What Is Bash Syntax Error  #

It is an error when you don’t follow the syntax in the right direction in “.sh” files using git add. And if you are missing some quotation marks you will get the error syntax error near the unexpected token `newline’. These quotation marks let the syntax understand an entity with a proper character, writing the Bash syntax script you have to be careful about quotations and angle brackets. The other way result will show you the error.  

The Reason It Happens  #

This error message comes when some special characters, quotation marks, and writing a Bash script are missing. The Bash syntax error denotes that there is something wrong with the coding or that a bad script is written somewhere in the command. Commonly escaping missing space, characters, or comas.

During the execution process, it is not that easy to find out the syntax error that is syntax error near unexpected token `newline’. It may require you to change your coding many times for resetting the script. You need to take care of writing the code in Bash as it might be difficult to find out the errors easily.

The Solution Methods  #

The Bash syntax error may occur in multiple scenarios and it becomes difficult to find out the exact error until you review all of the scripts again. Though it is time taking, there is nothing to be worried about that because in the solution section it will be identified and rectified. It will be observed that the error encounters during the execution process of a single Bash shell command. And why it gives an unsuccessful result as an unexpected token error. While fixing the single command error the way you can use it to add or remove an incorrect character that can cause the syntax error in the command. You can fix the error when you run a command having a syntax error. Take care of the mentioned error line by the Bash syntax. You can execute the error in the Bash shell to get fast access without rerunning and changing the script again and again. You need to update the command in the way correct to find that the script works properly. For instance, if you have a file on a Linux system where you want to rename it to report_jan.csv, you will write the code in this way;

mv report(july).csv report_jan.csv

if you run this script you will get the error message, but what is the reason that it gives you an error because the parenthesis () are used to create subshell in Bash, simply they are considered as special characters, and special characters need quotes. 

-bash: syntax error near unexpected token `('

A special character can be escaped if treated as a normal character in command and to escape you need to use the backslash.

mv report(july).csv report_july.csv

No error will be shown now.

-rw-r--r--   1 ec2-user ec2-user   28 Jun 28 22:29 report_july.csv

If you are writing Bash syntax script and you are missing between space that is considered as a character and ([), you will find the error message.

The correct way to write the script will be like this:

#!/bin/bash

DAY="Monday"

if [ $DAY == "Monday" ]; then

  echo "Today is Monday"

else

 echo "Today is not Monday"

fi

Writing a Bash script can cause an error at the beginning like this:

localhost)$ for i in {0..10} ; do echo $i ; then echo "Printing next number" ; done

This single line will give you the result as;

-bash: syntax error near unexpected token `then'

If you are using For Loop then the written syntax in Bash should be as under:

for VARIABLE in {0..10}

do

  echo command1

  echo command2

  echo commandN

done

you can see here that the semicolon is used to separate the commands in Bash. Many other reasons are related to the codes that may cause Bash syntax error near unexpected token ‘newline’. Whenever you get this error means you are making a syntax error, first of all, read the file that contains the cat command.

cat file. sh

Note the use of special characters. The < character is used for input redirection, and redirection.

For this, if you are using the angle brackets “<>” must be used in single or double quotes, otherwise you will get the problem. For example, the following code will create an error syntax error near the unexpected token ‘newline’.

#!/bin/bash

str=

Using the quotes will give you the correct results like whether single or double quotes,

#!/bin/bash

str=""

#!/bin/bash

str=''

Another important point is that you can’t use angle brackets in Bash command line parameters without quotation signs. Let’s see the example;

If you have a login and password program containing an angle bracket will deliver the error syntax error near the unexpected token ‘newline’.

./login --username admin --password 1234<</code>

The argument should enclose in single or double quotes;

./login --username admin --password "1234<"</code>

The Conclusion  #

The Bash syntax error near unexpected token ‘newline is an error that is invoked when messing with the Bash script that doesn’t use the syntax properly to execute the git add. The most important problem related to the syntax includes “<>” (angle brackets) it shouldn’t be used in both cases without single or double quotes, so wrapping up the angles brackets in quotes can stop this error. Another problem is the missing characters and spaces that can be avoided before you execute your program.
