软件包摘要
Storage conversion and expression calculator
历史
项目历史与用法
bcal is a small C command-line calculator aimed at people who think in bytes, sectors, addresses, and binary prefixes.
项目历史
The upstream GitHub repository was created in 2016. Its README describes bcal, the Byte CALculator, as a REPL and single-shot CLI for storage expressions, SI/IEC conversion, byte address calculation, base conversion, and CHS/LBA calculations.
The project keeps dependencies modest: standard libc plus GNU Readline or BSD Editline, with a no-readline build option that uses its own prompt and history-file support.
采用历史
bcal is packaged beyond Homebrew, including Debian, Fedora, Nix, Ubuntu, and openSUSE-family package sets in the supplied package-manager facts. Its README points users to package-manager installation first and shows Repology packaging status.
使用方式
Users run bcal as an interactive storage calculator, pass quoted expressions for one-shot evaluation, convert between decimal, hexadecimal, binary, SI, and IEC units, or calculate disk CHS/LBA values.
When built without Readline, its history file is stored under $XDG_CONFIG_HOME/bcal/history or $HOME/.config/bcal/history.
为什么软件包爱好者会关心
bcal is the kind of niche CLI package that saves repeated mental arithmetic for storage engineers, filesystem debuggers, firmware people, and anyone reading sector offsets in hex.
Its significance is not ecosystem scale but fit: it packages a cluster of byte-addressing calculations that general calculators rarely make pleasant.

Related projects
- bc and dc cover general arbitrary-precision calculation but not bcal's storage-unit and disk-addressing workflow.
- disk utilities, hex calculators, and filesystem debugging tools overlap with bcal's audience.
