Linux, Can you scp a single file to multiple locations

Question

Can you scp a file to multiple locations in the same command?
IE. scp file.txt user@ip-1.com:, user@ip2.com:

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?

Answer 1

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/
done

Answer 2

cat file.txt | tee >(ssh user@ip1.com "cat > file.txt") \
                   >(ssh user@ip2.com "cat > file.txt")

tar cz file1 file2 file3 | tee >(ssh user@ip1.com "tar xz") \
                               >( ... )
