git-stripspace - Man Page

• Trim whitespace from a file: cat path/to/file | git stripspace
• Trim whitespace and Git comments from a file: cat path/to/file | git stripspace [-s|--strip-comments]
• Convert all lines in a file into Git comments: git < path/to/file stripspace [-c|--comment-lines]

tldr.sh

git stripspace [-s | --strip-comments]
git stripspace [-c | --comment-lines]

Read text, such as commit messages, notes, tags and branch descriptions, from the standard input and clean it in the manner used by Git​.

With no arguments, this will:

• remove trailing whitespace from all lines
• collapse multiple consecutive empty lines into one empty line
• remove empty lines from the beginning and end of the input
• add a missing \n 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​.

-s,  --strip-comments

Skip and remove all lines starting with a comment character (core​.commentChar, default #)​.

-c,  --comment-lines

Prepend the comment character and a blank space to each line​. Lines will automatically be terminated with a newline​. On empty lines, only the comment character will be prepended​.

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​.$
