Run sftp command with password in Bash script: Step-by-step
If you're looking to run an sftp command with a password in a Bash script, there are several steps you'll need to follow to get it up and running. Here's a step-by-step guide to help you get started.
Step 1: Install Expect
Expect is a scripting language that allows you to automate interactions with command-line programs. You'll need to install it before you can run sftp with a password in your Bash script.
To install Expect on Ubuntu or Debian, run the following command:
sudo apt-get install expect
On CentOS or Fedora, use this command instead:
sudo yum install expect
Step 2: Create an Expect script
Next, you'll need to create an Expect script that will input your password when prompted by sftp. Here's an example script:
#!/usr/bin/expect -f spawn sftp firstname.lastname@example.org expect "password:" send "YourPasswordHerer" interact
Replace "email@example.com" with your own sftp server address, and "YourPasswordHere" with your actual password.
Save this script as "sftp_expect.sh" (or whatever name you prefer) in the same directory as your Bash script.
Step 3: Modify your Bash script
Now it's time to modify your Bash script to include the Expect script. Here's an example:
#!/bin/bash ./sftp_expect.sh & sftp -b sftp_commands.txt firstname.lastname@example.org
This script runs the Expect script in the background, then runs the sftp command with a batch file ("sftp_commands.txt") that contains the commands you want to execute on the server.
Step 4: Run your Bash script
Finally, you can run your Bash script and it should automatically input your password when prompted by sftp. Here's how to do it:
chmod +x your_bash_script.sh ./your_bash_script.sh
And that's it! With these steps, you should now be able to run an sftp command with a password in your Bash script.
