1、创建item主题

2、创建shell脚本

vim ~/.oh-my-zsh/custom/iTrem2-ssh.zsh

3、将以下内容写入脚本(iTrem2-ssh.zsh)中

# tabc <profile name> do the profile change
function tabc() {
  NAME=$1; if [ -z "$NAME" ]; then NAME="Default"; fi 
  # if you have trouble with this, change
  # "Default" to the name of your default theme
  echo -e "\033]50;SetProfile=$NAME\a"
}

# reset the terminal profile to Default  when exit from the ssh session
function tab-reset() {
    NAME="Default"
    echo -e "\033]50;SetProfile=$NAME\a"
}

# selecting different terminal profile according to ssh'ing host
# tabc <profile name> do the profile change
#   1. Production profile to production server (ssh eranga@production_box) 
#   2. Staging profile to staging server(ssh eranga@staging_box) 
#   3. Other profile to any other server(test server, amazon box etc)
function colorssh() {
    if [[ -n "$ITERM_SESSION_ID" ]]; then
        trap "tab-reset" INT EXIT
        if [[ "$*" =~ "dev*" ]]; then
            tabc dev
        elif [[ "$*" =~ "test*" ]]; then
            tabc test 
        elif [[ "$*" =~ "online*" ]]; then
            tabc online 
        else
            tabc Default
        fi
    fi
    ssh $*
}
compdef _ssh tabc=ssh

# creates an alias to ssh
# when execute ssh from the terminal it calls to colorssh function
alias ssh="colorssh"

4、修改ssh config 中的连接名称(名称中有关键词即可)
例1：ssh ***-online

例2：ssh test

vim ~/.bash_profile
# 在最底下填上这个
echo -e "\033]50;SetProfile=Default\a"
