Bash History Display Date And Time For Each Command

To display the date and time for each command in the Bash history, you can use the HISTTIMEFORMAT environment variable.

The HISTTIMEFORMAT environment variable allows you to specify a format for the date and time that is displayed with each command in the Bash history.

To display the date and time for each command in the Bash history, you can set the HISTTIMEFORMAT environment variable to a format that includes the date and time.

For example, to display the date and time in the format "%F %T" (YYYY-MM-DD HH:MM:SS), you can use the following command:

# Set the HISTTIMEFORMAT environment variable
export HISTTIMEFORMAT="%F %T "

This will cause the date and time to be displayed with each command in the Bash history.

To display the Bash history with the date and time, you can use the history command. For example:

# Display the Bash history with the date and time
history

This will output the Bash history with the date and time displayed for each command, such as:

1  2021-12-10 12:34:56 ls
    2  2021-12-10 12:35:01 pwd
    3  2021-12-10 12:35:03 cat file.txt

Overall, the HISTTIMEFORMAT environment variable is a useful tool for displaying the date and time for each command in the Bash history. It allows you to customize the format of the date and time and easily view the history of commands executed in Bash.
