“In this tutorial, we studied ways to preserve Bash history in multiple terminal windows on Linux .

In the beginning, we discussed the history feature of the Bash shell and its default behavior. Next, we discussed the approach and solutions to our problem statement. Finally, we also offered a way to create a separate history file for each session.”

Access the .bashrc configuration file

1

sudo nano ~/.bashrc

Then inside that file we add:

1
2
3

HISTCONTROL=ignoredups:erasedups
shopt -s histappend
PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND$'n'}history -a; history -c; history -r"

We save the file and then we restart the system or do source ~/.bashrc to load configurations.
