PARALLEL-SCP(1) 														   PARALLEL-SCP(1)

NAME

       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:

       o   PSSH_HOSTS
       o   PSSH_USER
       o   PSSH_PAR
       o   PSSH_OUTDIR
       o   PSSH_VERBOSE
       o   PSSH_OPTIONS

NAME

     scp -- secure copy (remote file copy program)

SYNOPSIS

     scp [-pqrvBC46] [-F ssh_config] [-S program] [-P port] [-c cipher] [-i identity_file] [-o ssh_option] [[user@]host1:]file1 [...]
	 [[user@]host2:]file2

DESCRIPTION

     scp copies files between hosts on a network.  It uses ssh(1) for data transfer, and uses the same authentication and provides the same secu-
     rity as ssh(1).  Unlike rcp(1), scp will ask for passwords or passphrases if they are needed for authentication.

     Any file name may contain a host and user specification to indicate that the file is to be copied to/from that host.  Copies between two
     remote hosts are permitted.

     The options are as follows:

     -c cipher
	     Selects the cipher to use for encrypting the data transfer.  This option is directly passed to ssh(1).

     -i identity_file
	     Selects the file from which the identity (private key) for RSA authentication is read.  This option is directly passed to ssh(1).

     -p      Preserves modification times, access times, and modes from the original file.

     -r      Recursively copy entire directories.

     -v      Verbose mode.  Causes scp and ssh(1) to print debugging messages about their progress.  This is helpful in debugging connection,
	     authentication, and configuration problems.

     -B      Selects batch mode (prevents asking for passwords or passphrases).

     -q      Disables the progress meter.

     -C      Compression enable.  Passes the -C flag to ssh(1) to enable compression.

     -F ssh_config
	     Specifies an alternative per-user configuration file for ssh.  This option is directly passed to ssh(1).

     -P port
	     Specifies the port to connect to on the remote host.  Note that this option is written with a capital 'P', because -p is already
	     reserved for preserving the times and modes of the file in rcp(1).

     -S program
	     Name of program to use for the encrypted connection.  The program must understand ssh(1) options.

     -o ssh_option
	     Can be used to pass options to ssh in the format used in ssh_config(5).  This is useful for specifying options for which there is no
	     separate scp command-line flag.  For example, forcing the use of protocol version 1 is specified using scp -oProtocol=1.

     -4      Forces scp to use IPv4 addresses only.

     -6      Forces scp to use IPv6 addresses only.

DIAGNOSTICS

     scp exits with 0 on success or >0 if an error occurred.
