Quick Start

• On Arch

paru -S fastwc 
# or fastwc-bin for a prebuilt release

• Non-arch

cargo install fastwc

Note: Make sure ~/.cargo/bin is in your PATH. It's added automatically by rustup, but if fastwc isn't found, add this to your shell config file:

# If you use Bash:
export PATH="$HOME/.cargo/bin:$PATH"

# If you use Fish:
fish_add_path $HOME/.cargo/bin

# If you use Zsh:
export PATH="$PATH:$HOME/.cargo/bin"

# Use it!
fastwc /path/to/file

Benchmarks

Benchmark 1: 1.5 GiB file

Tool	Time	Speed vs fastwc
fastwc	0.16s	1x (baseline)
wc	23s	141.6x slower

The gains in speed are higher the bigger the file.

Uninstall

cargo uninstall fastwc

Usage

fastwc does not add any additional flags to the original wc. All flags are the same and behave the same. The --help message was changed though.
