Add Separator Line Between Commands on Linux Terminal

If you are a person who often perform daily tasks via command line interface, you might have ever performed multiple commands at once (usually by adding "&&" between them). But, you might be confused when analyzing the output of every command and when the command is finished. So today, I'd like to show you how to add a handy separator line between commands on Linux Terminal.

As you can see the picture above, at the end of every command there will be a separator line followed by the time completion of related command. Are you interested in it? OK! Please open your text editor and paste the following code:

• # Fill with minuses
• # (this is recalculated every time the prompt is shown in function prompt_command):
• fill="--- "
• 
  
• reset_style='\[\033[00m\]'
• status_style=$reset_style'\[\033[0;90m\]' # gray color; use 0;37m for lighter color
• prompt_style=$reset_style
• command_style=$reset_style'\[\033[1;29m\]' # bold black
• # Prompt variable:
• 
  
• PS1="$status_style"'$fill \t\n'"$prompt_style"'${debian_chroot:+($debian_chroot)}\u@\h:\w\$'"$command_style "
• 
  
• # Reset color for command output
• # (this one is invoked every time before a command is executed):
• trap 'echo -ne "\e[0m"' DEBUG
• 
  
• 
  
• function prompt_command {
• 
  
• # create a $fill of all screen width minus the time string and a space:
• let fillsize=${COLUMNS}-9
• fill=""
• while [ "$fillsize" -gt "0" ]
• do
• fill="-${fill}" # fill with underscores to work on
• let fillsize=${fillsize}-1
• done
• 
  
• # If this is an xterm set the title to user@host:dir
• case "$TERM" in
• xterm*|rxvt*)
• bname=`basename "${PWD/$HOME/~}"`
• echo -ne "\033]0;${bname}: ${USER}@${HOSTNAME}: ${PWD/$HOME/~}\007"
• ;;
• *)
• ;;
• esac
• 
  
• }
• PROMPT_COMMAND=prompt_command

Save the above code as ".bash_ps1" (don't forget the dot character) and place it in your Home folder.
Lazy copying the code? Download the ".bash_ps1" file here.

Now, edit your ".bashrc" file which is located in your Home folder and append the below code:

• if [ -f "$HOME/.bash_ps1" ]; then
• . "$HOME/.bash_ps1"
• fi

Save the change and run the following command to "apply" your work:

• source ~/.bashrc
