oohid is a fast and efficient command-line interface (CLI) tool for generating Universally Unique Identifiers (UUIDs) in various formats. It allows users to output UUIDs directly to a file or standard output (stdout). Features options for custom formatting, duplicate checking, and verbose output.
- Generate multiple UUIDs in a single command.
- Custom formatting options for UUIDs.
- Output to a file or stdout.
- Check for and remove duplicate UUIDs.
- Verbose mode for additional output information.
- Pretty fast, I'm sure. Uses Rayon for embarassingly parallel tasks, probably some more optimization work to do. SIMD or assembly-level stuff or cache optimization, IDK. ~1 mil/s on my MacBook Pro w. M2 Pro.
- Formatting options suitable for Python/Rust.
- For the extra-paranoid (even with 1m UUIDs, the possibility of duplicates is low), duplicate checking.
To install oohid, ensure you have Rust and Cargo installed on your system. Then run the following command:
cargo install oohid
To generate a single UUID and print it to stdout:
oohid
Generate 5 UUIDs:
oohid --count 5
or
oohid -c 5
Specify a custom format for the UUIDs (ul
for bare with comma, q
for quoted, etc.):
oohid --count 5 --format ul
or
oohid -c 5 -f ul
Direct the output to a file:
oohid --count 10 --output uuids.txt
or
oohid -c 10 -o uuids.txt
Check and remove duplicate UUIDs:
oohid -c 100 --check
Display benchmarking and checking results:
oohid -c 100000000 -f qlbl -o uuids.txt --check --verbose
Customize the behavior of oohid through command-line flags. Refer to the help command for more details:
