           hosts file (each line "host[:port] [user]")

       -l --user
           username (OPTIONAL)

       -p --par
           max number of parallel threads (OPTIONAL)

       -o --outdir

       -e --errdir
           output directory for stderr files (OPTIONAL)

EXAMPLE

       The following example runs hostname on three machines (IPs or hostnames) specified in the
       file ips.txt using login irb2 and saves the output in /tmp/foo.

           # parallel-scp -h ips.txt -l irb2 /etc/hosts /tmp/hosts
           Success on 128.112.152.122:22
           Success on 18.31.0.190:22
           Success on 128.232.103.201:22

       following environment variables:

       •   PSSH_HOSTS
       •   PSSH_USER
       •   PSSH_PAR
