Sorry the at_engilsh was a typo. And it is an apache rewrite rule, though my question really doesn't pertain to the rewrite rule at all. The rules function just fine, the question is more just for operating on one iteration of the string and using awk to transform into the other iteration.

Yes this is exactly what I needed, thank you for your assistance and apologies for my less than stellar description of what I was looking for!

logcheck-test

logcheck-test(1)					      General Commands Manual						  logcheck-test(1)

NAME

       logcheck-test - test new logcheck rules easily

SYNOPSIS

       logcheck-test [-q|-i] [-a|-s|-l FILE] [-e] [-P PREFIX] [-S SUFFIX] RULE
       logcheck-test [-q|-i] [-a|-s|-l FILE] -r RULEFILE

DESCRIPTION

       logcheck-test  parses  a log file for matching lines specified by a single rule or a rule file. If using a single RULE you can set a PREFIX
       and a SUFFIX to write new rules easily.

OPTIONS

       -h, --help
	      Show usage information

       -a, --auth.log
	      Parse /var/log/auth.log for matching lines

       -s, --syslog
	      Parse /var/log/syslog for matching lines

       -l, --log-file FILE
	      Parse FILE for matching lines

       -i, --invert-match
	      Show line that don't match the RULE or the RULEFILE

       -q, --quiet
	      Suppress rule summary at the end of output

       -e, --surround-rule
	      Surround RULE with standard prefix and suffix:

	      ^[[:alpha:]]{3} [ :[:digit:]]{11} [._[:alnum:]-]+ RULE$

       -P, --append-prefix PREFIX
	      Append PREFIX to rule prefix. Option can be given multiple times

       -S, --prepend-suffix SUFFIX
	      Prepend SUFFIX to rule suffix. Option can be given multiple times

       -r, --rule-file RULEFILE
	      Use file RULEFILE for rule input

EXAMPLES

       With logcheck-test you can easily write and test new rules.

       Test a single rule against /var/log/syslog:
	      logcheck-test -s "RULE"

       Test a single rule against ~/log, surround the rule with standard prefix and suffix and append "kernel " to prefix:
	      logcheck-test -l ~/log -e -P "kernel " "RULE"

       Test the rules in rulefiles/linux/ignore.d.server/kernel against ~/log:
	      logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel

       Test which lines the rules in rulefiles/linux/ignore.d.server/kernel doesn't match:
	      logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel -i

EXIT STATUS

       On successful matching logcheck-test will complete with exit code 0. An exit code of 1 indicates no successful matching.

       An exit code greater then 1 indicates an error occurred. Textual errors are written to the standard error stream.
