在Linux下，使用c ++中的system（）执行命令的转义序列

Question

I want to execute a command using system() . The command needs a file name as a parameter. Something like this:

void f(string filename){
  strnig cmd = "path/to/my/command " + filename; 
  system(cmd.c_str());
  ... 
}

My question is what escape sequences could I use so that the string received in filename will be considered just the name of the file and nothing more. For example, if filename = "aname;rm *" , I don't want my command to be executed on "aname" and then "rm *" to be considered a new command and to delete everything from my current directory.

Also, I wish that my filename to be able to contain special characters like: ' , " or space, without affecting the command execution.

How do I do this in c++?

Thank you!

Answer 1

man system:

system() executes a command specified in command by calling /bin/sh -c command

so use the escape sequences your shell honors.
