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 comment character (default #).
-c, --comment-lines
Prepend comment character and blank to each line. Lines will automatically be terminated with a newline. On empty lines, only the
comment character will be prepended.
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.$
