The above table shows that Esc[2K
clears a line.
But on Mac Terminal, I don't see the line is cleard.
$ echo abc$'\e[2k'
abc
The TERM variable is the following.
$ declare -p TERM
declare -x TERM="xterm-256color"
Does anybody how to clear a line? (If possible, it should work on other terminals as well other than Mac Terminal.) Thanks.

I would just wager it as minor typo, because the escape sequence associated with clearing a line is Esc[2K
with an upper case K
and not k
echo -e abc$'\e[2K'
should work just as expected. Note that echo -e
and the ANSI C style escapes ($'...'
) are bash
shell specific and non POSIX conformant. You can always use printf()
that supports escape sequences too
printf abc'\e[2K'
Also the escape character notation \e
may not be supported in all versions of echo
, but the only the bash
built-in provided. You could use the hex equivalent of \e
as \x1B
or an octal equivalent of \033
.
