Re: RH9 breaks bash ?



In regard to: RH9 breaks bash ?, Perry Hutchison said (at 11:50am on Dec...:

It's probably the echo, not the other stuff.  When I run your commands on
a Solaris box, with bash 2.05b, and do

	echo "${MY_TITLES}\c"

I get the backslashed output.  If I instead run

	builtin echo -e "${MY_TITLES}\c"

I get your expected result.

Well, changing your personal .bashrc seems like a more viable approach
than trying to change the system shell.  Why not detect what platform
and version of bash you have, and then customize how bash acts and
what options you give it based on what you've detected?

Look at $BASH_VERSION, $HOSTTYPE, $OSTYPE, and other variables that bash
sets for you, and customize your .bashrc based on those.
