bash - printf colours not working from .bash_logout -


i'm trying use this lovely script on logout ubuntu box i'm ssh'd into. if invoke manually, colours correct. however, whenever it's run .bash_logout, every line white , prefixed colour code:

\x1b[38;5;160;01m  .d8888b.  8888888888 8888888888      y88b   d88p  .d88888b.  888     888   \x1b[38;5;196;01m d88p  y88b 888        888              y88b d88p  d88p" "y88b 888     888   \x1b[38;5;202;01m  "y888b.   8888888    8888888            y888p    888     888 888     888   \x1b[38;5;208;01m     "y88b. 888        888                 888     888     888 888     888   \x1b[38;5;214;01m       "888 888        888                 888     888     888 888     888   \x1b[38;5;220;01m y88b  d88p 888        888                 888     y88b. .d88p y88b. .d88p   \x1b[38;5;226;01m  "y8888p"  8888888888 8888888888          888      "y88888p"   "y88888p"

term set xterm-256color in both vm , host (os x 10.11). tried using echo -e, did prepend colour string -e. adding contents of script directly .bash_logout works, though seems messy. thoughts?

in posix shell, cannot use \xxx escapes in printf command; can use octal notation. using . or source executes script current bash process instead of using posix shell. bash seeyou have worked well.

a posix-compliant version of script change first line to:

esc_seq="\033[38;5;"

of course, there no particular reason make code executed .bash_logout posix-compliant, since file specific bash.
