Question

我要寻找的是在Linux中将一个命令的输出用作“完全相同的其他命令”？

例如：

[root@ip-10-0-0-136 ~]# echo hi
hi
[root@ip-10-0-0-136 ~]

现在我要将此“ hi”用作立即命令并执行。我怎样才能做到这一点？

因此，应类似于：

[root@ip-10-0-0-136 ~]# echo hi
hi
[root@ip-10-0-0-136 ~]# hi

有可能吗？

请提出建议

[root@ip-10-0-0-136 ~]# aws ecr get-login --no-include-email --region eu-central-1

Answer 1

您可以使用命令替换：

[root@ip-10-0-0-136 ~]# $(echo hi)

与

相同

[root@ip-10-0-0-136 ~]# `echo hi`

Answer 2

您可以使用$(aws ecr get-login --no-include-email --region eu-central-1) 这将在括号中执行命令的输出。在您的情况下，命令docker login -u AWS -p eyJwYX..将被执行

Answer 3

是的，可以使用!$。如果我使用[root@ip~ppp]$ echo cd cd [root@ip~ppp]$ !$ cd [root@ip~]$

执行cd命令

Answer 4

我认为您可以简单地通过管道传输一些输出并将其提供给bash命令。

echo 'ls' | bash

如何在Linux中将一个命令的输出用作另一个命令
