error
X=hello world
X = "hello world"
OK
X="hello world"
#output
echo $X

city=$1
if [ "$city" == "Ottawa" ]
then
echo "What a great city"
else
echo "Hello, you're in WordCamp $city!"
fi

#!/bin/bash
servers=( 'web1.example.com' 'web2.example.com' )

You can create scripts the run
scripts

for server in "${servers[@]}"; do
echo $server
scp ./wp-cli.phar user@$server:
ssh user@$server "chmod +x wp-cli.phar"
ssh user@$server "sudo mv wp-cli.phar /usr/local/bin/wp"
ssh user@$server "/usr/local/bin/wp --info"

--post_title="$page"
--post_author=$userID
--porcelain
echo "wp post create $page"
done
