HOW TO REMOVE EMPTY LINES IN BASH ON LINUX LIKE A PRO



THEO LUCIA



Any Linux users know the potential annoyance that blank lines might pose in a
processable file. In addition to impeding the processing of such files, these
empty/blank lines make it challenging for running software to read and write the
file. This post will look at a few quick methods to remove empty/blank lines in
Bash on Linux.

To simplify the subject, we will talk about 6 possible approaches and look at
some pertinent cases with the required justifications. We will use different
commands and examples to delete the empty line from the file and display the
file.

IN THIS ARTICLE

01 6 Methods to Remove Empty Lines in Bash in Linux
02 How To Recover Accidentally Deleted Files in Linux


6 METHODS TO REMOVE EMPTY LINES IN BASH IN LINUX

The 6 techniques listed below will be used to remove blank lines in Bash in
Linux. Before we begin, let’s see what their functions are:

 * sed command:Stream editor for filtering and manipulating text.
 * grep command: Display lines that match patterns.
 * awk command: The awk utility executes programs written in the awk programming
   language, tailored for manipulating textual data.
 * cat command: Joins files together and prints them on the standard output.
 * tr command: Translate or remove characters.
 * perl command: A programming language that was created specifically for text
   editing.


METHOD 1: RUN THE SED COMMAND TO REMOVE EMPTY LINES IN BASH

In our first solution, we will use the sed command to remove the empty lines in
Bash from the file. The sed command is used to do simple text changes.

 * The stream editor sed can remove blank lines from files, as seen below.
   sed '/^[[:space:]]*$/d' 1_Test.txt

 * When you run the Bash as mentioned above script, you should see an output
   similar to the one below:
   This is the first line.
   This is the second line.
   This is the third line.
   This is the fourth line.

Wherein:

 * '/[[:space:]]*$/d': Portion of the code is used to find and delete the empty
   line from the file.
 * //: The search string is stored there.
 * ^: Start of the string.
 * $: End of the string.
 * d: Remove the matched string.
 * txt: Source file name.


METHOD 2: REMOVE BLANK LINES IN BASH BY USING THE GREP COMMAND

Grep stands for Global Regular Expression Print. We can easily remove the Bash
lines with the grep command, another built-in tool in Bash. A provided file's
text and strings are searched, and the program outputs every line that meets a
pattern.

 * You can use this technique to delete the empty line from the file by
   following the example below.
   grep -v '^[[:space:]]*$' 1_Test.txt

 * The output from running the Bash mentioned above script will look somewhat
   like this:
   This is the first line.
   This is the second line.
   This is the third line.
   This is the fourth line.

Details are as follows:

 * '[[:space:]]*$': A portion of the code is used to find and delete the empty
   line from the file.
 * .: Replaces any character
 * ^: Start of the string
 * $: String's end.
 * E: To match patterns in extended regular expressions.
 * e: For pattern matching in regular expressions.
 * v: To pick out any lines that don't match the file.
 * txt: Name of the source file


METHOD 3: USE THE AWK COMMAND TO REMOVE EMPTY LINES IN BASH

In this method, we'll make advantage of awk, a built-in keyword in Bash Script.
The general-purpose scripting language awk was created for sophisticated text
data processing. Text manipulation, reporting, and analysis are its main uses.

 * The example below demonstrates removing the empty line from the file using
   this keyword.
   awk '!/^[[:space:]]*$/' 1_Test.txt

 * And here’s the output:
   This is the first line.
   This is the second line.
   This is the third line.
   This is the fourth line.

Wherein:

 * /[[:space:]]*$/: The blank lines in a file are recognized and removed using
   the syntax.
 * //: The search string is stored there.
 * ^: Start of the string
 * $: String's end.
 * .: Replaces any character
 * !: Remove the string that matches.
 * txt: Name of the source file


METHOD 4: RUN THE CAT COMMAND  TO REMOVE BLANK LINES IN BASH

Cat is an abbreviation for concatenate. It is commonly used in Linux to read
data from a file. On Unix-like operating systems, the cat command is one of the
most commonly used commands. It provides three text file-related functions:
display file content, combine multiple files into a single output, and create a
new file.

 * We can easily remove blank lines from a file by combining the commands 'cat'
   and 'tr' as shown below:
   Cat 1_Test.txt | tr -s '\n' > new_file.txt

 * Output:
   This is the first line.
   This is the second line.
   This is the third line.
   This is the fourth line.

The following are the specifics:

 * |: The pipe symbol. It uses the output of the first command as an input to
   another command.
 * s: Replace every sequence of a repeated character in the last specified SET.
 * \n: To insert a new line.
 * txt: Name of the source file.


METHOD 5: REMOVE EMPTY LINES IN BASH BY USING THE TR COMMAND

In Linux and Unix systems, tr is a command-line utility that translates,
deletes, and squeezes characters from standard input and writes the results to
standard output. The tr command can remove repeated characters, convert
uppercase to lowercase, and perform basic character replacing and removing. It
is typically used in conjunction with other commands via piping.

 * Squeeze the repeating newline letters to remove the blank lines:
   tr -s '\n' < file.txt > new_file.txt

In the command above, we used:

 * <: This redirection symbol is used to pass the contents of file.txt to the tr
   command.
 * >: Redirection symbol that writes the output of the command to new_file.txt.


METHOD 6: USE THE PERL COMMAND TO REMOVE BLANK LINES IN BASH

Perl is a shortened version of Practical Extraction and Reporting Language. Perl
is a programming language that was created specifically for text editing. It is
now widely used for various tasks such as Linux system administration, network
programming, web development, etc.

 * The following example shows how to use this keyword to remove an empty line
   from a file.
   perl -ne 'print if /\S/' 1_Test.txt > new_file.txt

 * And here's the result:
   This is the first line.
   This is the second line.
   This is the third line.
   This is the fourth line.

Wherein:

 * .: Can be used to replace any character.
 * ^: Beginning of the string.
 * $: End of the string.
 * E: For pattern matching with extended regular expressions.
 * e: Pattern matching for regular expressions.
 * v: Extracting non-matching lines from a file.
 * txt: Name of the source file.
