Different Ways To Repeat Your Last Command In Linux

Re-run Previously Executed Commands without Typing Them in Linux and Unix

Today, I will be teaching you how to repeat your last command in Linux. You don't have to re-type the previously executed commands in your Shell. Of course, we use the UP arrow key to select the last executed commands and hit ENTER to execute them. However, there are also other a few ways to re-run previous commands.  There could be many ways to repeat the last commands in Unix-like systems, but these are the only ways I am aware of now. All these commands were tested in my Arch Linux and Ubuntu desktop with BASH shell.

A word of caution: When you try the following methods, the previously executed commands will run immediately. Just make sure your last command is not going to perform ANY HARMFUL OPERATIONS like formatting a partition or deleting files, folders or any other important data.

Repeat Last Command in Linux

Let us run a few commands.

$ ls -l
$ pwd
$ date
$ uname -r

As I mentioned earlier, we can execute the last command by simply pressing the UP arrow and hit ENTER key. This is the most commonly used way by many users to execute the previous command. This method will work on all SHELL, regardless of the Linux distribution you use.

However, like I said already, there are a few other methods to do this.

Now, let me show you how to execute the last command with some practical examples.

Method 1 - Repeat Last Command using Exclamation Marks

To execute any last executed command, just type double exclamation marks, and hit ENTER:

$ !!

This will execute the last command. Sample output would be:

uname -r

Add sudo in-front of !! to execute the last command as root user like below.

$ sudo !!

You can also use the following to execute the previous command as sudo user:

$ su -c "!!"

Sample output:

su -c "uname -r"

Cool, isn't it? You don't need to type the last command completely. It could be useful when you’ve already executed a very long command, and don't want to re-type the same command again.

Method 2 - Repeat N-th Command

You might have run so many commands, and want to repeat a specific command. What will you do? Simple! You can do this by typing a specific word of the previous command.

To repeat previous command that starts with a specific word/letter, for example un, just type:

$ !un

The above command will execute last command that starts with the letters "un".

Sample output:

uname -r

As you see in the above example, you don't need to type the whole command (i.e uname -r). Instead, just type a few letters of the command, and any previous command that contains words will run.

Also, If you know the full command name, just type it like below:

$ !uname

It will execute the last command.

What if you don't want to repeat the last command, but just display it. Sometimes, you don't want to run a command, but just retrieve it from the history. If so, find the prefix number of the command you want to run:

$ history | grep -i "source"

Sample output:

1664 source googler_at
1678 source googler_at 
1685 source ~/.bashrc
2037 history | grep -i "source"

Let us say you want to retrieve the 1685th command, but don't want to run it immediately, add :p next to the command like below.

$ !1685:p

This will display 1685th command from the history, but won’t execute it.

Another way to do this is by searching your command line history using CTRL+R. Press CTRL+R key to search through the command line history. I personally prefer this method. It searches history interactively which I think feels safer than executing commands blindly from the BASH history.

Have a look at the following example. In the following example, I searched for "ost", which displayed the last command “sudo netctl restart ostechnixjio” in the history that contained the word "ost". Then, I hit ENTER to execute the command immediately or right arrow key complete the command and hit ENTER key to execute it.

(reverse-i-search)`ost': sudo netctl restart ostechnixjio
Search bash history using reverse search
Search bash history

Just in case, you want to edit/modify the last command before executing it, just press the left arrow key, then edit the last command and hit ENTER to execute it. Some commands may start with same letters. In such cases, keep hitting the CTRL+R key to bring back the command you wanted to run.

Method 4 - Use Hyphen Symbol with Command Prefix Numbers

Here is yet another way to run the previous command.

$ !-1

Sample output:

uname -r

Similarly, !-2 will run the second last command, !-3 will run the third last command, and so on.

Method 5 - Use CTRL+p and CTRL+o to Re-run Last Commands

I don't want to type any command manually. Is there any way to repeat a last command by simply pressing a particular key(s) in my Keyboard? Yes, of course!

Press CTRL+P to switch to the last command, and then press CTRL+O to execute it. This will do the wonder. No configuration needed! You can use CTRL+O as many times as you want to keep re-executing the last commands.

Method 6 - Repeat Previously Executed Commands using fc Command

This is another way to repeat the last executed command. The fc command is used to list, edit and re-run the previously entered command.

To repeat the last command using fc, simply run:

$ fc -s

Sample output:

uname -r

Method 7 - Repeat Last Commands with Last Used Arguments

You can re-run the last command with last used argument by simply adding "!$" letters. This will not only add the last used arguments in the command but also re-run the whole command as well.


$ uname -r

Now type uname followed by !$ letters to re-run the last command with the last used argument i.e. -r.

$ uname !$
uname -r

Method 8 - Add Last Used Arguments in a Command using ALT+period Key

As one of our reader said in the comment section, we can also use ALT+. keys (press ALT+period) to retrieve the last command without running it. However, there is one limitation. Hitting ALT+. will only retrieve the last used argument in the command.

For example, if your previous command is "uname -r", it will only bring back the -r argument, but not the entire command.


And, that's all. These are a few ways to repeat your last command without typing it in the Terminal. If you want to view the output of your last commands without actually having to retype them, these methods will help.

If you know any other methods, please let me know in the comment section below. I will check and update the guide accordingly.

You knew now how to repeat a previously executed command. How do you repeat a Linux command or program until it succeeds? Well, that's easy! Refer the following guide for more details.

Hope this helps.
