huge-merge.pl [OPTIONS] SOURCEDIR

🌸 INPUT 🌸

💖 Required Arguments: 💖

the input arg SOURCEDIR — input to huge-merge.pl should be a single flat directory containing multiple plain text files generated by huge-sort.pl. 🎀 The result file, merge.* (* is a number, the final result file has the maximum number), is in the source directory. ✨

🌟 Optional Arguments: 🌟

  • --keep — turning ON the --keep option will keep all the intermediate merging files. 🫶

🎀 Other Options: 🎀

  • --help — displays the help information. 🙈
  • --version — displays the version information. ⭐

💀 BUGS 💀

There is a limitation in huge-merge.pl, and it is real: when the size of the corpus is very large (>16G) and some of the terms of the bigrams is very long (>30 chars), the program could run out of memory at the huge-merge.pl step. 😭

This is because huge-merge use two hashes to count the frequencies of the first and second term of the bigrams. These two hashes could use up the memory with the increase of the length of the terms and the increase of the number of the terms. 🍓

If just for normal text, terms are within limited length and numbers, the software won't use up the memory. 💜
