    This is not even valid Perl code, as it does not compile.

    Please take care to test your code and to reduce it to the actual problem. Maybe you want to review system? It shows how to use that function. Also, you may want to learn about quoting, and the difference between strings (what system takes as arguments) and bare, unquoted words in Perl (what perl takes as commands in a program.

      corion as i could nt copy my exact code so i made some typo errors , and this code runs successfully with file names with out white spaces , but i want to make it possible to run with file names having spaces in the arguments also , my problem here is to run with filenames having spaces and i need to use these arguments for other system calls also , in which it is giving problem

      #!/usr/bin/perl use strict; use warnings; my $re; my $qu; $re = $ARGV[0]; $qu = $ARGV[1]; print $re,"\t",$qu,"\n"; $match = system qq(mer -maxmatch "$re" "$re"); $camp = system qq(mer -cods "$re" "$qu"); system qq(perl ma.pl "$re" "$qe");
