Following up on my previous TIL post about
iex, I learned today that I didn’t understand control characters in my shell at all. Running
stty -a shows my current shell settings:
$ stty -a ... cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>; eol2 = <undef>; erase = ^?; intr = ^C; kill = ^U; lnext = ^V; min = 1; quit = ^\; reprint = ^R; start = ^Q; status = ^T; stop = ^@; susp = ^Z; time = 0; werase = ^W;
Control + backslash is right there, labelled as “quit” meaning it will send
SIGQUIT to the foreground process. Super handy.
