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 SEE ALSO
