Bash - How to pass arguments to a script that is read via redirected standard input
提问by dabest1
I would like to expand a little more on "Bash - How to pass arguments to a script that is read via standard input" post.
我想对“ Bash - 如何将参数传递给通过标准输入读取的脚本”一文进行更多的扩展。
I would like to create a script that takes standard input and runs it remotely while passing arguments to it.
我想创建一个脚本，它接受标准输入并在向它传递参数的同时远程运行它。
Simplified contents of the script that I'm building:
我正在构建的脚本的简化内容：
ssh server_name bash <&0
How do I take the following method of accepting arguments and apply it to my script?
如何采用以下接受参数的方法并将其应用于我的脚本？
cat script.sh | bash /dev/stdin arguments
Maybe I am doing this incorrectly, please provide alternate solutions as well.
也许我这样做不正确，也请提供替代解决方案。

sshshouldn't make a difference:
ssh应该没有区别：
$ cat do_x
#!/bin/sh
arg1=
arg2=
all_cmdline=$*
read arg2_from_stdin
echo "arg1: ${arg1}"
echo "arg2: ${arg2}"
echo "all_cmdline: ${all_cmdline}"
echo "arg2_from_stdin: ${arg2_from_stdin}"
$ echo 'a b c' > some_file
$ ./do_x 1 2 3 4 5 < some_file
arg1: 1
arg2: 2
all_cmdline: 1 2 3 4 5
arg2_from_stdin: a b c
$ ssh some-server do_x 1 2 3 4 5 < some_file
arg1: 1
arg2: 2
all_cmdline: 1 2 3 4 5
arg2_from_stdin: a b c
