The official GitHub repository was created in 2012. ### 采用历史 cpulimit has remained packaged as a straightforward Unix-style utility for administrators and users who need to tame batch jobs. The input package metadata shows distribution through Homebrew and several Linux package managers. ### 使用方式 cpulimit controls CPU consumption by sending SIGSTOP and SIGCONT POSIX signals. The README notes that child processes and threads of the selected process share the configured CPU percentage, and documents simple make-based builds for Linux, OS X, and FreeBSD. ### 为什么软件包爱好者会关心 The package is significant because it solves a familiar operational problem with a tiny C tool and no service manager dependency: package it once, expose a single executable, and users can apply soft CPU throttling to existing processes. ### 时间线 - 2012: The opsengine/cpulimit repository was created. - Repository era: v0.1 and v0.2 tags exist in the official GitHub repository. - 2024: The official repository was still receiving updates. ### Related projects - cpulimit is related by purpose to Unix process-management tools such as nice and schedulers, but the README distinguishes it by controlling real CPU usage through stop/continue signals rather than priority. ### 来源 - - - - ## 安全说明 narrow executable package without higher-risk signals. - **Geiger 风险:** 绿色 / 低 - narrow executable package without higher-risk signals ## 源数据库详情 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** cpulimit - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## 其他软件包管理器记录 - Debian apt - cpulimit - 3.1-1: normalized package name match | Debian stable package indexes: cpulimit from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | tool for limiting the CPU usage of a process | https://limitcpu.sourceforge.net/ - Nix - cpulimit: normalized package name match | nixpkgs package indexes: pkgs/by-name/cp/cpulimit/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - cpulimit - 3.0-1: normalized package name match | Ubuntu 24.04 LTS package indexes: cpulimit from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | tool for limiting the CPU usage of a process | https://limitcpu.sourceforge.net/ - apk - cpulimit - 0.2-r4: normalized package name match | Alpine Linux edge package indexes: cpulimit from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | CPU usage limiter for Linux | https://github.com/opsengine/cpulimit - dnf - cpulimit - 0.2^20151118gitf4d2682-5.fc45: normalized package name match | Fedora Rawhide package metadata: cpulimit from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/210a2053c8e007daf9ae39c2a21daaed9b2ddd07d63ecffa597050361e73650c-primary.xml.zst | CPU Usage Limiter for Linux | https://github.com/opsengine/cpulimit - zypper - cpulimit - 3.2-1.5: normalized package name match | openSUSE Tumbleweed package metadata: cpulimit from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | Limit the CPU Usage of a Process | https://limitcpu.sourceforge.net ## 相关链接 - [Source-control packages](https://pkg.so/zh-hans/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/zh-hans/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/zh-hans/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Homebrew utility packages](https://pkg.so/zh-hans/brew-utility-packages/) - Matched Homebrew package provider. - [daemon](https://pkg.so/zh-hans/brew/daemon/) - Shares pkgdb curated category or tags: cli, process-management, system. - [killport](https://pkg.so/zh-hans/brew/killport/) - Shares pkgdb curated category or tags: cli, process-management, system. - [lockrun](https://pkg.so/zh-hans/brew/lockrun/) - Shares pkgdb curated category or tags: cli, process-management, system. - [procps](https://pkg.so/zh-hans/brew/procps/) - Shares pkgdb curated category or tags: cli, linux, process-management, system. - [daemonize](https://pkg.so/zh-hans/brew/daemonize/) - Shares pkgdb curated category or tags: cli, process-management, system. - [procs](https://pkg.so/zh-hans/brew/procs/) - Shares pkgdb curated category or tags: cli, process-management, system. - [reattach-to-user-namespace](https://pkg.so/zh-hans/brew/reattach-to-user-namespace/) - Shares pkgdb curated category or tags: cli, process-management, system. - [psgrep](https://pkg.so/zh-hans/brew/psgrep/) - Shares pkgdb curated category or tags: cli, process-management, system. - [supervisor](https://pkg.so/zh-hans/npm/supervisor/) - Local package facts share a topical domain.
