GIT-STRIPSPACE(1)						    Git Manual							 GIT-STRIPSPACE(1)

NAME

       git-stripspace - Remove unnecessary whitespace

SYNOPSIS

       git stripspace [-s | --strip-comments] < input

DESCRIPTION

       Clean the input in the manner used by git for text such as commit messages, notes, tags and branch descriptions.

       With no arguments, this will:

       o   remove trailing whitespace from all lines

       o   collapse multiple consecutive empty lines into one empty line

       o   remove empty lines from the beginning and end of the input

       o   add a missing 
 to the last line if necessary.

       In the case where the input consists entirely of whitespace characters, no output will be produced.

       NOTE: This is intended for cleaning metadata, prefer the --whitespace=fix mode of git-apply(1) for correcting whitespace of patches or
       files in the repository.

OPTIONS

       -s, --strip-comments
	   Skip and remove all lines starting with #.

EXAMPLES

       Given the following noisy input with $ indicating the end of a line:

	   |A brief introduction   $
	   |   $
	   |$
	   |A new paragraph$
	   |# with a commented-out line    $
	   |explaining lots of stuff.$
	   |$
	   |# An old paragraph, also commented-out. $
	   |	  $
	   |The end.$
	   |  $

       Use git stripspace with no arguments to obtain:

	   |A brief introduction$
	   |$
	   |A new paragraph$
	   |# with a commented-out line$
	   |explaining lots of stuff.$
	   |$
	   |# An old paragraph, also commented-out.$
	   |$
	   |The end.$

       Use git stripspace --strip-comments to obtain:

	   |A brief introduction$
	   |$
	   |A new paragraph$
	   |explaining lots of stuff.$
	   |$
	   |The end.$
