Full Discussion: Ssh to an array of servers in a for loop
Top Forums Shell Programming and Scripting Ssh to an array of servers in a for loop Post 302852803 by Corona688 on Thursday 12th of September 2013 12:26:57 PM

A construct I often use:

Code:
ssh username@host exec sh -s -- "arg1" "arg2" "arg3" <<"EOF"

# Literal, unescaped script contents to be executed on the remote side.

echo "arg1 is $1"
echo "arg2 is $2"
echo "arg3 is $3"

# The EOF must be at the beginning of the line and not indented.
EOF
