Right, the original linenoise ignore ctrl-z. There is another
fork that seemed has a patch for it.
case ctrl('Z'): /* ctrl-z */
#ifdef SIGTSTP
/* send ourselves SIGSUSP */
disableRawMode(current);
raise(SIGTSTP);
/* and resume */
enableRawMode(current);
refreshLine(current);
#endif
continue;
If users want the same level of functions of libedit, the
linenoise version can never satisfy them no matter how hard
we put efforts to improve linenoise. It is better to use the
libedit in that case.
