Re: enhancement merge request

[Ananth Chellappa]

Chet, Lawrence,
         Sincerely appreciate your time. Far as I understand, there is no
way to accomplish what I want - concisely : *get a true private mode* (no
logging to HISTFILE *OR* recall with history command after exiting
private-mode (toggle of history using set -/+ o) *without sacrificing
productivity*. That is, when you are *in private mode, you DO WANT recall
with !number and arrow keys. *Even this guy https://paulh.consulting/
thought it was easy before deciding it was worth $500 of his time to try
adding it :)

Naseeba's implementation gives me what I need. I'd like others to benefit
from it..

With current bash :

analog@DESKTOP-O264A5N ~ $ echo $HISTFILE
/home/analog/.bash_history
analog@DESKTOP-O264A5N ~ $ unset HISTFILE
analog@DESKTOP-O264A5N ~ $ echo a private command
a private command
analog@DESKTOP-O264A5N ~ $ echo an evil command
an evil command
analog@DESKTOP-O264A5N ~ $ h 10
 2143  echo $HISTFILE
 2144  set +o history
 2145  h 10
 2146  source /tmp/set_pm
 2147  search roberge
 2148  echo $HISTFILE
 2149  unset HISTFILE
 2150  echo a private command
 2151  echo an evil command
 2152  h 10
analog@DESKTOP-O264A5N ~ $ set HISTFILE=/home/analog/.bash_history
analog@DESKTOP-O264A5N ~ $ h 15
 2140  echo "set +o history" > /tmp/set_pm
 2141  . /tmp/set_pm
 2142  h 10
 2143  echo $HISTFILE
 2144  set +o history
 2145  h 10
 2146  source /tmp/set_pm
 2147  search roberge
 2148  echo $HISTFILE
 2149  unset HISTFILE
 2150  echo a private command   <---- Yikes, this was in private mode! I
shouldn't see this after "exiting"
 2151  echo an evil command     <---- private mode. LV suggested that using
HISTFILE unset/set would be be
 2152  h 10
 2153  set HISTFILE=/home/analog/.bash_history
 2154  h 15
