iTerm2配置rz/sz上传下载文件

一、iTerm2的Triggers功能

关于iTerm2的 Triggers 功能，官方的介绍是：

A trigger is an action that is performed when text matching some regular expression is received in a terminal session.

即：触发器是在终端会话中收到与某个正则表达式匹配的文本时执行的动作。

二、配置rs/zs

2.1、一键脚本

curl -sSLf https://git.io/bugwz-sh-iterm2-rzsz | sh

该脚本作用如下：

使用指令 brew install lrzsz 安装 lrzsz 软件；
下载 iterm2-send-zmodem.sh 和 iterm2-recv-zmodem.sh 到 /usr/local/bin/ 目录；
提示在 iTerm2 中进行后续的操作步骤；

2.2、单独操作步骤

安装lrzsz：

brew install lrzsz

在 /usr/local/bin 目录中新增iterm2-send-zmodem.sh 脚本（内容如下），并设置可执行权限：chmod +x iterm2-send-zmodem.sh

osascript -e 'tell application "iTerm2" to version' > /dev/null 2>&1 && NAME=iTerm2 || NAME=iTerm  
if [ "$NAME" = "iTerm" ]; then  
    FILE=$(osascript -e 'tell application "iTerm" to activate' -e 'tell application "iTerm" to set thefile to choose file with prompt "Choose a file to send"' -e "do shell script ( \"echo \"&(quoted form of POSIX path of thefile as Unicode text)&\"\" )")

    # Send ZModem cancel  
    echo \\x18\\x18\\x18\\x18\\x18  
    sleep 1  
    echo  
    echo \# Cancelled transfer  
else  
    /usr/local/bin/sz "$FILE" --escape --binary --bufsize 4096  
    sleep 1  
    echo  
    echo  
    echo "# Received $FILE"  
fi

在 /usr/local/bin 目录中新增iterm2-recv-zmodem.sh 脚本（内容如下），并设置可执行权限：chmod +x iterm2-recv-zmodem.sh

#!/bin/bash  
# shellcheck shell=dash

osascript -e 'tell application "iTerm2" to version' > /dev/null 2>&1 && NAME=iTerm2 || NAME=iTerm  
if [ "$NAME" = "iTerm" ]; then  
    FILE=$(osascript -e 'tell application "iTerm" to activate' -e 'tell application "iTerm" to set thefile to choose folder with prompt "Choose a folder to place received files in"' -e "do shell script (\"echo \"&(quoted form of POSIX path of thefile as Unicode text)&\"\")")  
else  
    FILE=$(osascript -e 'tell application "iTerm2" to activate' -e 'tell application "iTerm2" to set thefile to choose folder with prompt "Choose a folder to place received files in"' -e "do shell script (\"echo \"&(quoted form of POSIX path of thefile as Unicode text)&\"\")")  
fi  
  
if [ "$FILE" = "" ]; then  
    echo Cancelled.  
    # Send ZModem cancel  
    echo \\x18\\x18\\x18\\x18\\x18  
    sleep 1  
    echo  
    echo \# Cancelled transfer  
else  
    cd "$FILE" || exit  
    /usr/local/bin/rz --rename --escape --binary --bufsize 4096   
    sleep 1  
    echo  
    echo  
    echo "# Sent -> $FILE"  
fi

打开iTerm2软件，按照如下步骤配置 Triggers：
- 打开 Preferences...；
- 选择 Profiles 标签页，并在左侧选择对应的 Profile Name；
- 点击右侧的 Advanced 标签页；
- 点击 Triggers 栏目下的 Edit 按钮，新增触发器，具体配置如下所示；

Regular Expression	Action	Parameters	Instant
rz waiting to receive.\\B0100	Run Silent Coprocess…	/usr/local/bin/iterm2-send-zmodem.sh	checked
\\B00000000000000	Run Silent Coprocess…	/usr/local/bin/iterm2-recv-zmodem.sh	checked
