Bash Scripting 7

 Bash Scripting 

Comments:

• Comments are the normal language text that will be written inside code to give idea about the code if we take a look at it after a period of time.
• If we see a big code which we done previous after a long time.The first question arise in mind is        "Whether I have done it or With what idea i wrote🤔 , May be sometimes what language is this😅".
• But if these line don't match the syntax of a particular language or made someother meaning to code.It will completely mess up the code.
• Every language has there own way of writing comment.
• The only thing is ,the statement we write should not disturb the original code.
• It should be a piece of line ,which should be read only by the human and not by the compiler.
• In bash ,we have two ways of commenting,
• Single line comment
• This will comment only one line.
• The command format should be repeated for everyline we wrote.
• The "#" is used to make single line comment.
• For Example,
•  <# This line is a comment.>
  
  
  
• The red marked are comment.The yellow box is the general code of bash.
• Multi line comment
• This can be used to comment certain number of comment.
• If in a code we had more than one continuous comment line we can use multiline comment instead of repeating single line comment for multiple times.
• The " : ' .....Comments (can be multiline)   '
• For Example:
• <: ' 
• Comment1
• Comment2
• Comment3 '>
