Linux mkdir create file

How to create a file in Linux from terminal window? [closed]

• touch /path/to/file for an empty file
• somecommand > /path/to/file for a file containing the output of some command.

 eg: grep --help > randomtext.txt echo "This is some text" > randomtext.txt 

UNIX is not a command line environment, but a family of (very different) OSes. That said: Yes, this should work on most Unices

touch will work in UNIX, because it’s a standard tool. The somecommand example will work because it uses standard syntax. The nano sample may not work because an editor named nano may not be installed (nano is not standardized). The standard editor is ed and could be used in place of nano , or you could use $EDITOR to use your user- or system-configured default text editor, if there is one.

Additionally, you could simply say >/path/to/file to create an empty file, even if you don’t have touch .

Create the file using cat

Now, just type whatever you want in the file:

When I tried cat /etc/systemd/system/sample.service , it said «no such file or directory» rather than creating a new sample.service file.

@TylerH cat /etc/systemd/system/sample.service prints the file to the console cat > /etc/systemd/system/sample.service redirects standard input to the file (which is why you need to close standard input by pressing control-d.

There are several possible solutions:

Create an empty file

touch file >file echo -n > file printf '' > file 

The echo version will work only if your version of echo supports the -n switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.

Create a file containing a newline and nothing else

echo '' > file printf '\n' > file 

This is a valid «text file» because it ends in a newline.

Write text into a file

"$EDITOR" file echo 'text' > file cat > file file 

These are equivalent. The $EDITOR command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat version presumes a literal newline after the \ and after each other line. Other than that these will all work in a POSIX shell.

Of course there are many other methods of writing and creating files, too.

What does P mean in Linux?

Linux Directories mkdir -p

It will create parent directory first, if it doesn’t exist. But if it already exists, then it will not print an error message and will move further to create sub-directories. This command is most helpful in the case when you don’t know whether a directory alredy exists or not.

Can Touch create a directory?

touch is not able to create directories, you need mkdir for that. However, mkdir has the useful -p / —parents option which creates a full directory structure. If you think you will need this more often and don’t want to type the path twice every time, you can also make a Bash function or a script for it.

What Linux command is used to list all files present in a directory?

The ls command is used to list files or directories in Linux and other Unix-based operating systems. Just like you navigate in your File explorer or Finder with a GUI, the ls command allows you to list all files or directories in the current directory by default, and further interact with them via the command line.

How to Create a File in Linux Using Terminal/Command Line

Creating a new file in Linux is straightforward, but there are also some surprising and clever techniques.

In this tutorial learn how to to create a file from a Linux terminal.

• Access to a command line/terminal window (Ctrl–Alt–F2 or Ctrl–Alt–T)
• A user account with sudo privileges (optional for some files/directories)

Creating New Linux Files from Command Line

Linux is designed to create any file you specify, even if it doesn’t already exist. One smart feature is that you can create a file directly, without needing to open an application first.

Here are a few commands for creating a file directly from the command line.

Create a File with Touch Command

The easiest way to create a new file in Linux is by using the touch command.

In a terminal window, enter the following:

This creates a new empty file named test.txt. You can see it by entering:

The ls command lists the contents of the current directory. Since no other directory was specified, the touch command created the file in the current directory.

If there’s already a file with the name you chose, the touch command will update the timestamp.

Create a New File With the Redirect Operator

A redirection operator is a name for a character that changes the destination where the results are displayed.

Right angle bracket >

This symbol tells the system to output results into whatever you specify next. The target is usually a filename. You can use this symbol by itself to create a new file:

This creates a new empty file.
Use the ls command to list the contents of the current directory and find the file test2.txt.

Create File with cat Command

The cat command is short for concatenate. It can be used to output the contents of several files, one file, or even part of a file. If the file doesn’t exist, the Linux cat command will create it.

To create an empty file using cat , enter the following:

Note the redirection operator. Typically, the command displays the contents of test2.txt on the screen. The redirection operator > tells the system to place it in the test2.txt file.

Verify that the file was created:

The system should now have test.txt, test2.txt, and test3.txt in the list.

Create File with echo Command

The echo command will duplicate whatever you specify in the command, and put the copy into a file.

echo 'Random sample text' > test4.txt

Verify that the file was created:

You should see the test4.txt file added to the list. Use the cat command to display the contents of the new file:

The system should display Random sample text (or whatever you entered with the echo command.)

Create File with printf Command

The printf command works like the echo command, and it adds some formatting functionality. To add a single line of text, enter:

printf 'First line of text\n' test5.txt

To add two lines of text, separate each line with the \n option:

printf 'First line of text\n Second line of text' test6.txt

You can use the cat command on either of these files to display their contents.

Note: To use several terminal instances in a single window manager, consider using Linux screen. It enables additional features and an enhanced command line for working with Linux files.

Using Text Editors to Create a Linux File

All Linux distributions have at least one text editor. Some have multiple editors. Each editor has different strengths and features. This will show you three of the most popular.

Vi Text Editor

Vi is the oldest text editor in Linux. It was created alongside the Linux operating system for directly editing text files. Since it’s unlikely you’ll see a Linux distribution without it, it’s a safe editor to know.

To create a file using Vi, enter the following:

Your screen will change. Now you’re in the text editor. Press the letter i to switch to insert mode, then type a few words to try it out.

To save and exit press Esc 😡 and hit Enter .

Vim Text Editor

You may have noticed that the Vi editor wasn’t very user-friendly. Vim is a newer version, which stands for Vi editor, Modified.

Use vim to create a new text file:

This screen will look similar to the Vi editor screen. Press i to insert text, and type a few words. Save file and exit by entering:

(Escape, colon wq, then Enter.)

Nano Text Editor

Nano is a newer and much easier text editor to navigate.

Create a new file by entering the command:

By default, Nano puts you directly into editing mode. It also displays a helpful list of commands at the bottom of the screen.

Enter some text, then press Ctrl+O to save the changes.

Press Ctrl+X to exit the editor.

Note: Learn all you need about Nano in the Install and Use Nano in Linux article.

Now you have several options to create new files in Linux from the command line. Next, learn how to copy files and directories in Linux to manage your files more efficiently.
