Bash functions I found useful when working with multiple vagrant projects.

vagrant_aliases.sh

_vagrant_dirnames() {
	if [[ $COMP_CWORD > 1 ]]; then
		COMPREPLY=()
		return 1
	fi
	local cur="${COMP_WORDS[COMP_CWORD]}"
	pushd ~/vagrant/ > /dev/null
	local opts=( $cur*/ )
	popd > /dev/null
	if [[ "$opts" == "$cur*/" ]]; then
		COMPREPLY=()
		return 1
	fi
	COMPREPLY=( ${opts[@]%*/} )
	return 0
}

# Change to a vagrant dir
v() {
	local DIRNAME=$1
	if [ -z $DIRNAME ]; then
		cd ~/vagrant/
		return
	fi
	if [ ! -d ~/vagrant/$DIRNAME ]; then
		echo "No such vagrant dir: $DIRNAME"
	fi
	cd ~/vagrant/$DIRNAME
}

# Execute a vagrant command in a vagrant dir
va() {
	local DIRNAME=$1
	if [ ! -z $DIRNAME ]; then
		if [ -d ~/vagrant/$DIRNAME ]; then
			shift
			pushd ~/vagrant/$DIRNAME > /dev/null
		else
			DIRNAME=""
		fi
	fi
	vagrant $@
	if [ ! -z $DIRNAME ]; then
		popd > /dev/null
	fi
}

# Execute "vagrant up" in a vagrant dir
vu() {
	local DIRNAME=$1
	if [ ! -z $DIRNAME ]; then
		if [ ! -d ~/vagrant/$DIRNAME ]; then
			echo "No such vagrant dir: $DIRNAME"
			return
		fi
		pushd ~/vagrant/$DIRNAME > /dev/null
	fi
	vagrant up && vagrant ssh
	if [ ! -z $DIRNAME ]; then
		popd > /dev/null
	fi
}

# Bash completion ftw
complete -F _vagrant_dirnames v va vu

Some helpful bash functions for working with vagrant. These assume your vagrant instances live in direct subfolders of ~/vagrant/.

v [<dirname>]

cd to a vagrant dir with the given name.

va [<dirname>] <action>

Executes the given vagrant action in a vagrant dir with the given name or the current directory.

vu [<dirname>]

Calls vagrant up for a given vagrant instance (or in the current directory), then vagrant sshs into it
