DEPLOY is a specialized shell archive (shar) format traditionally generated by various deployment utilities for Unix-like operating systems. It serves to package source code, binaries, and installation scripts into a single self-extracting text file for software distribution. As a legacy format that executes shell commands immediately upon extraction, users should manually inspect the plain text contents for malicious scripts before running the file in a terminal environment.
