By default, the history<\/code> command in Bash shows a list of recently executed commands with their respective line numbers. However, it does not display the date and time when each command was executed. (www.utahcnacenters.com<\/a>) To show the date and time for each command in the Bash history, you can set the HISTTIMEFORMAT<\/code> environment variable.<\/p>\n

Here’s how to do it:<\/p>\n

    \n
  1. Open your Bash configuration file (~\/.bashrc<\/code> or ~\/.bash_profile<\/code>).<\/li>\n
  2. Add the following line to the file:<\/li>\n<\/ol>\n
    \n
    <\/div>\n
    export HISTTIMEFORMAT=\"%F %T \"<\/span>
    \n<\/code><\/div>\n<\/div>\n

    This sets the HISTTIMEFORMAT<\/code> environment variable to a string that specifies the date and time format. The format string %F %T<\/code> represents the date and time in the format YYYY-MM-DD HH:MM:SS<\/code>.<\/p>\n

      \n
    1. Save the file and close it.<\/li>\n
    2. Reload the Bash configuration by running the following command:<\/li>\n<\/ol>\n
      \n
      <\/div>\n
      source<\/span> ~\/.bashrc
      \n<\/code><\/div>\n<\/div>\n

      Now, when you run the history<\/code> command, it will display the date and time for each command in the Bash history, as shown below:<\/p>\n

      \n
      <\/div>\n
      1 2022-02-15 14:07:21 ls<\/span>
      \n 2 2022-02-15 14:07:25 cd<\/span> ..
      \n 3 2022-02-15 14:07:29 ls<\/span>
      \n 4 2022-02-15 14:07:34 history<\/span>
      \n<\/code><\/div>\n<\/div>\n

      This can be helpful in identifying when a particular command was executed and for troubleshooting purposes.<\/p>\n","protected":false},"excerpt":{"rendered":"
