我一直在嘗試運行一個命令，以便不必使用 bash 腳本，而是使用 go 來運行命令。HOME=/home/gogopowerrangers 在 ubuntu 18.04 上const systemInfoLoc string = "$HOME/systemvar.txt"//I've tried to run with full path as well heregetSystemKernel := exec.Command("uname", "-s", ">>", "home/username/system.txt")getSystemKernel.Run()//^doesn't seem to return anything//orgetsystemvar,_ = exec.Command("echo", "$USER", ">", "$HOME/systemvar.txt").Outputfmt.Println(string(getsystemvar))//here even after the system doesn't seen to recognize $USER or $HOME or actually get the variables我的語法錯誤嗎？我可以將參數(shù)作為 args []string 傳遞，但這似乎沒有什么區(qū)別。我知道如果我將它們寫入 CMD 行或 bash 腳本中它們會起作用。如果您發(fā)現(xiàn)有問題，請告訴我。
