SYNOPSIS

       parallel-scp [OPTIONS] -h hosts.txt local remote

DESCRIPTION

       pssh provides a number of commands for executing against a group of computers, using SSH. It's most useful for operating on clusters of
       homogenously-configured hosts.

       parallel-scp copy files in parallel to a set of machines.

OPTIONS

       -r --recursive
	   recusively copy directories (OPTIONAL)

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

       -l --user
	   username (OPTIONAL)

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

       -o --outdir
	   output directory for stdout files (OPTIONAL)

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

       -t --timeout
	   timeout (secs) (-1 = no timeout) per host (OPTIONAL)

       -O --options
	   SSH options (OPTIONAL)

       -v --verbose
	   turn on warning and diagnostic messages (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

ENVIRONMENT

       All four programs take similar sets of options. All of these options can be set using the following environment variables:

       o   PSSH_HOSTS
       o   PSSH_USER
       o   PSSH_PAR
