Zakharov, based on the idea of Daniel J. Bernstein's pty-4.0 but without porting pty-4.0 code. Its copyright notice spans 2005 to 2020. ### Adoptionsgeschichte The project page lists successful compilation and testing on a broad set of Unix-like systems, including BSDs, macOS, Linux, Solaris, AIX, HP-UX, OSF1, and Cygwin. That portability is the main adoption story rather than a large ecosystem. ### Wie es verwendet wird `empty` runs a process under a pseudo-terminal and then sends or waits for text through named input and output files. The homepage compares a short telnet login sequence against Tcl/Expect, Perl Expect, and Python Pexpect examples. ### Warum Paket-Nerds sich dafür interessieren The package is interesting because it keeps the old Unix promise small: PTY scripting from plain shell, entirely in C, with minimal dependencies. It is the sort of utility that survives in package managers because it solves one awkward automation job without dragging in a language stack. ### Related projects - The homepage compares `empty` directly with Tcl/Expect, Perl Expect, and Python Pexpect, and notes the conceptual link to pty-4.0. ### Quellen - - ## Sicherheitshinweise generalized runtime or code generation signal. - **Geiger-Risiko:** yellow / mittel - generalized runtime or code generation signal ## Details aus der Quelldatenbank - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** empty - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Andere Paketmanager-Einträge - Nix - empty: normalized package name match | nixpkgs package indexes: pkgs/by-name/em/empty/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Verwandte Links - [Secret-risk packages](https://pkg.so/de/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://pkg.so/de/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://pkg.so/de/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://pkg.so/de/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [sexpect](https://pkg.so/de/brew/sexpect/) - Shares pkgdb curated category or tags: automation, cli, developer-tools, expect, pty. - [expect](https://pkg.so/de/brew/expect/) - Shares pkgdb curated category or tags: automation, cli, developer-tools. - [entr](https://pkg.so/de/brew/entr/) - Shares pkgdb curated category or tags: automation, cli, developer-tools. - [retry](https://pkg.so/de/brew/retry/) - Shares pkgdb curated category or tags: automation, cli, developer-tools. - [appium](https://pkg.so/de/brew/appium/) - Shares pkgdb curated category or tags: automation, cli, developer-tools. - [apify-cli](https://pkg.so/de/brew/apify-cli/) - Shares pkgdb curated category or tags: automation, cli, developer-tools. - [robot-framework](https://pkg.so/de/brew/robot-framework/) - Shares pkgdb curated category or tags: automation, cli, developer-tools. - [docker-gen](https://pkg.so/de/brew/docker-gen/) - Shares pkgdb curated category or tags: automation, cli, developer-tools. - [dialog](https://pkg.so/de/brew/dialog/) - Local package facts share a topical domain.
