Question on bash command line
OS : RHEL / Oracle Linux 6.8
In bash shell, how can I replace a character under the cursor with another character ?
In the below example , after I typed the following line, I realized that I meant 7013 and not 2013. So I move the cursor to the left and keep it on top of 2 (of 2013) and I want to replace 2 with 7. How can I do that ?
$ echo hello world 2013
This question is
not about replacing characters within vi/vim/emacs
A video example (for more clarity)
In the below video, how is this guy changing 2010 to 2011 instantly ? He also changes 2011 to 2012 , ... etc . I tried googling and I couldn't find anything on this. Hence posting it here.

posix2oracle
Takes a "strftime" or "strptime" formatting string and converts it into an Oracle NLS_DATE_FORMAT string. It is possible to create
strings which Oracle will not accept as valid NLS_DATE_FORMAT strings.
my $format = posix2oracle('%Y-%m-%d %H:%M:%S'); # 'YYYY-MM-DD HH24:MI:SS'
