This tutorial will show you how to remove all white space characters from a text file. The process is quick and easy, making it the ideal solution for bulk data cleaning.

The “sed remove spaces between words” is a command-line tool that allows users to remove all white space characters from a text file. The sed command can be used with many options, such as the -i option which will replace every instance of a given string in the input file.

How to Remove All White Space Characters From a Text File

Working with the Linux operating system provides you a unique viewpoint on how changing the computer world can be. Getting rid of white space characters in text files, for example, may seem to be a time-consuming operation unless you use Linux as your main operating system.

White spaces do not have to be horizontal, like the spacing between words in this article or other printed characters. White spaces may also be used to separate lines and/or paragraphs vertically. So, what’s the big deal about removing white spaces? The main purpose is to clean up the appearance of your chosen text file.

Text File for Reference

Consider the following text file as an example.

$ sudo nano sample_file.txt File with White SpacesFile with White Spaces

The text file clearly demonstrates symptoms of both vertical and horizontal white space characters, as seen in the above screen shot. To open this file in a numbered view, we may use the cat program with the -n option.

$ cat -n sample_file.txt View File with NumbersView File with Numbers

Spaces, tabs, and line breaks are the most visible white space characters in a text file. We’ll investigate using three built-in Linux commands to delete all of these white space characters.

The first method is to use the tr command.

The tr command will take the above text file as input, translate the contents, eliminate the white space characters, and then write a non-white-space character output back to the file.

We must, however, offer the tr command with precise execution conditions, such as whether to delete horizontal, vertical, or both white space characters.

In the file, delete the horizontal white space characters.

We’ll include the “[:blank:]” character option in a command and then use the cat command to output the file’s final layout.

$ tr -d “[:blank:]” < sample_file.txt | cat -n In the file, delete the horizontal white space characters.In the file, delete the horizontal white space characters.

We have successfully removed the horizontal white space characters from the text file in Linux, as seen in the above result.

To delete both horizontal and vertical white space characters from a text file, use the “[:space:]” option.

$ tr -d “[:space:]” < raw_file.txt | cat -n Remove White Space Characters in FileRemove White Space Characters in File

The second method is to use the sed command.

We may use the sed command in the following way since it is often used with regular expressions:

$ sed ‘s/[[:blank:]]//g’ sample_file.txt | cat -n [Remove Horizontal Spaces] $ sed ‘:a; N; s/[[:space:]]//g; ta’ sample_file.txt | cat -n [Remove All Spaces] Remove White Space Characters in Sed CommandRemove White Space Characters in Sed Command

The second method is to use the awk command.

To dynamically alter text processing, this robust text-processing application takes advantage of its C-like script and other built-in functions and variables.

To eliminate horizontal white space characters, we’ll use its gsub function in the following way.

$ awk ‘{gsub(/[[:blank:]]/,””); print}’ sample_file.txt | cat -n Remove White Space Characters in Awk CommandRemove White Space Characters in Awk Command

We’ll make the following change to the aforementioned command to delete all white space characters from a text file:

‘gsub(/[[:space:]]/,””); print’ sample file.txt | cat -n $ awk -v ORS=”” ‘gsub(/[[:space:]]/,””); print’

Getting rid of unnecessary white space characters in your text files in Linux should be a breeze using the three Linux command options outlined above.

The “sed remove all whitespace” command is used to remove all white space characters from a text file. The command takes the input file as an argument and outputs the new file.
