1、安装brew（找了很多🔗，就这个博主的好用）

Mac如何安装brew？_行走的码农00的博客-CSDN博客_mac brew

2、安装lrzsz

brew install lrzsz  

检查是否安装成功

brew list

定位lrzsz的安装目录

brew list lrzsz

执行结果如下：

 3、配置rz sz 进行上传下载

进入lrzsz的安装目录bin下

cd /opt/homebrew/bin

创建两个文件：

$FILE 后面的配置路径为：lrzsz的安装目录bin

sudo vim iterm2-recv-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 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"
    /opt/homebrew/bin/rz -E -e -b
    sleep 1
    echo
    echo
    echo \# Sent \-\> $FILE
fi

sudo vim 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)&\"\")"`

    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)&\"\")"`

if [[ $FILE = "" ]]; then
    echo Cancelled.
    # Send ZModem cancel
    echo -e \\x18\\x18\\x18\\x18\\x18
    sleep 1
    echo
    echo \# Cancelled transfer
else
    /opt/homebrew/bin/sz "$FILE" -e -b
    sleep 1
    echo
    echo \# Received $FILE
fi

给予权限：

chmod -R 777 iterm2-recv-zmodem.shchmod -R 777 iterm2-send-zmodem.sh

4、iTerm2 配置添加rz sz 功能

点击 iTerm2 的设置界面 Perference-> Profiles -> Default -> Advanced -> Triggers 的 Edit 按钮

 配置内容如下：

第一行：

rz waiting to receive.\*\*B0100

Run Silent Coprocess

/opt/homebrew/bin/iterm2-send-zmodem.sh

第二行：

\*\*B00000000000000

Run Silent Coprocess

/opt/homebrew/bin/iterm2-recv-zmodem.sh

Instant 打钩的话，不需要重启item

 然后就可以使用rz、rz命令啦~
