No, this doesn't solve the problem for all commands, e.g. with: sww () { svnwrapper diff "$@" | wdiff -n -w $'\033[30;41m' -x $'\033[0m' -y $'\033[30;42m' -z $'\033[0m' -d } where svnwrapper and wdiff are external command. -- Vincent Lefèvre - Web: 100% accessible validated (X)HTML - Blog: Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
