in thread File search using Grep

vivek, Actually we were planning to load the info in Config1 as hashes and then use it find the value. But as the file increases in size we were worried about the hash performance, so looked at this as alternate approach. So will the hash be better or this? Thanks

    IMO, if the comparison is not involving too many complexities, better use grep
    But it seems that you are ready to load such a big file into hashes, you can use DBM::Deep But since the data is stored in a file, it will not be as quick as normal hash.
    If you give more information about what/why you are trying to load and what/why you are trying to compare, you will get best possible solutions

    There is no data structure that can beat a hash for look-up's. The Perl hash algorithm isn't theoretically perfect, but it is damn fast. End of story.
