Function exec_cmd

pub fn exec_cmd(cmd: &str)
Expand description

Executes an external command and waits for it to complete.

The command’s output goes to stdout (i.e., not captured). Similar to Python’s os.system("something").

The command must be a simple command with some optional arguments. Pipes, redirections are not allowed.

§Examples

let cmd = "rustc --version";
jabba_lib::jprocess::exec_cmd(cmd);
