软件包摘要
Lightweight Expect-like PTY tool for shell scripts
历史
项目历史与用法
`empty` is a lightweight Unix PTY automation tool meant to let shell scripts drive interactive programs without pulling in Tcl/Expect, Perl, Python, or a larger scripting runtime.
项目历史
The official site says `empty` was written by Mikhail E. 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.
采用历史
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.
使用方式
`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.
为什么软件包爱好者会关心
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.
