Which GREP symbol signifies the end of a line?

The symbol that signifies the end of a line in GREP commands is represented by the dollar sign ($). When using GREP to search through text, the dollar sign indicates that the preceding pattern must occur at the very end of a line. This allows users to effectively pinpoint lines in a text file that conclude with a specific string or character sequence.

For example, if you run a GREP command with a pattern followed by the dollar sign, it will only return lines that end with that pattern, making it a useful tool for parsing logs, configuration files, or any structured text where line-ending conditions are significant.

Other options serve different purposes in GREP syntax. For instance, the caret symbol (^) is used to denote the beginning of a line, whereas the asterisk (*) is a wildcard that matches zero or more occurrences of the preceding character. The symbol @ is not a standard GREP operator. Understanding these distinctions helps users effectively leverage GREP for text searching and manipulation tasks within Linux environments.
