I'm working as a programmer at the moment, and as a result need to constantly upload my software to remote systems for testing. I have about 7 machines which need to receive copies of everything.
At the moment, I have a short bash script with a scp performing the transfer for each remote machine:
echo -e "\nUpdating Taiwan Machine"
scp {file1,file} bschlinker@taiwan:/home/bschlinker/
echo -e "\nUpdating Wisconsin Machine"
scp -P 2400 {file1,file2} bschlinker@wisconsin:/home/bschlinker/
I'm painfully prompted for the password to each machine. I recognize I can solve this with SSH keys — but I don't want to have passwordless authentication to the remote machines via the key. As a result, I have a passphrase set on my SSH key. I read that after entering your passphrase once, it will remain active for the rest of the current terminal session. Is that true? If not, any ideas?

If you have a SSH agent running (such as the cleverly-named
ssh-agent) then you can add the key to the agent and the SSH client will communicate with the agent to get the key from it.
