How to add block comment in shell script

The shell script is a set of instructions which are written using a programming language called bash. It is used for running commands, managing files and directories on your computer. Shell scripts often contain many lines of code and sometimes it becomes difficult to find the exact line that needs to be edited or added. In such cases, block comments can help you out by putting a comment in front of each section of code you want to edit so that you can easily find those lines later on without having to scroll through all other lines first.

How do I insert a comment in a bash script?

  • The hash symbol: #
  • The pound symbol: $
  • The double-dash symbol: —
  • The semicolon: ;
  • The single-dash symbol: –

How do I comment in bash shell?

You can use # at the beginning of a line to create a comment. This will tell the shell to ignore everything that follows on that line.

You can also use it at the end of a line, which will comment out everything from there until the end of the file.

Finally, if you want to have some sort of commentary near your code but not in its entirety, use # at the beginning of each relevant section and then ; at the end (or vice versa).

How do you comment in a batch script?

The REM command is used to add comments to batch scripts.

A simple example would be:

REM This is a comment line

The comment line can be any length, but it must start with an equal sign (=), followed by one or more characters, and then end with a carriage return (CR).

How do you comment multiple lines?

As mentioned, the syntax for a shell comment is as follows:

# comment 1

You can also use C-style comments in your shell scripts. To do so, simply enclose the text you want to remain untouched by the script with two forward slashes (//):

// This line will be ignored by the script and all of these will be ignored as well.

There are many options for commenting out multiple lines of code, including using shell scripts themselves. You can use #!/bin/sh at the top of your file and put all your code in there. Then put another #!/bin/sh at the bottom of your file and then you don’t have to worry about compiling anything because it already runs from that first line!


In this article, we will be discussing the various ways in which you can add comments in your shell script. We will also discuss how to format these comments and some of the best practices for adding them into your scripts. If you wants to read blogs on ” Block comments in Java”  click here.

Pros And Cons Of Cryptocurrency

There are several advantages of cryptocurrency. However, there are certain disadvantages of this new form of digital money that you should know about. In this article, I have explained the various pros and cons of cryptocurrency which will help you decide if investing in cryptocurrency is the right thing for you.

Pros and cons of Cryptocurrency

Let’s take bitcoin to illustrate this point. Bitcoin transactions are monitored on blockchain. Once a transaction gets complete and gets recorded in the public ledger, it cannot be altered. These transactions can be verified by anyone and anytime. But, nobody can manipulate it in any way.

2. Protection from identity theft

The transaction of digital currencies is completely under your control. The transactions are independent of the identities of the persons/parties making them. This keeps the transaction safe and protects the user from identity theft.

3. Portability

Physical money is traceable. This is not the case with cryptocurrency. Cryptocurrency is easily transportable without detection. You can easily carry billions of Bitcoin dollars with you in person using a memory drive.


1. Market fluctuations

Cryptocurrencies can be subject to market fluctuations. You need to understand that the market prices keep on changing. Check this website to know about the changes in market prices of cryptocurrencies. You can also check the latest coin listings on exchanges through this website.

This is the reason why there are only a few businesses which accept payment in the form of bitcoin or other cryptocurrencies.

3. Cannot be recovered

One of the biggest disadvantages of cryptocurrency is that once it is lost, it cannot be recovered. Unlike banks, which gets your money back in case of stolen credit card or hacking, lost digital coins cannot be retrieved.

Transactions made through bitcoins or other cryptocurrencies are virtually untraceable. This makes it a good source for criminals to make transactions without the risk of getting traced. This is the reason why cryptocurrency is banned in some countries.

So, having gone through all the pros and cons of cryptocurrency, do you think the pros outweigh the cons? In my opinion, it depends on your purpose of use. If you are thinking about using cryptocurrencies for your daily transactions, it is not worth it. However, if your intention is to stay invested, cryptocurrency is a great option.
