Bash prompt display HH:MM:SS

  • 772

I learned from the question date - HH:MM:SS (with AM/PM) 12 Hour Timestamp for Bash Prompt - Unix & Linux Stack Exchange and fine-tune my prompt as:

export PS1='\D{%r}:\[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]:\n$ '
08:52:31 PM:me@host:~:
$

The time format is not very comfortable, the result I desire is 

   08:52PM me@host~:

How could I get such a HH:MM(AM/PM) format\

The final result

export  PS1='\D{%I:%M%p %d/%m %A}:\[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]:\n$ '

$ ls '$tty'

ps1

    The supported formats are those documented in man date. So instead of

       %r     locale's 12-hour clock time (e.g., 11:11:04 PM)

    you can use

       %I     hour (01..12)
   %M     minute (00..59)
   %p     locale's equivalent of either AM or PM; blank if not known

    So change \D{%r} to \D{%I:%M%p}

  2. Use \@ (the current time in 12-hour am/pm format) instead of \D{%r}, that produces times in HH:MM (AM|PM) format.
