How to use expect inside bash script
提问by Hasan Rumman
Could anybody please tell me why this is not working?
谁能告诉我为什么这不起作用？
#!/bin/bash
cd /home
touch somefile
/usr/bin/expect<<FILETRANSFER
spawn scp -r -P remoteServerPort somefile remoteServerIP:/home
expect "assword:"
send "MyPassWord\r"
interact
FILETRANSFER
echo "It's done"
It doesn't give any error but file is not transferred to remote server.I have tried many ways still couldn't find any solution.
它没有给出任何错误，但文件没有传输到远程服务器。我尝试了很多方法仍然找不到任何解决方案。

The bash script you have defined is passing the expect commands on the standard input of expect. However, the expectcommand requires its arguments on a file or as an argument using the -coption.
您定义的 bash 脚本在expect. 但是，该expect命令需要将其参数放在文件上或作为使用该-c选项的参数。
You have several options but to add the less modifications on your script you just need to use the process substitution to create a here-document (temporary) for the expectcommand.
您有多种选择，但要对脚本添加较少的修改，您只需要使用进程替换来为expect命令创建此处的文档（临时）。
#!/bin/bash
echo "[DEBUG] INIT BASH"
cd /home
touch somefile
/usr/bin/expect <(cat << EOF
spawn scp -r -P remoteServerPort somefile remoteServerIP:/home
expect "Password:"
send "MyPassWord\r"
interact
EOF
)
echo "[DEBUG] END BASH"
