Cursor Movement in bash: either echo escape sequences or use tput

Posted by jpluimers on 2020/06/03

I read [WayBackCursor Movement earlier than [WayBack] Colours and Cursor Movement With tput and [WayBack] The Floating Clock Prompt.

So in one of my scripts I’ve now used an escape sequence, but I might change it to tput in a future version:

## Move one line up, then write finished scripts:
echo -e "\033[1A$finished\r"

I would probably have started with put if I had read [WayBack] bash – Set or change vertical position of the cursor – Stack Overflow first.

How do I delete a Bash function? – Stack Overflow

Posted by jpluimers on 2020/06/02

I hardly do this, so I tend to forget that unset -f functionname deletes a function and unset variablename or unset -v variablename deletes a variable.

From:

I have done this:bash $ z() { echo ‘hello world’; }How do I get rid of it?
