roylez 写了：动态screen title，需要与screen配合。

代码： 全选

#screen integration to set caption bar dynamically
function title {
if [[ $TERM == "screen" || $TERM == "screen.linux" ]]; then
    # Use these two for GNU Screen:
    print -nR $'\033k'$1$'\033'\\\

    print -nR $'\033]0;'$2$'\a'
elif [[ $TERM == "xterm" || $TERM == "urxvt" ]]; then
    # Use this one instead for XTerms:
    print -nR $'\033]0;'$*$'\a'
    #trap 'echo -ne "\e]0;$USER@$HOSTNAME: $BASH_COMMAND\007"' DEBUG
fi
}

#set screen title if not connected remotely
function precmd {
    title "`print -Pn "%~" | sed "s:\([~/][^/]*\)/.*/:\1...:"`" "$TERM $PWD"
    echo -ne '\033[?17;0;127c'
}

function preexec {
    emulate -L zsh
    local -a cmd; cmd=(${(z)1})
    if [[ $cmd[1]:t == "ssh" ]]; then
        title "@"$cmd[2] "$TERM $cmd"
    elif [[ $cmd[1]:t == "sudo" ]]; then
        title "#"$cmd[2]:t "$TERM $cmd[3,-1]"
    elif [[ $cmd[1]:t == "for" ]]; then
        title "()"$cmd[7] "$TERM $cmd"
    elif [[ $cmd[1]:t == "svn" ]]; then
        title "$cmd[1,2]" "$TERM $cmd"
    else
        title $cmd[1]:t "$TERM $cmd[2,-1]"
    fi 
}

截个图瞅瞅效果
screen这种东东我一般不用
容易晕脑
我还有更好的办法 赶明个儿发个贴介绍下我的秘密武器
