chmod
File access controller
Chmod is a Unix command that changes file permissions—who can read, write, or execute a file.
The name abbreviates "change mode." Permissions are typically set with numeric codes: chmod 755 script.sh makes a file executable.
The command is fundamental to system administration and security on Unix-like operating systems.
