I would like to scp multiple files to a remote server that requires a password for the process to be completed.
I have 30 folders (x_1, x_2 ... x_30), each containing 25 files. What I want to do is scp 1 out of the 25 files (file called bvals) for all my folders to a remote server and place each file to its respective folder (x_1, x_2 ... x_30 in the remote server).
I wrote this script:
Code:
for n in x_1 x_2 x_3 x_4 x_5 x_6 x_7 x_8 x_9 x_10 x_11 x_12 x_13 x_14 x_15 x_16 x_17 x_18 x_19 x_20 x_21 x_22 x_23 x_24 x_25 x_26 x_27 x_28 x_29 x_30
do
scp $HOME/data/${n}/bvals remote_server@remote.edu:/me/my_data/${n}
done
The problem with this script (of course) is that every time n takes a new argument (x_1 etc) I am asked to insert my password.
Is there any way to write this script in a way such that I am prompted to write my password only once?
Thank you!

Hi.
I'm trying to speed up an rsync command by running it in parallel. There's no real option for this other than if the files are in multiple directories (which they're not).
