If you are looking for a way to automate SFTP transfers in a shell script, then this article is for you. We will show you how to use the expect command to automate SFTP tasks in a shell script. Expect is a tool for automating interactive applications such as SFTP, FTP, Telnet, SSH, etc.
The expect command waits for the user to enter a specific string of characters. It then sends the specified string to the program. In this way, you can automate any interactive application.
The following is a simple expect script that automates the SFTP task of downloading a file from a remote server.
# Connect to remote server
spawn sftp user@remote_server
# Wait for password prompt
# Send password
# Wait for sftp prompt
# Send get command
send “get file_to_download.txt\r”
# Wait for download to complete
In the above script, we first connect to the remote server using the spawn command. We then wait for the password prompt and send the password. Next, we wait for the sftp prompt and send the get command to download the file. Finally, we exit the SFTP session.
You can also use the expect command to automate other tasks such as uploading files, changing directories, etc.
