Ранас Мукминов – Physical AI: От нейросетей к гуманоидным роботам (страница 10)

COMMENTS In a non-interactive shell, or an interactive shell in which the interactive_comments option to the shopt builtin is enabled (see SHELL BUILTIN COM‐ MANDS below), a word beginning with # causes that word and all remaining characters on that line to be ignored. An interactive shell without the in‐ teractive_comments option enabled does not allow comments. The interactive_comments option is on by default in interactive shells.

QUOTING Quoting is used to remove the special meaning of certain characters or words to the shell. Quoting can be used to disable special treatment for spe‐ cial characters, to prevent reserved words from being recognized as such, and to prevent parameter expansion.

Each of the metacharacters listed above under DEFINITIONS has special meaning to the shell and must be quoted if it is to represent itself.

When the command history expansion facilities are being used (see HISTORY EXPANSION below), the history expansion character, usually !, must be quoted to prevent history expansion.
