# 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.
