Can you scp a file to multiple locations in the same command?

For example:

scp file.txt,

Or would it be more practical to create a bash script that has all the hosts already in it and it would just take a file as the argument?

Let's say you have a file (destfile.txt) with user@host-values, one on each line. Then you could do like this:

for dest in $(<destfile.txt); do
  scp ourfile.txt ${dest}:remote/path/

This works! Still a handful to type out though. Perhaps there's a way to simplify that. – Andrew Sep 22 '11 at 21:02
@Andrew, if you change the for-loop into while read dest; do, it will read from standard input. Put it in a script and feed the destfile.txt into it (e.g., ./ <destfile.txt). – Kusalananda Sep 22 '11 at 21:19
Thank you. That does simplify it a bit. – Andrew Sep 22 '11 at 21:24

Looks like a job for parallel-scp - this implements a set of commands that allow for scp commands to be run on multiple systems at once. It will allow for the copying of files in parallel to a set of machines.

cat file.txt | tee >(ssh "cat > file.txt") \
                   >(ssh "cat > file.txt")

tar cz file1 file2 file3 | tee >(ssh "tar xz") \
                               >( ... )
