since the file names have a specific format you can try this

Code:
for((i=6;i<=23;i++));
 do
 if  [-e rm1.txt];
 then 
grep "|" SRMR_$i.txt >> rm1.txt;
 else
 grep "|" SRMR_$i.txt > rm1.txt;
 fi;
 done

and more over when the file does not exist the append mode will simply open the file. so you can even skip the exist check

Code:
for((i=6;i<=23;i++));
 do
 grep "|" SRMR_$i.txt >> rm1.txt
 done

HTH,

NAME

       Test::LectroTest::RegressionTesting - How to do regression testing (for free!)

SYNOPSIS

	   use Test::LectroTest
	       regressions => "regressions.txt";

	   # -- OR --

	   use Test::LectroTest
	       playback_failures => "regression_suite_for_my_module.txt",
	       record_failures	 => "failures_in_the_field.txt";

	   # -- OR --

	   use Test::LectroTest::Compat
	       regressions => "regressions.txt";

	   # -- OR --

	   use Test::LectroTest::Compat
	       playback_failures => "regression_suite_for_my_module.txt",
	       record_failures	 => "failures_in_the_field.txt";

DESCRIPTION

       Say that LectroTest uncovers a bug in your software by finding a random test case that proves one of your properties to be false.  If you
       apply a fix for the bug, how can you be sure that LectroTest will re-test the property using the exact same test case that "broke" it
       before, just to be certain the bug really is fixed?  And how can you be sure that future changes to your code will not reintroduce the same
       bug without your knowing it?

       For situations like these, LectroTest can record failure-causing test cases to a file, and it can play those test cases back as part of its
       normal testing strategy.

       The easiest way to take advantage of this feature is to set the regressions parameter when you "use" Test::LectroTest or
       Test::LectroTest::Compat:

	   use Test::LectroTest
	       regressions => "regressions.txt";

       This tells LectroTest to use the file "regressions.txt" for both recording and playing back failures.  If you want to record and play back
       from separate files, use the record_failures and playback_failures options:

	   use Test::LectroTest::Compat
	       playback_failures => "regression_suite_for_my_module.txt",
	       record_failures	 => "failures_in_the_field.txt";

       Here is how it works:

       1.  When testing a property named N, LectroTest will check for a play-back file.  If the file exists, LectroTest will search it for test
	   cases associated with N.  If any such test cases exist, LectroTest will play them back before and in addition to performing the usual,
	   random testing of the property.

       2.  When performing the usual, random testing of a property named N, if a failure occurs (i.e., LectroTest finds a counterexample),
	   LectroTest will record the test case that caused the failure to the recording file, associating the test case with the name N.

       NOTE: If you pass any of the recording or playback parameters to Test::LectroTest::Compat, you must have version 0.3500 or greater of
       Test::LectroTest installed.  (Module authors, update your modules' build dependencies accordingly.)  The Test::LectroTest module itself,
       however, has always ignored unfamiliar parameters, and thus these options are backward compatible with older versions.

SEE ALSO

       Test::LectroTest gives a quick overview of automatic, specification-based testing with LectroTest.  This module accepts failure recording
       and play-back options.

       Test::LectroTest::Compat lets you mix LectroTest with the popular family of Test::Builder-based modules such as Test::Simple and
       Test::More. This module accepts failure recording and play-back options.
