How to use scp and ssh command in a same script? First I have to copy one file from my local server to remote. Then from local server itself, I have to check the size of the copied file.

  • What's the rationale for not being able to use SSH keys? Your Q really makes no sense, given you're using SCP and SSH. – slm Feb 7 '14 at 8:18
  • I'd recommend using rsync to handle the copy and checking with ssh as its backend, then set up a passwordless public/private authentication key for rsync to use. Keep the private key in a directory accessible only to the userid running the rsync script. Done. – Shadur Feb 7 '14 at 9:25

I would use public/private key to automate the conection without the need of using a password.

Yes, you need keys. Step 1. generate them At terminal (assuming CentOs/RHEL or similar): ssh-keygen (quick-shortcut - YES - to all)

Step 2. Put your public keys onto that remote server. Actually save yourself trouble and run the following: ssh-copy-id @

Done. You have your keys on the remote system now. Now you can test logging in without the password (password-free-access)

Test with: ssh @ If you get to login without any prompt for password. super.

Then you can just copy things over and do all those file size checks now : scp file.ext @:/some/location ; ssh @ "du /some/location/file.ext"
