Top Forums Shell Programming and Scripting Need assistance with appending strings using sed and variables Post 302235255 by mandriver on Thursday 11th of September 2008 12:53:43 PM

Thanks guys for your replies, but unfortunately it's still not writing the string to the end of the file.

It gets past the parser, and the rest of the script executes without problem, but no string on the end of my incomplete line.

Perhaps I didn't do a good job of explaining the problem:

1) My file has x amount of lines
2) One of these lines will have a string missing from the end of it
3) I have the string that needs to be appended to this line, stored as a variable $string
4) I want sed to locate the line with a missing end, the end is in format *T00:00:00
5) If it finds a line that doesn't have an ending matching *T00:00:00, it needs to append $string to this line.

Any further help will be greatly appreciated.

many thanks

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.$ GIT
