parallel-scp - parallel versions of scp

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:

•PSSH_HOSTS

•PSSH_USER

•PSSH_PAR

•PSSH_OUTDIR

•PSSH_VERBOSE
