Create aliases for working with remote clusters.

pssh-aliases.sh

#
# Dependencies (Debian): pssh, pdsh, cssh
#
# Under ~/.pssh/ I keep lists of hosts, one cluster per file, one hostname per line.
#

alias mssh='f() { hosts=$1; shift; for h in $(cat ~/.pssh/$hosts); do ssh $h $@ ; done }; f'

# auto-generate aliases for common host groups
for hostlist in $(ls ~/.pssh/); do
        for cmd in ssh scp rsync slurp nuke; do
                alias p$cmd-$hostlist="parallel-$cmd -h ~/.pssh/$hostlist"
        done
        alias pdsh-$hostlist="pdsh -w \$(tr \\\\n , < ~/.pssh/$hostlist)"
        alias cssh-$hostlist="cssh \$(tr \\\\n ' ' < ~/.pssh/$hostlist)"
        alias mssh-$hostlist="mssh $hostlist"
