How to spawn a process

spawn_process.zig

const std = @import("std");
const Child = std.process.Child;
const ArrayList = std.ArrayList;

pub fn main() !void {
    var gpa = std.heap.GeneralPurposeAllocator(.{}){};
    const allocator = gpa.allocator();
    defer {
        const deinit_status = gpa.deinit();
        _ = deinit_status;
    }
    // var stdout_buf = ArrayList(u8).init(allocator);
    // defer stdout_buf.deinit();
    // var err_buf = ArrayList(u8).init(allocator);
    // defer err_buf.deinit();
    const command = [_][]const u8{ "ls", "-la" };

    var child = Child.init(&command, allocator);
    try child.spawn();
    // try child.collectOutput(&stdout_buf, &err_buf, 0x1000);
    const res = try child.wait();

    std.debug.print("{!}\n", .{res});
    // std.debug.print("stdout: {s}\nerr: {s}\n", .{ stdout_buf.items, err_buf.items });
}
