Introduction – A file is nothing but a container in a Linux based system for storing information. For example, music stored in a file named foo.mp4. Similarly, my cat’s picture stored in kitten.jpg and so on. This page shows various methods to create a file in Linux using the terminal window.
How to create a file in Linux from terminal window?
- Create an empty text file named foo.txt:
touch foo.bar
OR
> foo.bar - Make a text file on Linux:
cat > filename.txt - Add data and press CTRL+D to save the filename.txt when using cat on Linux
- Run shell command:
echo 'This is a test' > data.txt - Append text to existing file in Linux:
echo 'yet another line' >> data.txt
Let us see some examples for creating a text files on Linux operating systems.
How to create a text file using the cat command
To create a text file named sales.txt, type the following command and then press [Enter] key:
cat > sales.txt
Now type your lines of text. For example:
Month, Profit 01/Apr/2004, $1500 01/May/2004, $1600 01/Jun/2004, $1450 01/Jul/2004, $1950 01/Aug/2004, $3950 01/Sep/2004, $2950 01/Oct/2004, $1750 01/Nov/2004, $1950 01/Dec/2004, $3250
When done and you need to save and exit, press Ctrl+D to return to the bash shell prompt. To view file use cat or more command/less command:

Creating a file in Linux using the echo or printf
Let us create a file called quote1.txt using echo command, enter:
echo "While I thought that I was learning how to live, I have been learning how to die." > quote1.txt
OR use the printf command
printf 'Study nature, love nature, stay close to nature. It will never fail you.\n' > quote2.txt
Appending data
Use the the >> instead of > to append data to existing file and to avoid overwriting files. The syntax is:
echo "There is no path to happiness. Happiness is the path." >> quote1.txt printf 'It is ridiculous to think that somebody else can make you happy or unhappy.\n' >> quote2.txt printf 'Happiness does not depend on what you have or who you are. -- Buddha\n' >> quote2.txt

How to do this (creating non-empty file) from executable .sh file? Since we don’t have the option to press Ctrl+D while running executable .sh file.
In your script you put something as follows:
#!/bin/sh file="/tmp/bar.txt" echo "Creating non-empty file called /tmp/foo.txt ..." echo "This is a test" > /tmp/foo.txt echo "Creating another file called ${file} ..." echo "Thursday" > "${file}" ## append ## echo "Friday" >> "${file}"Use the cat command to view those two files.
cat /tmp/foot.txt /tmp/bar.txt@Vivek-
