如何在Bash中的Heredoc之后设置参数

Question

I'd like to modify the following script to

tmp=$(cat <<'EOT'
ssh user@sv7247.xserver.jp
EOT
)
expecto "${tmp}" "${PASSWORD}"

like following script because just I want to make short the script.

expecto "$(cat <<'EOT' "${PASSWORD}"
ssh user@sv7247.xserver.jp
EOT
)"

However the shorted script not work. It is seems to caused by the second argment "${PASSWORD}" is not recognized.

How is the corrent way to do that thing?

Answer 1

You would write:

expecto "$(cat <<'EOT'
ssh user@sv7247.xserver.jp
EOT
)" "${PASSWORD}"

Your readability is really suffering there. I would think twice about cramming that all together.
