rz/sz 命令卡住的解决

通过 rz/sz 向服务器传输文件时，文件选择框没弹起，而是出现等待卡死的界面：

$rz -be

�z waiting to receive.**B0100000063f694

奇怪的是首次在本机 mac 上通过 iTerm2 使用时是成功的，过了几天才出现的该问题。

无奈查看解决方案，发现需要进行如下一系列操作。

安装 lrzsz

首先需要在本机安装 rz/sz 命令。

$brew installlrzsz

检查安装：

$rz --version 10:29:13

rz (lrzsz) 0.12.20

准备脚本

cd 到 /usr/local/bin 下，准备好 rz/sz 时需要执行的两个脚本：

$cd /usr/local/bin

$touchiterm2-send-zmodem.sh iterm2-recv-zmodem.sh

其中 iterm2-send-zmodem.sh 写入如下内容：

iterm2-send-zmodem.sh

#!/bin/bash

osascript -e 'tell application "iTerm2" to version' > /dev/null 2>&1 && NAME=iTerm2 || NAME=iTerm

if [[ $NAME = "iTerm" ]]; thenFILE=`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)&\"\")"`

elseFILE=`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 = "" ]]; thenechoCancelled.

# Send ZModem cancel

echo -e \\x18\\x18\\x18\\x18\\x18

sleep1

echo

echo \# Cancelled transfer

else

/usr/local/bin/sz "$FILE" -e -b

sleep1

echo

echo \# Received $FILE

fi

iterm2-recv-zmodem.sh 写入如下内容：

iterm2-recv-zmodem.sh

#!/bin/bash

# Author: Matt Mastracci (matthew@mastracci.com)

# AppleScript from http://stackoverflow.com/questions/4309087/cancel-button-on-osascript-in-a-bash-script

osascript -e 'tell application "iTerm2" to version' > /dev/null 2>&1 && NAME=iTerm2 || NAME=iTerm

if [[ $NAME = "iTerm" ]]; thenFILE=`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)&\"\")"`

elseFILE=`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 = "" ]]; thenechoCancelled.

# Send ZModem cancel

echo -e \\x18\\x18\\x18\\x18\\x18

sleep1

echo

echo \# Cancelled transfer

else

/usr/local/bin/sz "$FILE" -e -b

sleep1

echo

echo \# Received $FILE

fi

赋予脚本可执行权限

脚本准备好之后，需要通过 chmod 为其赋予可选择权限。

$sudo chmod777 /usr/local/bin/iterm2-*

配置 iTerm2

command + , 打开设置后依次进入 Profiles -> Default -> Advanced -> Triggers -> Edit，打开触发器的编辑界面。

依次添加两个触发器，配置如下：

Regular expression: rz waiting to receive.\*\*B0100

Action: Run Silent Coprocess

Parameters: /usr/local/bin/iterm2-send-zmodem.sh

Instant: checked

Regular expression: \*\*B00000000000000

Action: Run Silent Coprocess

Parameters: /usr/local/bin/iterm2-recv-zmodem.sh

Instant: checked
