MigBash

Simple way to accumulate and use bash utilities

Just provide -h parameter to show help info

#!bash

$ ./migbash -h
Usage:
      ./migbash [-m] [-h]
      ./migbash [module_name] [module_method] [options]...

Obviously one can use short form, just type:

#!bash

$ mv ./migbash.sh mb

and then use it:

#!bash

$ ./mb -h or whatever

Use -m parameter to show list of available modules with methods/submodules:

#!bash

$ ./migbash.sh -m

modules list

You can simply use listed modules e.g.:

#!bash

$ ./migbash.sh db backup
$ ./migbash.sh wp add_user
$ ./migbash.sh migrate migrate
etc...

How to create simple module:

Go to migbash/modules folder. Feel free to create new folder if it's necessary or use existing one. Let's create new folder, it will be your module's name:

#!bash

$ mkdir foobar

Create file, e.g. my_module: touch my_module Write down next strings:

#!bash

showme() {
    echo "Hello from My module!"
}

Go to the folder where migbash.sh is placed:

#!bash

$ cd ../../

Run your module:

#!bash

$ ./migbash.sh foobar showme

As a result you'll see the string:

#!bash

Hello from My module!

Add the following method into your module:

#!bash

my_module_help() {
    echo -e "$(MigBash::color showme cyan black)$(MigBash::margin 16) – My first module ShowMe"
}

Now if you type $ ./migbash -m you will see simple info about your module:

MigBash modules list

MigBash internal methods:

Using MigBash::getVal paramName method you can retrieve value for provided parameter from a configuration file

#!bash

# path to config file
local settings='modules/'${module}'/db.ini'
local db_user=$(MigBash::getVal db_user ${settings})
local db_pass=$(MigBash::getVal db_pass ${settings})
local config_path=$(MigBash::getVal path ${settings})

And here is an example of db.ini configuration file:

#!bash

[backup]
db_user=user
db_pass=pass
db_host=127.0.0.1
db_port=3306
path=/home/path/to/smth/

You can use MigBash::color function to colorize output:

MigBash::color 'some text' foreground_color background_color

#!bash

$(MigBash::color showme cyan black)

For the moment available colors are: black, red, green, yellow, blue, magenta, cyan, white

Also you can use MigBash::margin function to make margins for your text:

next call will shift the text position into 16 points

#!bash

MigBash::margin 16

Some examples:

Using db backup module

You can make database backup with this command:

#!bash

$ ./migbash.sh db backup your_db_name /path/to/save/backup

Or you can just call:

#!bash

$ ./migbash.sh db backup

and make a backup via simple dialog:

MigBash db backup

Path to place database backup:

MigBash db backup

The same way you can use , e.g. wordpress modules:

#!bash

$ ./migbash.sh wp add_user
$ ./migbash.sh wp change_domain
etc...

Or you can provide parameters to the modules if you don't want to use dialogs
