What eventually worked very well for me, after reading all your posts,
was to use "echo -e" to set the color variables, then I don't need any
special treatment after that in sed.
eg
export COLOR_WARN=`echo -e '\e[33;40m'`
then I can just do
echo "This is a [WARNING] message " | sed -e
's/.*[WARNING].*/'${COLOR_WARN}'&'${COLOR_RESET}'/g;'
Thanks for all your help. The only real problem I'm having at this
point is matching square brackets. Since square brackets need to be
escaped even when maching a set of characters, I don't know how to tell
it to match an open square bracket then characters in a set, then a
close square bracket.
This is what I mean: Lets say I want to match [ followed by lower case
letters or a period, followed by ].
MATCH: [net.thekramers.foo]
NOT A MATCH: net.thekramers.foo
NOT A MATCH: [net.thekramers.Foo!]
