in reply to How to get substring between first and second character

You can use split, which uses a regular expression to specify the separator. Only retrieve the second field:
for my $string ("Database_Test_Access_DB", "Database_Development_Access_DB", ) { print((split /_/, $string)[1], "\n"); }

[Lady_Aleena]: Why does grep(/.*$in.*/, @my_modules) work but grep { $_ =~ /.*$in.*/; $_ } @my_modules not work? What did I do wrong in the second?
[tobyink]: Why are you returning $_ n your grep block? You should return a boolean.
[tobyink]: *in your grep block
[tobyink]: You can use grep { $_ =~ /.*$in.*/; } @my_modules but why not stick to grep(/.*$in.*/, @my_modules)? (The latter is faster.)
[shmem]: Lady_Aleena, in the first example grep evaluates the result from grep and if true, returns $_. In the second, it always returns $_
[shmem]: ..the result from the pattern match
[Lady_Aleena]: tobyink, I did after I failed to get the BLOCK to work. I can't seem to get my brain around grep BLOCK, though I'm okay with grep EXPR.
