in reply to what does "$@" mean?

Just as an extra data point, "$@" is used in shell scripts to pass on all arguments that the shell script itself received. In Perl code, there is usually no good reasono to put double quotes around the $@ variable.

[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.)
