 ## Shell script
 
-The `bench.sh` script is available to benchmark the code against other versions or fzf using `tmux` and querying the output. This is by no means a precise or foolproof way of running benchmarks, but it has the added benefit of allowing us to benchmark against `fzf` and of giving us resource metrics.

-You can use it directly using `./bench.sh <binary> -n <number of items> -r <number of runs>`, or generate the data using `./bench.sh -g <output file> -n <number of items>`, then `./bench.sh <binary> -f <file> -r <number of runs>`

 ### Criterion benchmarks
 
 Criterion benchmarks are available to measure skim's performance more precisely.
-To run them, you need to generate input data using `./bench.sh -g benches/fixtures/10M.txt -n 10000000 && ./bench.sh -g benches/fixtures/1M.txt -n 1000000`, then run `cargo bench -j 1`.
+To run them, you need to generate input data using `./bench.py -g benches/fixtures/10M.txt -n 10000000 && ./bench.py -g benches/fixtures/1M.txt -n 1000000`, then run `cargo bench -j 1`.
 
 These will run for several minutes.
