4. install rz sz Upload and download

mac Upper use brew install lrzsz

brew install lrzsz

Linux Upper use yum install lrzsz

yum install -y lrzsz

stay mac Create two scripts on

cd /usr/local/bin

rz : Upload

# stay bash in , That is to say iTerm2 The input terminal rz  The file selection box will pop up , Select File  choose  Start uploading , Will be uploaded to the current directory 
rz

 Be careful ： Alone with rz There will be two questions ： Upload interrupted 、 Upload file changes （md5 Different ）, The solution is to upload rz -be, And remove the pop-up dialog box “Upload files as ASCII” Check before .
-a, –ascii
-b, –binary  use binary The way to upload and download , Do not interpret characters as ascii
-e, –escape  mandatory escape  All control characters , such as Ctrl+x,DEL etc. 
rar,gif And other documents  -b  use binary Way to upload .

 If the file is large and the upload error occurs , Using parameters  -e
 If you use... Without parameters rz When the command uploads a large file , It is often broken in the middle of uploading , Probably rz It is assumed that the uploaded stream contains some special control characters , cause rz Exit ahead of time .

 Sum up , Please use  rz  -be

sz : download

#sz fileName( The name of the file you want to download )  enter , A window will pop up   We can choose the place to save .
sz aaa.txt

5. solve No such file or directory

Use rz perhaps sz This error occurred after

/usr/local/bin/iterm2-send-zmodem.sh: line 17: /usr/local/bin/sz: No such file or directory

as a result of :

Because we use brew install lrzsz, Our script cannot be found in the current directory lrzsz

lrzsz The installation directory can be viewed in this way

brew list lrzsz

/opt/homebrew/Cellar/lrzsz/0.12.20_1/share/man/ (2 files)

The key is these two

/opt/homebrew/Cellar/lrzsz/0.12.20_1/bin/rz
/opt/homebrew/Cellar/lrzsz/0.12.20_1/bin/sz

There are two solutions

Mode one : Create a soft connection

stay /usr/local/bin/ Create a soft connection in the directory

sudo ln -s /opt/homebrew/Cellar/lrzsz/0.12.20_1/bin/rz  /usr/local/bin/rz

sudo ln -s /opt/homebrew/Cellar/lrzsz/0.12.20_1/bin/sz  /usr/local/bin/sz

Mode two : Modify the configuration file

modify 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)&\"\")")

if [[ $FILE = "" ]]; then
    echo Cancelled.
    # Send ZModem cancel
    echo -e \\x18\\x18\\x18\\x18\\x18
    sleep 1
    echo
    echo \# Cancelled transfer

    sleep 1
    echo
    echo
    echo \# Sent \-\> $FILE
fi

** modify 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

6. Solve the problem of using expect After automatic login , Out of commission rz and sz The question of orders

take Mac The local LC_CTYP The environment variable is set to en_US

# Direct modification is not recommended , Create a script , Execute... In a script 
vim aliecs1.sh

#!/bin/sh
# take Mac The local LC_CTYP The environment variable is set to en_US, The solution can't be  rz  The problem of 
export LC_CTYPE=en_US
# This is you expect Script for automatic login 
/Users/zhangzhiyuan/ssh/aliecs.sh

take Iterm2 there aliecs.sh Change to aliecs1.sh
