in reply to subtract one array from another
This is a FAQ. Please research using perldoc -q and use super search before asking a question...
When you do read the FAQ's you will find a number of variants of the above along with suggestions about how to do this with various constraints.my %hash; $hash{$_}=1 foreach @array_1; @array_2=grep($hash{$_},@array_2);
Also, perl is not restricted to C's overworked and confusing for() syntax. Your for loops above would be much simpler (and would involve less typing, and be less susceptable to fence pst errors) if done as follows
HTH#for (my $search =0; $search<scalar @array1; $search++) # blech, this +isnt C you know for my $search (0.. $#array1) # ahhh thats m +uch better
Sorry to repeat other peoples responses, I failed to press "submit" and then went on to other things.... :-)
