Preserve Bash History in Multiple Terminal Windows on Linux



Bash history is a powerful tool that can help you keep track of all the commands you've executed in your terminal. It can be especially useful when you're working with multiple terminal windows, as it allows you to easily switch between them and pick up where you left off. In this article, we'll show you how to preserve bash history in multiple terminal windows on Linux, and explain why it's so important.

Why Preserve Bash History?

Preserving bash history is important because it allows users to easily recall commands they have previously executed in the terminal. This can save time and effort by avoiding the need to re-enter the same commands over and over again.

Additionally, preserving bash history can help users troubleshoot any issues they may be having with their system or software. By reviewing the commands that have been executed, users can identify any mistakes or errors that may have occurred.

Furthermore, preserving bash history can serve as a reference for future use. By having a record of the commands executed, users can refer back to them in case they need to replicate a previous action or troubleshoot a similar problem.

Another benefit of preserving bash history is that it allows users to pick up where they left off. If they have closed the terminal or their system crashed, the history can act as a memory aid, making it easier to continue with the work they were doing previously.

Overall, preserving bash history is a useful tool that can improve the efficiency and productivity of users working in the terminal.

Why Preserve Bash History in Multiple Terminal Windows?

Preserving bash history in multiple terminal windows is important for several reasons.

Firstly, it can help you avoid repeating the same commands over and over again. If you're working on a project that requires you to run the same set of commands every time you open a new terminal window, you'll be able to simply recall them from your bash history, saving time and effort.

Secondly, it can help you troubleshoot any issues you're having. If you're running into a problem and you're not sure what commands you've executed, you can refer to your bash history to see what you've done. This can save you a lot of time and frustration when trying to solve a problem.

Additionally, preserving bash history in multiple terminal windows allows you to easily switch between them and pick up where you left off. This is especially useful when working on multiple projects or tasks simultaneously.

Lastly, preserving bash history in multiple terminal windows can also serve as a backup in case your terminal crashes or you accidentally close it. This way you can always have a record of the commands you've executed, which can be useful in case you need to refer back to them in the future.

How to Preserve Bash History in Multiple Terminal Windows

Preserving bash history in multiple terminal windows is actually quite simple. The first step is to ensure that your .bashrc file is configured to save your bash history. This file is located in your home directory, and it contains all the settings for your bash shell. To check that your .bashrc file is configured to save your bash history, open it in a text editor and look for the following line −

HISTSIZE=1000

This line tells bash to save the last 1000 commands you've executed. If you want to change the number of commands that are saved, simply edit this line and change the value to whatever you prefer.

Once you've confirmed that your .bashrc file is configured to save your bash history, you'll need to make sure that your terminal windows are configured to use the same .bashrc file. To do this, simply open the terminal window that you want to configure and type the following command −

source ~/.bashrc

This command tells the terminal to use the .bashrc file in your home directory, so all of your terminal windows will be using the same settings.

Conclusion

Preserving bash history in multiple terminal windows is a great way to save time and make your work more efficient. By following the steps outlined in this article, you'll be able to easily recall commands from your bash history, troubleshoot issues, and make sure that all of your terminal windows are using the same settings. With these tips, you'll be able to take control of your bash history and make your work more productive.
