剧本：
thufir@dur:~$
thufir@dur:~$ cat powershell/weather/b.sh
#!/usr/bin/pwsh -Command
echo "hello world"
"done"
thufir@dur:~$
难道不是吗可能的使其成为可执行脚本？也许这不是正确的第一行？
详细信息powershell：
thufir@dur:~$

哎呀：
$
$ cat powershell/weather/c.ps1
#!/usr/bin/pwsh -Command
echo "hello world"
"done"
$ ./powershell/weather/c.ps1
hello world
done
$
它只是必须有.ps1文件扩展名。Microsoft。
