Pass parameters to a function and running functions in parallel
Hi ,

I have a script which is using a text file as I/P.
I want a code where it reads n lines from this file and pass the parameters to a function and now this script should run in such a way where a function can be called in parallel with different parameters. Please find below my script, it is actually loading tables:
Code:
full()
{
echo "You entered full $1,$2,$3"
db2 "call util.DATA_REFRESH('LOAD','$1','$2','$3','$2','R','?',?)"  
rc=$?
if [ "$rc" -ne 0 ] ;then
echo "$1.$2" >>failure_list.txt
else 
echo "$1.$2" >>Success_list.txt
fi
}
schema=schema
table=table
nickname=nickname
 
split -l 4 full_refresh.txt
rc=$?
if [ "$rc" -ne 0 ] ;then
mutt -s "Unable to split" $mail_list
exit; 
fi
ls xa*  > list.txt
rc=$?
if [ "$rc" -ne 0 ] ;then
mutt -s "Unable to gather splitted file names" $mail_list 
exit;
fi
 
while read list
do
read_line=0
 
while read line1
do
read_line=`expr $read_line + 1`
echo $line1
eval "$schema""$read_line"=`echo $line1|awk 'BEGIN { FS = "|" } ; {print $1}'`
eval "$table""$read_line"=`echo $line1|awk 'BEGIN { FS = "|" } ; {print $2}'`
eval "$nickname""$read_line"=`echo $line1|awk 'BEGIN { FS = "|" } ; {print $3}'`
export "$schema""$read_line"
export "$table""$read_line"
export "$nickname""$read_line"
 
done < list
 
full $schema1 $table1 $nickname1 & full $schema2 $table2 $nickname2 & full $schema3 $table3 $nickname3 & full $schema4 $table4 $nickname4


Please check where am i going wrong.
full_refresh.txt: input file
here i tried using split command to read 4 lines at once.


Thanks a lot in advance

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.
