frist press esc to go out of insert mode. then you text :wq (command used to save and exit), if you wanna exit without save you text :q, and if you wanna just save text :w

//current process status
int
cps()
{
struct proc *p;
// Enable interrupts on this processor.
sti();
// Loop over process table looking for process with pid.
acquire(&ptable.lock);
cprintf("name \t pid \t state \t
");
for(p = ptable.proc; p < &ptable.proc[NPROC]; p++){
if (p->state == SLEEPING)
cprintf("%s \t %d \t SLEEPING \t
", p->name, p->pid);
else if (p->state == RUNNING)
cprintf("%s \t %d \t RUNNING \t
", p->name, p->pid);
else if (p->state == RUNNABLE)
cprintf("%s \t %d \t RUNNABLE \t
