I'm writing a script which word counts the number of lines in two files. If one file is bigger than the other I'd like to edit one of the files to delete some lines to make both the same. It does not matter where in the file the lines are deleted from. It's expected that this will be ran from crontab in root. I'm trying to use sed to do this but am having problems with passing the variable number of lines to delete. Can anyone help?
To use a shell variable in a sed command, use double quotes rather than single quotes:

editdiff
REDIFF(1) Man pages REDIFF(1)NAME
rediff, editdiff - fix offsets and counts of a hand-edited diff
SYNOPSIS
rediff ORIGINAL EDITED
rediff EDITED
rediff {[--help] | [--version]}
editdiff FILE
editdiff {[--help] | [--version]}
DESCRIPTION
You can use rediff to correct a hand-edited unified diff. Take a copy of the diff you want to edit, and edit it without changing any
offsets or counts (the lines that begin "@@"). Then run rediff, telling it the name of the original diff file and the name of the one you
have edited, and it will output the edited diff file but with corrected offsets and counts.
A small script, editdiff, is provided for editing a diff file in-place.
The types of changes that are currently handled are:
o Modifying the text of any file content line (of course).
o Adding new line insertions or deletions.
o Adding, changing or removing context lines. Lines at the context horizon are dealt with by adjusting the offset and/or count.
o Adding a single hunk (@@-prefixed section).
o Removing multiple hunk (@@-prefixed sections).
Alternatively, if only one argument is provided, it is taken to be the edited file and the counts and offsets are adjusted as appropriate.
Some assumptions are made when used in this mode. See recountdiff(1) for more information.
