PowerShell Comments

When you want to help others by providing the information about a code, then you must use the comments in that code.

Just like other programming or scripting languages, you can give the comments in a PowerShell for the documentation purpose.

In PowerShell, there are two types of comments:

  • Single-line Comment
  • Multiple-line comment or comment block

Single line comment

Single line comments are those comments in which you can type a hash symbol # at the beginning of each line. Everything to the right of the hash symbol will be ignored. If you write the multiple lines in a script, you had to use the hash # symbol at the starting of each line.
