在macOS iterm2 上使用 zmodem (rz/sz)

1. 安装支持 rz 和 sz 命令的 lrzsz

brew install lrzsz

2. 在本地 /usr/local/bin/ 目录下分别创建 iterm2-send-zmodem.sh 和 iterm2-recv-zmodem.sh 两个脚本

iterm2-send-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

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

3. 设置两个脚本的可执行权限

chmod +x /usr/local/bin/iterm2-*

4.设置Iterm2的Tirgger特性，profiles->default->editProfiles->Advanced中的Tirgger
添加两条trigger，分别设置 Regular expression，Action，Parameters，Instant 如下：

Regular expression	Action	Parameters	Instant	Enabled
rz waiting to receive.\*\*B0100	Run Silent Coprocess	/usr/local/bin/iterm2-send-zmodem.sh	✔	✔
\*\*B00000000000000	Run Silent Coprocess	/usr/local/bin/iterm2-recv-zmodem.sh	✔	✔
