We realize that the tab key is broken on your keyboard and you don't care about being able to see the structure of your code by properly indenting it. So, yes, the above code will be accepted by your shell.

But, some day, perhaps years from now when you have to look at your code again when something needs to be changed, you'll realize that programming style does make a difference and if statements should be indented when they appear inside a loop and statements in then and else clauses in if statements should be indented further.

Code:
	if ! tar cf "${DIR}".tar "${DIR}"
	then	mail -s "tar failed $DIR" $MailAddress <<< "creating of tar $DIR failed due to error, removing $DIR.tar"
		rm -f "$DIR".tar
		continue
	fi

MM-COMMON-PREPARE(1)						  mm-common 0.9.5					      MM-COMMON-PREPARE(1)

NAME
mm-common-prepare - Prepare a C++ binding module to use mm-common SYNOPSIS
mm-common-prepare [OPTION]... [SOURCE-DIR] DESCRIPTION
Run mm-common-prepare to install the mm-common build support files into the source tree of a C++ binding module. The exact location where these files will be installed can be influenced through special macros in the configure.ac file. AC_CONFIG_AUX_DIR([AUX-DIR]) The Automake include files are placed into the AUX-DIR subdirectory of the top-level source directory. If AC_CONFIG_AUX_DIR is not specified, the files are placed at the top-level of the module's source tree. MM_CONFIG_DOCTOOL_DIR([DOCTOOL-DIR]) If the MM_CONFIG_DOCTOOL_DIR macro is called with an explicit DOCTOOL-DIR argument, the common utilities required for generating and installing the reference documentation of a C++ binding module will be installed into the named subdirectory. If MM_CONFIG_DOC- TOOL_DIR is not used or does not specify a DOCTOOL-DIR argument, mm-common-prepare will not install the documentation utility files into the module's source tree. Instead, it is assumed that the module depends on glibmm and can use the installed documentation utilities that come with it. If no SOURCE-DIR argument has been specified on the command line, the current working directory will be used. OPTIONS
-c, --copy copy files instead of creating symbolic links to them -f, --force forcefully replace existing files or symbolic links --help display a help message and exit --version show version information and exit EXIT STATUS
The exit status is 0 if OK, or 1 if an error occurred. FILES
The build support files currently installed by mm-common-prepare are listed below. Automake include files installed into AUX-DIR: compile-binding.am dist-changelog.am doc-reference.am generate-binding.am Documentation utilities installed into DOCTOOL-DIR: doc-install.pl doc-postprocess.pl doxygen.css tagfile-to-devhelp2.xsl SEE ALSO
autoreconf(1) /usr/share/doc/mm-common/README /usr/share/doc/mm-common/skeletonmm.tar.gz GNOME
