Which symbol is used for comments in Shell Scripts?

In shell scripts, the symbol used for comments is the hash mark, or pound sign, represented as '#'. When a line starts with this character, the interpreter ignores everything that follows it on that line, treating it as a comment rather than executable code. This is particularly useful for adding notes and explanations in scripts to enhance readability for anyone reviewing the code later.

Using comments effectively can clarify the purpose of various code sections, helping both the original author and future users understand what the script is intended to do and how it operates.

The other symbols mentioned have different meanings in various contexts. For example, the double forward slash '//' is often used for comments in programming languages like Java or C++, but not in shell scripts. The /* and */ symbols are used for multi-line comments in languages like C and Java, rather than in shell scripting. The double dash '--' is utilized in some command-line interfaces as a marker for the end of command options but does not serve as a comment in shell scripts.
