Use the getchar() function.

void pause(const string msg = "Press enter/return to 
continue...")

{
write(msg);
getchar();
}


just call std.stdio.stdin.read() and ignore the result...

void writeAndPause(string s)
{
writeln(s);
// writeln("Press any key to continue...");  // works fine on 
Windows
// executeShell("pause");// works fine on 
Windows


I tried the following read command and it works great in a Ubuntu 
shell:

read -rsp $'Press any key to continue...\n' -n 1 key

but when I put it in executeShell it doesn't pause and returns

executeShell(`read -rsp $'Press any key to continue...\n' -n 1 
key`);
executeShell("read -rsp $'Press any key to continue...\n' -n 1 
key");


returns /bin/sh: 1: read: Illegal option -s


I tried the spawnShell...

auto pid = spawnShell(`read -n1 -r -p "Press any key to 
continue..." key`);

wait(pid);

 returns  /bin/sh: 1: read: Illegal option -n
}
