笔者一直使用iTerm2作为日常工作的终端工具，用起来非常不错。突然到了某个的今天，想把一些脚本文件上传到服务器上的时候，自然而然的就想到了lrzsz。于是就登录到服务器上，然后输入rz命令，duang～duang～duang，iTerm2不但没有弹出文件选择窗口，还卡住了！

赶紧求助万能的谷歌，还好在Github上找到了一个解决方法，特此记录在案！

1️⃣ 安装lrzsz

在mac中先安装lrzsz：

brew install lrzsz

2️⃣ 创建rzsz脚本

在mac的/usr/local/bin/目录下，分别创建iterm2-send-zmodem.sh 和iterm2-recv-zmodem.sh两个脚本文件，并设置权限为777。

然后两个文件的内容分别如下：

iterm2-recv-zmodem.sh

#!/bin/bash

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 [[ $FILE = "" ]]; then
	echo Cancelled.
	# Send ZModem cancel
	echo -e \\x18\\x18\\x18\\x18\\x18
	sleep 1
	echo
	echo \# Cancelled transfer
else
	cd "$FILE"
	/usr/local/bin/rz -E -e -b --bufsize 4096
	sleep 1
	echo
	echo
	echo \# Sent \-\> $FILE
fi

iterm2-recv-zmodem.sh

#!/bin/bash

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)&\"\")"`
else
	FILE=`osascript -e 'tell application "iTerm2" to activate' -e 'tell application "iTerm2" 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)&\"\")"`
fi
if [[ $FILE = "" ]]; then
	echo Cancelled.
	# Send ZModem cancel
	echo -e \\x18\\x18\\x18\\x18\\x18
	sleep 1
	echo
	echo \# Cancelled transfer
else
	/usr/local/bin/sz "$FILE" --escape --binary --bufsize 4096
	sleep 1
	echo
	echo \# Received $FILE
fi

3️⃣ 设置iTerm2

打开Settings->Profiles->Advanced，点击Edit。

在弹出框中新增两条Trigger。

Trigger填写的的内容分别如下：

第1个

• Regular expression: rz waiting to receive.**B0100
• Action: Run Silent Coprocess
• Parameters: /usr/local/bin/iterm2-send-zmodem.sh
• Instant: selected

第2个

• Regular expression: **B0100000023be50
• Action: Run Silent Coprocess
• Parameters: /usr/local/bin/iterm2-recv-zmodem.sh
• Instant: selected

最后，再次在iTerm2中输入rz命令，就能正常弹出文件选择框了。
