If you put the git-all command provided in this gist as an executable in your PATH then:

For a structure like:

/just/a/project/group/path

• project-1/
• project-2/
• project-3/

Where project-{1,2,3} are all git directories we can execute the following:

mehiel

#!/bin/bash

set -e

database="MY_DATABASE"
altered_tables=0

function fatal {
  echo "FATAL: $1" >&2
  echo "Exiting now." >&2

mehiel

#!/bin/bash

function usage {
  echo "Use ./run_ghost.sh table_name 'alter_command' [other_ghost_args]"
  exit 1
}

database="MY_DATABASE_NAME"

table=$1

mehiel

#!/bin/bash

# "panic button" when run in a for loop:
# exit

database="MY_DATABASE"
export_dir="/mnt/backups/my-archive"

set -e
