You can simplify that a lot by knowing what statements before and after a code block do in awk.
The $1=="variableStep" before the code block tells it to run { $2 *= ratio } only when $1=="variableStep".
The 1 after the code block tells it to print every single line (even when $2 *= ratio isn't run). You could put any logical statement there but we put '1' so it's always true.
Before I even attempt this, is it possible to grep for a pattern, maybe a partial sentence like "go to page 3", assign that to a variable and then use awk or something to pull out the 3 and assign it to a variable? So first I would have
Gotopg = "go to page 3"
then
page = 3 (9 Replies)

RDIFF-BACKUP(1) User Manuals RDIFF-BACKUP(1)NAME
rdiff-backup-statistics - summarize rdiff-backup statistics files
SYNOPSIS
rdiff-backup-statistics [--begin-time time] [--end-time time] [--minimum-ratio ratio] [--null-separator] [--quiet] repository
DESCRIPTION
rdiff-backup-statistics reads the matching statistics files in a backup repository made by rdiff-backup and prints some summary statistics
to the screen. It does not alter the repository in any way.
The required argument is the pathname of the root of an rdiff-backup repository. For instance, if you ran "rdiff-backup in out", you could
later run "rdiff-backup-statistics out".
The output has two parts. The first is simply an average of the all matching session_statistics files. The meaning of these fields is
explained in the FAQ included in the package, and also at http://rdiff-backup.nongnu.org/FAQ.html#statistics.
The second section lists some particularly significant files (including directories). These files are either contain a lot of data, take
up increment space, or contain a lot of changed files. All the files that are above the minimum ratio (default 5%) will be listed.
If a file or directory is listed, its contributions are subtracted from its parent. That is why the percentage listed after a directory
can be larger than the percentage of its parent. Without this, the root directory would always be the largest, and the output would be
boring.
OPTIONS --begin-time time
Do not read statistics files older than time. By default, all statistics files will be read. time should be in the same format
taken by --restore-as-of. (See TIME FORMATS in the rdiff-backup man page for details.)
--end-time time
Like --begin-time but exclude statistics files later than time.
--minimum-ratio ratio
Print all directories contributing more than the given ratio to the total. The default value is .05, or 5 percent.
--null-separator
Specify that the lines of the file_statistics file are separated by nulls ( ). The default is to assume that newlines separate.
Use this switch if rdiff-backup was run with the --null-separator when making the given repository.
--quiet
Suppress printing of the "Processing statistics from session..." output lines.
BUGS
When aggregating multiple statistics files, some directories above (but close to) the minimum ratio may not be displayed. For this reason,
you may want to set the minimum-ratio lower than need.
