When pressing Ctrl+Alt+T to open the terminal I get a blank screen with a simplistic input prompt.



Is it possible (by modifying ~/.bashrc perhaps) to display the current calendar with today highlighted and the current time?



If the time can be displayed in large numbers (using figlet?) that would be a bonus.

          Improved Version



          You can see the improved version here: https://askubuntu.com/a/1020693/307523



          It looks like this:



          Terminal Splash Screen




          Original Version





          You can print an introduction banner when the terminal is opened using the ~/.bashrc script. If you have figlet (sudo apt install figlet) you can take advantage of large letters to display the time:



          now



          In the first instance figlet is used to display the time and in the second a regular font is used.



          Additional screen examples using toilet



          now 3



          This screen uses fonts from the toilet package. The last example uses future font and is used in the code below. Additionally, the calendar is set to cyan color in the code below.



          The toilet package allows additional font types and formatting styles over the figlet package which it is forked from. To install the package use sudo apt install toilet after installing figlet as described above.



          The code



          Here is the code you need to make it all work. It's recommended to place this script in your /home/user/bin directory as it is automatically added to your path. This script is named now but you can use any unique name you like.



          #!/bin/bash

          # NAME: now
          # PATH: $HOME/bin
          # DESC: Display current calendar and time
          # CALL: Called from terminal or ~/.bashrc
          # DATE: Apr 6, 2017. Modified: Apr 10, 2017.

          # NOTE: To display all available toilet fonts use this one-liner:
          # for i in $TOILET_FONT_PATH:=/usr/share/figlet/*.t,flf; do j=$i##*/; toilet -d "$i%/*" -f "$j" "$j%.*"; done

          # calendar current month with today higlighted.
          # colors 00=bright white, 31=red, 32=green, 33=yellow, 34=blue, 35=purple,
          # 36=cyan, 37=white
          printf "33[36m" # color 36=cyan
          echo ""; cal;
          printf "33[00m" # color bright white (default)
          echo ""

          tput sc # Save cursor position.
          # Move up 9 lines
          while [ $((++i)) -lt 10 ]; do tput cuu1; done
          tput cuf 25 # Move 25 columns right

          # Do we have the toilet package?
          if hash toilet 2>/dev/null; then
          echo " "$(date +"%I:%M %P")" " |
          toilet -f future --filter border > /tmp/terminal
          # Do we have the figlet package?
          elif hash figlet 2>/dev/null; then
          echo $(date +"%I:%M %P") | figlet > /tmp/terminal
          # else use standard font
          else
          echo $(date +"%I:%M %P") > /tmp/terminal
          fi

          while IFS= read -r Time; do
          printf "33[01;32m" # color green
          printf "$Time"
          tput cud1 # Up one line
          tput cuf 25 # Move 25 columns right
          done < /tmp/terminal

          tput rc # Restore saved cursor position.

          exit 0


          Mark script as executable



          Copy this code into your editor and save it to the file now. Next mark it as executable using:



          sudo chmod +x now


          Add script to ~./bashrc



          Once this is completed you can type now in the terminal and you will see the calendar and time. To wrap it all up and have it automatically displayed each time you open the terminal:



          • Edit the file ~/.bashrc

          • Go to the end and insert a new line containing now

          • Save the file

          Now when opening the terminal you will be greeted with the current day highlighted on current month's calendar followed by the current time.



          Dissecting the code



          Here we'll briefly look at how the code works without discussing every line.




          figlet and toilet packages



          The script first checks if toilet is installed with the hash command. If so that is used to display time. If not figlet is used if installed. If neither are installed a regular font is used.



          In the code above a comment can be copied to your command line and executed to show available figlet and toilet fonts on your terminal:



          for i in $TOILET_FONT_PATH:=/usr/share/figlet/*.t,flf; do j=$i##*/; toilet -d "$i%/*" -f "$j" "$j%.*"; done


          To change the font used for time display search the code for this line:



          toilet -f future --filter border > /tmp/terminal


          and change the font name future to the font name you choose. Keep in mind some fonts are too large to fit on the display.



          Selecting colors



          Set the color you want for the calendar and the time separately. In the above code, notice the command:



          printf "33[36m" # color 36=cyan


          Change the last two digits to the color code you want to use. From tinkering with the code I found these values:




          00=bright white, 31=red, 32=green, 33=yellow, 34=blue, 35=purple, 36=cyan, 37=white




          If you find additional color codes please post a comment below or update this answer.

          If you just want a simple time and date you can add these to the end of your .bashrc:



          echo -e "Welcome to [$(hostname)] You are logged in as user [$USER]"
          echo -e "Local time: [$(date)]"


          which will display the following when you login:



          Welcome to [deathstar] You are logged in as user [skywalker]
          [Local time]: Sun Apr 9 10:18:11 CDT 2017.


          I have a python script I wrote that will add local weather and your WAN and LAN IPs to your .bashrc file as well. Set a cronjob to update the weather. It comes with a sample .bashrc also



          It will display:



          Welcome to [deathstar] You are logged in as user [skywalker]
          [Local time]: Sun Apr 9 10:18:11 CDT 2017.
          [Local weather]: 68.68 F with few clouds
          [Your public IP is]: 1.2.3.4 [Local IP]: 192.168.2.6


          If you want to take it a step further you can add extra colors and formatting to make your values match your profile

            Terminal Splash Screen




            Original Version





            You can print an introduction banner when the terminal is opened using the ~/.bashrc script. If you have figlet (sudo apt install figlet) you can take advantage of large letters to display the time:



            now



            In the first instance figlet is used to display the time and in the second a regular font is used.



            Additional screen examples using toilet



            now 3



            This screen uses fonts from the toilet package. The last example uses future font and is used in the code below. Additionally, the calendar is set to cyan color in the code below.



            The toilet package allows additional font types and formatting styles over the figlet package which it is forked from. To install the package use sudo apt install toilet after installing figlet as described above.



            The code



            Here is the code you need to make it all work. It's recommended to place this script in your /home/user/bin directory as it is automatically added to your path. This script is named now but you can use any unique name you like.



            #!/bin/bash

            # NAME: now
            # PATH: $HOME/bin
            # DESC: Display current calendar and time
            # CALL: Called from terminal or ~/.bashrc
            # DATE: Apr 6, 2017. Modified: Apr 10, 2017.

            # NOTE: To display all available toilet fonts use this one-liner:
            # for i in $TOILET_FONT_PATH:=/usr/share/figlet/*.t,flf; do j=$i##*/; toilet -d "$i%/*" -f "$j" "$j%.*"; done

            # calendar current month with today higlighted.
            # colors 00=bright white, 31=red, 32=green, 33=yellow, 34=blue, 35=purple,
            # 36=cyan, 37=white
            printf "33[36m" # color 36=cyan
            echo ""; cal;
            printf "33[00m" # color bright white (default)
            echo ""

            tput sc # Save cursor position.
            # Move up 9 lines
            while [ $((++i)) -lt 10 ]; do tput cuu1; done
            tput cuf 25 # Move 25 columns right

            # Do we have the toilet package?
            if hash toilet 2>/dev/null; then
            echo " "$(date +"%I:%M %P")" " |
            toilet -f future --filter border > /tmp/terminal
            # Do we have the figlet package?
            elif hash figlet 2>/dev/null; then
            echo $(date +"%I:%M %P") | figlet > /tmp/terminal
            # else use standard font
            else
            echo $(date +"%I:%M %P") > /tmp/terminal
            fi

            while IFS= read -r Time; do
            printf "33[01;32m" # color green
            printf "$Time"
            tput cud1 # Up one line
            tput cuf 25 # Move 25 columns right
            done < /tmp/terminal

            tput rc # Restore saved cursor position.

            exit 0


            Mark script as executable



            Copy this code into your editor and save it to the file now. Next mark it as executable using:



            sudo chmod +x now


            Add script to ~./bashrc



            Once this is completed you can type now in the terminal and you will see the calendar and time. To wrap it all up and have it automatically displayed each time you open the terminal:



            • Edit the file ~/.bashrc

            • Go to the end and insert a new line containing now

            • Save the file

            Now when opening the terminal you will be greeted with the current day highlighted on current month's calendar followed by the current time.



            Dissecting the code



            Here we'll briefly look at how the code works without discussing every line.




            figlet and toilet packages



            The script first checks if toilet is installed with the hash command. If so that is used to display time. If not figlet is used if installed. If neither are installed a regular font is used.



            In the code above a comment can be copied to your command line and executed to show available figlet and toilet fonts on your terminal:



            for i in $TOILET_FONT_PATH:=/usr/share/figlet/*.t,flf; do j=$i##*/; toilet -d "$i%/*" -f "$j" "$j%.*"; done


            To change the font used for time display search the code for this line:



            toilet -f future --filter border > /tmp/terminal


            and change the font name future to the font name you choose. Keep in mind some fonts are too large to fit on the display.



            Selecting colors



            Set the color you want for the calendar and the time separately. In the above code, notice the command:



            printf "33[36m" # color 36=cyan


            Change the last two digits to the color code you want to use. From tinkering with the code I found these values:




            00=bright white, 31=red, 32=green, 33=yellow, 34=blue, 35=purple, 36=cyan, 37=white




            If you find additional color codes please post a comment below or update this answer.

            • The bashrc shouldn't produce any output (though I can't remember the reason why). So instead of just now, it may be better to put this line in it: PROMPT_COMMAND='[[ $now_already_run != yes ]] && now_already_run=yes && now'

            @wjandrea The closest I could find is this: stackoverflow.com/questions/12440287/… however it has a different solution. Let's leave our comments here until someone reports a problem that can be reproduced and then fix it?

            There's certainly a niche case where running a command with bash -ic <command> produces unexpected output, but I can't think of a situation where that would be a problem.

            Colors are ANSI escape sequences. More info and a list here: misc.flogisoft.com/bash/tip_colors_and_formatting

            If you just want a simple time and date you can add these to the end of your .bashrc:



            echo -e "Welcome to [$(hostname)] You are logged in as user [$USER]"
            echo -e "Local time: [$(date)]"


            which will display the following when you login:



            Welcome to [deathstar] You are logged in as user [skywalker]
            [Local time]: Sun Apr 9 10:18:11 CDT 2017.


            I have a python script I wrote that will add local weather and your WAN and LAN IPs to your .bashrc file as well. Set a cronjob to update the weather. It comes with a sample .bashrc also



            It will display:



            Welcome to [deathstar] You are logged in as user [skywalker]
            [Local time]: Sun Apr 9 10:18:11 CDT 2017.
            [Local weather]: 68.68 F with few clouds
            [Your public IP is]: 1.2.3.4 [Local IP]: 192.168.2.6


            If you want to take it a step further you can add extra colors and formatting to make your values match your profile
