Top Forums UNIX for Advanced & Expert Users Need help to delete special characters exists only at the end of the each record in UNIX file? Post 303030210 by Don Cragun on Thursday 7th of February 2019 05:49:53 AM

Hi Rakesh,
You say that the letter M at the end of each input line is special and has to be removed. The letter M can't be removed if you say it is not special. We can't possibly meet your requirements if your requirements are inconsistent.

If you want to change your requirements to only remove sequences of characters that are not a space character and that are not alphanumeric characters from the end of each input line, the output produced from your sample input will be identical to the input because the last character is an alphanumeric character!

You had several suggestions earlier that, among many other things, removed all non-alphanumeric characters from the end of field 15 or from the end of the input record and you rejected all of them because they didn't get rid of trailing M.

I give up!

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.$ GIT
Part of the git(1) suite Git 2.17.1 10/05/2018 GIT-STRIPSPACE(1)
