前言

闲来无事配置下Iterm2让其支持 rzsz 命令，但是没想到小小的一个配置还出了问题。。。

安装

我们先按照网上的教程走一遍

安装 lrzsz

brew install lrzsz

配置 iterm2

脚本

拉取 github.com/laggardkern… 两个 sh 文件，拷贝到 /usr/local/bin 文件夹中。

如果没有上述的两个文件，复制如下

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-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

一定要赋予执行权限：

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

配置

打开 iterm2，打开需要配置的 Profile 点击 Session->Edit Session-> Advanced 的 tab 页 -> Triggers - Edit，添加两条规则：

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

Regular expression: \*\*B00000000000000
Action: Run Silent Coprocess
Parameters: /usr/local/bin/iterm2-recv-zmodem.sh

配置完毕，看似很完美然后运行,然后。。。。

异常

难受了，头疼了，所幸iterm2还把异常给你看

这时候点击 view Errors能看到如下异常 /usr/local/bin/iterm2-send-zmodem.sh: line 18: /usr/local/bin/sz: No such file or directory 原来是找不到 之前安装的sz、rz,这时候只需要修改上述脚本的rz、sz路径即可

找brew安装地址

brew list lrzsz

修改上述两个脚本如下

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"
	/opt/homebrew/Cellar/lrzsz/0.12.20_1/bin/rz -E -e -b --bufsize 4096
	sleep 1
	echo
	echo
	echo \# Sent \-\> $FILE
fi

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 [[ $FILE = "" ]]; then
	echo Cancelled.
	# Send ZModem cancel
	echo -e \\x18\\x18\\x18\\x18\\x18
	sleep 1
	echo
	echo \# Cancelled transfer
else
	/opt/homebrew/Cellar/lrzsz/0.12.20_1/bin/sz "$FILE" --escape --binary --bufsize 4096
	sleep 1
	echo
	echo \# Received $FILE
fi

完美解决
