  1. What is Bash<\/strong>\n
      \n
    • Bash is a shell program that enables you to pass commands to the operating system (in this case Linux) and have them executed<\/li>\n<\/ul>\n<\/li>\n\n\n\n

    • How does one check the version of the Bash shell<\/strong><\/h4>\n
        \n
      • Checking the bash version helps Linux users in many cases, including troubleshooting and finding the currently available version in the system. If you are a regular bash user, it is good to check the bash version and keep it up to date as per the latest updates available. However, if you are a newbie in bash scripting, then you probably have never encountered a situation where you need to check the bash version.<\/span><\/li>\n\n\n\n
      • The Simple Approach\n
          \n
        • The following command is the easiest way to know the bash version:

          <\/p>bash\u00a0–version

          <\/p>\"checking-bash-version\"From the above result, you can see the current bash version of the system is 5.2.21(1).Built in $BASH_VERSION variable<\/li>\n\n\n\n

        • Another method to check the bash\u2019s version is to enter the content of the bash shell\u2019s variable as follows:

          <\/p>echo\u00a0$BASH_VERSION

          <\/p>\"echo-to-check-the-bash-version\"The Shell Script\n

            \n
          • It is also possible to check the bash version through a shell script. First, create a new shell script using the nano command, create a new bash file named check-bash-version.sh, and make it executable using the chmod command:nano\u00a0~\/check-bash-version.shchmod\u00a0+x check-bash-version.sh

            <\/p>Next, add the following lines to your script:

            <\/p>#!\/bin\/bash echo”Checking the bash version….”echo\u00a0“The Bash version is\u00a0$BASH_VERSION\u00a0!”

            <\/p>\"shell-scripting-to-check-the-bash-version\"Now, check the bash version by running the script as follows:.\/check-bash-version.sh

            <\/p>\"executing-the-shell-scripting\"Using the Shortcut KeyMeanwhile, you can use the shortcut key \u2018 Ctrl+X followed by \u2018Ctrl+V\u2019, and you may see the bash version on your screen as seen in the below image:\"key-board-shortcut-key\"From the Package Manager<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n\n\n\n

          • Through the package manager, you can simply run a single command to view the bash version.yum info\u00a0bash\u00a0(for\u00a0CentOS\/RHEL)pkg info\u00a0bash\u00a0(for\u00a0FreeBSD)apk info\u00a0bash\u00a0(for\u00a0Alpine Linux)apt info\u00a0bash\u00a0(for\u00a0Ubuntu)

            <\/p>\"apt-info-bash-scripting\"
