# Bash Fast Replace
An implementation in bash.
## Usage
To create the corpus.csv and pairs.csv files. And perform the replacements:
```bash
make install # create corpus and pairs
make run # create file with the replaced values
```
Then to test:
```bash
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.
