在 shell 脚本中将 eval 变量作为命令

Question

我有命令

docker container exec -it man docker service ps $1 --no-trunc --filter "desired-state=running" --format "docker container exec -it {{.Node}} docker container exec -it {{.Name}}.{{.ID}} bash"

它在 stdout 中返回如下字符串

docker container exec -it 13247a1833e9 docker container exec -it django_python.yhb1osnt1wn32hbkixhf50r38.hzsgyxbdkpitrsa6fdjiyi4qu bash

现在我想执行这个。

我的脚本在这里，

msg=`docker container exec -it man docker service ps $1 --no-trunc --filter "desired-state=running" --format "docker container exec -it {{.Node}} docker container exec -it {{.Name}}.{{.ID}} bash"`

eval ${msg}

但它返回错误

OCI runtime exec failed: exec failed: container_linux.go:348: starting container process caused "exec: \"bash\\r\": executable file not found in $PATH": unknown

我该如何解决这个问题？
