linux - 如何将这个 bash 脚本移植到 sh？

Question

这个有效:

#!/bin/bash
while read system_name mount_name
do
   echo "${system_name} ${mount_name}"
done < <(echo "select system_name, mount_name from SystemTable" | mysql ifm -uroot -pinsite3)

但是如果我将 shebang 变量更改为 #!/bin/sh 则不会这样如何使上述脚本在 sh shell 中运行？

Answer 1

也许:

#!/bin/sh

echo "select system_name, mount_name from SystemTable" | mysql ifm -uroot -pinsite3 |
while read system_name mount_name
do
   echo "${system_name} ${mount_name}"
done
