    # Command Prompt
    ############################################################################

    ##### Prompt escapes
    # Bash allows these prompt strings to be customized by inserting a
    # number of backslash-escaped special characters that are
    # decoded as follows:
    #  \a         an ASCII bell character (07)
    #  \d         the date in "Weekday Month Date" format (e.g., "Tue May 26")
    #  \D{format} the format is passed to strftime(3) and the result
    #             is inserted into the prompt string an empty format
    #             results in a locale-specific time representation.
    #             The braces are required
    #  \e         an ASCII escape character (033)
    #  \h         the hostname up to the first `.'
    #  \H         the hostname
    #  \j         the number of jobs currently managed by the shell
    #  \l         the basename of the shell's terminal device name
    #  \n         newline
    #  \r         carriage return
    #  \s         the name of the shell, the basename of $0 (the portion following
    #             the final slash)
    #  \t         the current time in 24-hour HH:MM:SS format
    #  \T         the current time in 12-hour HH:MM:SS format
    #  \@         the current time in 12-hour am/pm format
    #  \A         the current time in 24-hour HH:MM format
    #  \u         the username of the current user
    #  \v         the version of bash (e.g., 2.00)
    #  \V         the release of bash, version + patch level (e.g., 2.00.0)
    #  \w         the current working directory, with $HOME abbreviated with a tilde
    #  \W         the basename of the current working directory, with $HOME
    #             abbreviated with a tilde
    #  \!         the history number of this command
    #  \#         the command number of this command
    #  \$         if the effective UID is 0, a #, otherwise a $
    #  \nnn       the character corresponding to the octal number nnn
    #  \\         a backslash
    #  \[         begin a sequence of non-printing characters, which could be used
    #             to embed a terminal control sequence into the prompt
    #  \]         end a sequence of non-printing characters
    #
    #  The command number and the history number are usually different:
    #  the history number of a command is its position in the history
    #  list, which may include commands restored from the history file
    #  (see HISTORY below), while the command number is the position in
    #  the sequence of commands executed during the current shell session.
    #  After the string is decoded, it is expanded via parameter
    #  expansion, command substitution, arithmetic expansion, and quote
    #  removal, subject to the value of the promptvars shell option (see
    #  the description of the shopt command under SHELL BUILTIN COMMANDS
    #  below).

    # Multi lines prompt. If you’re the type who wants to pack your prompt full of information, then here’s the one for you. This one is a multi-line prompt containing date/time, full path, user and host, active terminal, even file count and space usage
    # PS1="\n\[\033[35m\]\$(/bin/date)\n\[\033[32m\]\w\n\[\033[1;31m\]\u@\h: \[\033[1;34m\]\$(/usr/bin/tty | /bin/sed -e 's:/dev/::'): \[\033[1;36m\]\$(/bin/ls -1 | /usr/bin/wc -l | /bin/sed 's: ::g') files \[\033[1;33m\]\$(/bin/ls -lah | /bin/grep -m 1 total | /bin/sed 's/total //')b\[\033[0m\] -> \[\033[0m\]"
    # Color manage your prompt. There’s nothing particularly fancy about this prompt, other than the good use of color to separate the different pieces of information. As you can see, it provides time, username, hostname, and current directory. Fairly minimal but useful.
    PS1="\[\033[35m\]\t\[\033[m\]-\[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h: \[\033[33;1m\]\w\[\033[m\]\n> "
