### raguel

Mythological Context: http://en.wikipedia.org/wiki/Raguel_(archangel)
Reference: ArchAngel, Name means The friend of God.

It's here to be the friend of Shell Gods to create minion scripts to serve
the SYSTEMS.

For ways it can improve Shell Scripting, refer Wiki.

It's best suited to Bourne Shell,
though it's made compatible to others as much possible.

* Loop a given command run for given count
```Shell
  repeat_run $TIMES_TO_REPEAT "$COMMAND_TO_RUN"
```

#### [Git](https://github.com/abhishekkr/raguel/blob/master/doc/git.md)

* Set Env Var RAGUEL_GIT_LOCAL_SHA to latest Local SHA in Current DIR
```Shell
  local_sha
```

* Set Env Var RAGUEL_GIT_REMOTE_SHA to latest Remote SHA in Current DIR
```Shell
  remote_sha
```

#### [Configurator](https://github.com/abhishekkr/raguel/blob/master/doc/configurator.md)

* Non-Interactive Package Manager
```Shell
  auto_install $PackageName

> auto_install, auto_uninstall
```

* Info ENV Var for Distro
```Shell
  $RAGUEL_DISTRO_TYPE : telling what distro family is RHEL, Debian, etc.
 
  $RAGUEL_PACKAGE_INSTALL : setting the auto-install command here

$RAGUEL_PACKAGE_UNINSTALL : setting the auto-uninstall command here

$RAGUEL_NODENAME : the nodename grabbed from uname goes here

$RAGUEL_ARCH : architecture information grabbed from uname goes here
```

#### [Checker](https://github.com/abhishekkr/raguel/blob/master/doc/checker.md)

```Shell
  All the checkers have if_{check}, then_if_{check}, else_if_{check}, if_not_{check}, then_if_not_{check}, else_if_not_{check}
```

```Shell
  So every check has a negation check version. And they both have then_, else_ checks for enabling chaining of checks as in get &&, || boolean functionality among checks.
```

* then_run , else_run , end_if
```Shell
  Every check can have following command on same line to run if check passes. Otherwise use then_run, else_run in combination with any check. It also provides 'end_if' to explicitly close Check block and make look good.
```

##### The example shown for if_equal can be used in permutation/combination with any other checks.

* Check for equality of 2 arguments
```Shell
  if_equal $ARG1 $ARG2 "$CMD_IF_PASSED"

if_equal $ARG1 $ARG2
  then_run "$CMD_IF_PASSED"

if_equal $ARG1 $ARG2
  else_run "$CMD_IF_FAILED"

if_equal $ARG1 $ARG2
  then_run "$CMD_IF_PASSED"
  else_run "$CMD_IF_FAILED"

if_equal $ARG1 $ARG2
  then_run "$CMD_IF_PASSED"
  else_run "$CMD_IF_FAILED"
  end_if

if_equal $ARG1 $ARG2
  then_if_equal $ARG3 $ARG4
  then_if_equal $ARG5 $ARG6
  then_run "$CMD_IF_PASSED_1"
  else_if_equal $ARG7 $ARG8
  then_run "$CMD_IF_PASSED_2"
  else_run "$CMD_IF_FAILED"
