Golang:带有->字符的命令行参数

I need to accept command line argument to run a Go program in the below format:

 go run app.go 1->A

I am using os.Args[1]. But it only accepts till '1-' . '>A' is being skipped.

Any help to resolve this issue is highly appreciated.

Thanks

    Your shell is interpreting the > as IO redirection. The shell opened the file A as standard output for the command and passed the argument 1- to the command.

    Quote the argument to avoid this:

    go run app.go "1->A"
