Regeler expression->Re^4: Help for generating multiple file from singl e file and

[sarf13]

Hi Marshall thank you very much for help me out. now it working perfectly.
i have one more issue can you please guide me for writing a reguler expression for substitution.
i have this pattern :- 3023NMANS.20111011.2 as a value of hash where starting no (3023) and last no (.20111011.2) will be change and NMANS wil be constant.i need to write reguler expression for substituting this pattern with nothing.
i really appreciate for your help.

Still not sure what you want. To separate the numbers back out, perhaps:

#!/usr/bin/perl -w
use strict;

my $str ='3023NMANS.20111011.2';

my ($front,$end) = $str =~ /^(\d+)NMANS([.\d]+)/;

print "$front  $end\n";  #3023  .20111011.2

if you are using 3023NMANS.20111011.2 as a hash key, then you want to delete it to remove it and its associated value from the hash.
