Re: Feature request for PS0

[Alex fxmbsw7 Ratchev]

PS0=$'\e[1A\e[K$time \e[s\n' PS1=$'prompt] ' PROMPT_COMMAND='printf -v
time "%(%F-%T)T" ${EPOCHREALTIME%.*}' ; trap $'[[ $BASH_COMMAND !=
@(trap|"printf -v time ")* ]] && { cmd=$BASH_COMMAND; IFS=$\'[;\' read
-r -d R -p $\'\\e[6n\' none line char ; printf \'\\e[u%s\e[%d;%dH\'
"$cmd" "$line" "$char" ; }' debug

but, there are two issues
one after setting a garbage command may be disabled, if no cmd was
prevously entered all ok may appear

then looked good

2022-02-08-03:35:29 ls
bl5  bl5e  bl5.tgz  t  xbl5  xbl5.750763197  xbl5e  xbl5e.3881483953
xbl5.tgz  xft  xft.tgz
2022-02-08-03:35:35 ps
  PID TTY          TIME CMD
  224 pts/2    00:00:00 bash
  328 pts/2    00:00:00 bash
  388 pts/2    00:00:00 bash
  631 pts/2    00:00:00 ps

but on piped commands, along sometimes else i think i saw, i get:

2022-02-08-03:35:39 head -1
^[[16;1Rbl5 read error: 0: Input/output error
prompt] ;1R
