When I try to print out some colored text using ANSI escape sequences via the built-in
echo command, it seems that the
e escape sequence in the string I provide is interpreted literally instead of as the "escape" it's supposed to represent. This only happens in Snow Leopard -- the examples below work as intended in Leopard.
echo does support the
-e switch since it correctly interprets
~ $ ~ $ echo " " ~ $ echo -e " " ~ $
But when I try to use
e, I get this:
~ $ echo -e "e[34mCOLORS" e[34mCOLORS ~ $
Like I said, in Leopard, the above would give me the string "COLORS" in color.
Does anyone know of a reason why this might be an intended change? How about a workaround for printing ANSI escape sequences from Bash scripts on Snow Leopard?
The Bash shell version on my Leopard machine is
3.2.48(1)-release on my Snow Leopard machine.
