What Others Think

This doesn't work with dash or ksh88 and the 500, while probably large enough is arbitrary. CL () { local WORDS padwidth extra pad WORDS="$*" padwidth="$(($(tput cols)-${#WORDS}-2))" # if padwidth is odd, in which case we need an extra char somewhere if [ $((padwidth%2)) -eq 1 ]; then extra='=' else extra='' fi padwidth=$((padwidth/2)) pad='=' while [ $((padwidth=padwidth-1)) -ne 0 ]; do pad="${pad}="; done printf "%s%s %s %s\n" $pad "$extra" "$WORDS" $pad }
