Methods for removing redundant interactive prompts from mget in ftpshell scripts

By default, interactive prompts in FTP are enabled. This prompt is annoying when multiple files are downloaded, if multiple mget files are to be written from the FTP server in the shell script, it is very troublesome to write an interactive script. it is best to turn off the interactive prompt.
After entering the FTP command, prompt will reverse the configuration of the interactive prompt. If the original interactive prompt is on, it will be closed after prompt is used. If it was originally disabled, then use prompt to open it. of course, you can also directly add parameters such as prompt on or prompt off.
