Full Discussion: Problem with While Loop in AIX Server

AIX 5.3 has ksh93, but I don't have it anymore and can't say right now how "fresh" ksh93 there.

Code:
awk '
$1 == "EFFECTIVE_TIME" {
  print "printf \"EFFECTIVE_TIME %T\n\" \\#"$2
  }  

$1 != "EFFECTIVE_TIME" {
  print "print "$0
  }' $TMP

According to your script you're interested only in the strings which begin with EFFECTIVE_TIME as the 1st word. In awk we have 2 statements - the first statement is for the strings, which have EFFECTIVE_TIME as the 1st word, and the second statement is for all other strings.

In the second case (easiest case) we just print the string itself. It is usually done with print $0.

In the first case we have to transform UNIX seconds to "normal" representation of the date. AIX standard awk doesn't have function to work with time/date as GNU awk, but ksh93 has.

So based on the input data we form a new script, which will be executed by ksh and transforms timestamp. If you run the one-line without | ksh93, you will see the script written with awk. Something like:

Code:
$ awk '$1 == "EFFECTIVE_TIME" {print "printf \"EFFECTIVE_TIME %T\n\" \\#"$2} $1 != "EFFECTIVE_TIME" {print "print "$0}' t1
print ACTIVE 1
printf "EFFECTIVE_TIME %T
" \#1279345218
print GRANULAR_RESTORE_INFO 0
print

With this last part | ksh93 we just say, that the script should be executed by ksh93.

There is an easier way without awk:
Code:
cat t1 | while read A rest ; do [ "$A" == "EFFECTIVE_TIME" ] && printf "EFFECTIVE_TIME %T\n" \#$rest  || print -- "$A $rest" ; done

but in this case you will loose spaces between first word and the rest of the data, if you have more than 1 space character.

test::script

Test::Script(3) 					User Contributed Perl Documentation					   Test::Script(3)

NAME

       Test::Script - Basic cross-platform tests for scripts

DESCRIPTION

       The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or
       bin as is also commonly used) paths of your Perl distribution.

       Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible.

       That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is
       considered unacceptable.

       In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking
       that your module won't on some platform because of the dependency.

       Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform
       safety.

FUNCTIONS

   script_compiles
	   script_compiles( 'script/foo.pl', 'Main script compiles' );

       The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error.

       The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the
       local name used will be shown in the diagnostic output.

       Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl).
       This will also be shown in the diagnostic output on failure.

   script_runs
	   script_runs( 'script/foo.pl', 'Main script runs' );

       The "script_runs" test executes the script with "perl script.pl" and checks that it returns success.

       The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the
       local name used will be shown in the diagnostic output.

       The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also
       be shown in the diagnostic output on failure.
