Simple default-safe rsync deployment script

deploy.sh

#!/bin/bash

# Will add --dry-run unless the --go option is set. All other arguments passed to rsync (e.g. --delete)
SOURCE=.
DEST=example.com:/var/www/mysite

DRYRUN="--dry-run"
args=()

for var in "$@"
do
    if [ $var == "--go" ]
    then
        DRYRUN=""
    else
        args=( "${args[@]}" "$var" )
    fi
done

/usr/bin/env rsync -azCcO --force --progress --exclude-from=rsync_exclude.txt $DRYRUN "${args[@]}" "$SOURCE" "$DEST"

Obviously this is for relatively simple deployments. At the other end of the scale, Capifony is a powerful Ruby-based configurable solution for managing Symfony & Symfony2 deployments to multiple servers and can do stuff like provide atomic, reversible deployments, and run scripts (like database migrations, Composer update, or your test suite). If that's too complicated and this script is too simple, Anchour may suit you better.
