# cat file
# All empty lines with any combination of space characters should be ignored.
# need to ignore this line as well
one="1111111" # Anything after # should be ignored,, still keep line break.
two="22222222"
three=333333333 other data
# awk '$1!="#" && NF{gsub(/^[\t ]*/,x);sub("#.*",x);print}' file

My solution will remove any leading spaces or tab char preserving the rest of the record.
On the other hand Franklin52 solution will reformat($1==$1) the record replacing FS(space and/or tab char) by default OFS(single space char).
We have to convert a sequential file to a 80 char line sequential file (HP UX platform).The sequential file contains special characters. which after conversion of the file to line sequential are getting coverted into "new line" or "tab" and file is getting distorted. Is there any way to read these... (2 Replies)

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.$
