I also see why there is a difference between PS1 and echo colors.. so I was wrong about my first post since you weren’t using colors for your PS1

At least I hope that it did :D

But like I said the your color codes worked fine up to a point. But some times my terminal wouldn’t be able to run ctrl+u to clear the current line it would stop at a random char on the line.

But this problem might have been since I wasn’t using echo -e “” I was using “\e”

I wonder what the reasoning for this is?Maybe it is only required on PS1′s?

First thank you for your insights and feedback.

What problems were you having and how is it these color codes fixed it ?

I use the codes primarily to set the color via echo
(ie echo -e ${GREEN}green )

When I changed the syntax as you suggested I get “\[\]” printed in the echo command
(echo -e ${GREEN}green ).

My syntax seems to “works for me” when I use it to set PS1 for example PS1=”${GREEN}/w”

There is a slight error with regards to your colors. (I have been using them for a while and never noticed till yesterday when my shell started to act up).

BLUE=’\e[0;34m’
RED=’\e[0;31m’
GREEN=’\e[0;32m’

Should be.
BLUE=’\[\e[0;34m\]’
RED=’\[\e[0;31m\]’
GREEN=’\[\e[0;32m\]’

Notice the first \[ and the last \]

Or maybe this is for a pure bash shell.

I am sure you know this, but for the benefit of others following this conversation, you can not use selinux at the same time as apparmor (they are mutually exclusive).

There is a benefit of rbash but please keep in mind as I *tried* to point out and jdong made perfectly clear (to me at least), it is not *too* difficult to break out of rbash.

apparmor and selinux will both be configured somewhat different, but both are more secure then rbash.

If you are already using apparmor and/or selinux, rbash does not, IMO, add much.
