First off, Thank you all for the knowledge I have gleaned from this site!
Deleting Records from a text file... sed paragraphs
The following code works nearly perfect, however each time it is run on the log file it adds a newline at the head of the file, run it 5 times, it'll have 5 blank lines at the head of the file.
I have been unable to figure out why or how to prevent it.
Newlines should be after the record, not before.
Also, How big of file can sed handle like this??
The code: (I have made it into a here doc for example)

I have
cat /etc/passwd | sed '/sh/!d' Which prints out all lines that have sh somewhere in it.
So I added $, which I thought matches the ends on lines, but its not working, like for example I have have... (5 Replies)

GIT-STRIPSPACE(1) Git Manual GIT-STRIPSPACE(1)NAME
git-stripspace - Remove unnecessary whitespace
SYNOPSIS
git stripspace [-s | --strip-comments]
git stripspace [-c | --comment-lines]
DESCRIPTION
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:
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.$
