bash script in which I connect to a samba server, by getting the username and password, then saying $username:$password@SERVERNAME.
我正在尝试编写一个 bash 脚本，在其中连接到 samba 服务器，获取用户名和密码，然后说 $username:$password@SERVERNAME。
However, this will fail if the password has an @ in it. Is there a way to escape the @ out of the password in bash?
但是，如果密码中有@，这将失败。有没有办法在bash中将@从密码中转义出来？
Thanks in advance
提前致谢
Update: I'm setting up this network printer
更新：我正在设置这台网络打印机
lpadmin -p PRINTER -v smb://$username:$password@SERVER -E
and it works except in the case that $password has an @ sign in it; the $username and $passwords variables are gotten from reading stdin
它可以工作，除非 $password 中有 @ 符号；$username 和 $passwords 变量是通过读取标准输入获得的

Ah, no, this isn't actually a matter of quoting for Bash, but quoting for Samba. You have this:
啊，不，这实际上不是为 Bash 引用的问题，而是为 Samba 引用的问题。你有这个：
lpadmin -p PRINTER -v smb://$username:$password@SERVER -E
which Bash dutifully expands to
Bash 尽职尽责地扩展到
lpadmin -p PRINTER -v smb://alice:passw@rd@SERVER -E
and then the Samba client librarythinks the password ends at the first @ sign and it's supposed to connect to a server named rd@server, never mind that you can't actually put that name in the DNS.
然后Samba 客户端库认为密码以第一个 @ 符号结尾，并且它应该连接到名为 的服务器rd@server，别介意您实际上不能将该名称放入 DNS 中。
lpadmincomes from CUPS, not from Samba (here is its manpage) and, reading through those docs a bit, I think you may be able to use this alternate syntax:
lpadmin来自 CUPS，而不是来自 Samba（这是它的手册页），并且稍微通读一下这些文档，我认为您可以使用以下替代语法：
lpadmin -p PRINTER -U "${username}%${password}" -v smb://SERVER -E
I'm surprised escaping @as %40doesn't work, though. Looks like a bug in the samba client library to me.
不过，我很惊讶逃避@是%40行不通的。对我来说看起来像是 samba 客户端库中的一个错误。

I use the cups admin at http://localhost:631/to add printers. Encoding @ as %40 worked for me.
我使用http://localhost:631/上的 cups admin添加打印机。将@ 编码为 %40 对我有用。
