Bash Fast Replace

An implementation in bash.

Usage

To create the corpus.csv and pairs.csv files. And perform the replacements:

make install # create corpus and pairs
make run # create file with the replaced values

Then to test:

make test # Checks that the replacement worked

Conclusions

shuf is amazing. Using /dev/urandom directly produces broken pipe errors on when using Make.

Speed is not great... But no surprize there.
