in reply to Copying a file to a temporary file

According to the docs of File::Temp, if you use File::Temp::tempfile in scalar context, it only returns the filehandle. You can then use this filehandle as an argument to File::Copy::copy, which accepts both filenames and filehandles. Update: You'll have to find out if the warning in File::Copy's docs about using filehandles apply to your situation.

[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
