You can do that using the conv command line option (with ucase as its value). Here's an example: The above screenshot shows the command as well as the input text. The key combination Ctrl+d was used to tell dd that we're done entering the input, and as soon as that was done, the command produced the following output. Resetting the Mac from Open Firmware. Restart the Mac and immediately hold down the Command Option+O F keys. This will boot you into open firmware. When it stops, you will be looking at a ' prompt. At the prompt, type each of the next three lines, followed by pressing the Return key.

Dec 31, 2020 Alternatively known as Cmd+A, Command+A is a keyboard shortcut most often used to select all text, files, pictures, or other objects while in a graphical user environment. Tip On Windows computers, the keyboard shortcut to select all is Ctrl + A. To prevent command injection attacks, consider the following practices: Do not allow any user input to commands your application is executing. Only use secure APIs for executing commands, such as execFile. Unlike other APIs, it accepts a command as the first parameter and an array of command line arguments as the second function parameter.
-->You can use
wt.exe
to open a new instance of Windows Terminal from the command line. You can also use the execution alias wt
instead.Note
If you built Windows Terminal from the source code on GitHub, you can open that build using
wtd.exe
or wtd
.Kw Command
Command line syntax
The
wt
command line accepts two types of values: options and commands. Options are a list of flags and other parameters that can control the behavior of the wt
command line as a whole. Commands provide the action, or list of actions separated by semicolons, that should be implemented. If no command is specified, then the command is assumed to be new-tab
by default.To display a help message listing the available command line arguments, enter:
wt -h
, wt --help
, wt -?
, or wt /?
.Options and commands
Below is the full list of supported commands and options for the
wt
command line.Option | Description |
---|---|
--help , -h , -? , /? | Displays the help message. |
--maximized , -M | Launches the terminal maximized. |
--fullscreen , -F | Launches the terminal as full screen. |
--focus , -f | Launches the terminal in the focus mode. Can be combined with maximized . |
--window , -w <window-id> | Launches the terminal in a specific window. |

Note
When opening Windows Terminal from cmd (Command Prompt), if you want to use your custom 'cmd' profile settings, you will need to use the command
wt -p cmd
. Otherwise, to run your default profile settings, just use wt cmd
.Command line argument examples
Commands may vary slightly depending on which command line you're using.
Passing an argument to the default shell
To start an instance of Windows Terminal and have it execute a command, call
wt.exe
followed by your command.![What does command a do on a mac What does command a do on a mac](https://i.stack.imgur.com/deCNL.png)
Here's an example of calling Windows Terminal to pass a ping command argument to echo an IP address:
Here's an example of calling Windows Terminal to open a new tab with a PowerShell command line, confirming to call the Start-Service command, and opening another new tab with Windows Command Prompt open to the
/k
directory:Target a specific window
Below are examples of how to target specific windows using the
--window,-w
option.Execution aliases do not work in WSL distributions. If you want to use wt.exe from a WSL command line, you can spawn it from CMD directly by running
cmd.exe
. The /c
option tells CMD to terminate after running.Open a new profile instance
To open a new terminal instance, in this case the command will open the profile named 'Ubuntu-18.04', enter:
Execution aliases do not work in WSL distributions. If you want to use wt.exe from a WSL command line, you can spawn it from CMD directly by running
cmd.exe
. The /c
option tells CMD to terminate after running.The
-p
flag is used to specify the Windows Terminal profile that should be opened. Substitute 'Ubuntu-18.04' with the name of any terminal profile that you have installed. This will always open a new window. Windows Terminal is not yet capable of opening new tabs or panes in an existing instance.Target a directory
To specify the folder that should be used as the starting directory for the console, in this case the d: directory, enter:

Execution aliases do not work in WSL distributions. If you want to use wt.exe from a WSL command line, you can spawn it from CMD directly by running
cmd.exe
. The /c
option tells CMD to terminate after running.Multiple tabs
To open a new terminal instance with multiple tabs, enter:
PowerShell uses a semicolon ; to delimit statements. To interpret a semicolon ; as a command delimiter for wt command-line arguments, you need to escape semicolon characters using backticks. PowerShell also has the stop parsing operator (--%), which instructs it to stop interpreting anything after it and just pass it on verbatim.

option tells CMD to terminate after running and the ;
backslash + semicolon separates commands.Multiple panes
To open a new terminal instance with one tab containing three panes running a Command Prompt profile, a PowerShell profile, and your default profile running a WSL command line, enter:
PowerShell uses a semicolon ; to delimit statements. To interpret a semicolon ; as a command delimiter for wt command-line arguments, you need to escape semicolon characters using backticks. PowerShell also has the stop parsing operator (--%), which instructs it to stop interpreting anything after it and just pass it on verbatim.

. The /c
option tells CMD to terminate after running and the ;
backslash + semicolon separates commands.The
-H
flag (or --horizontal
) indicates that you would like the panes to be split horizontally. The -V
flag (or --vertical
) indicates that you would like the panes split vertically.Multiple tabs and panes
The
new-tab
and split-pane
commands can be sequenced to get multiple tabs, each with split panes. To open a new terminal instance with two tabs, each with two panes running a Command Prompt and a WSL command line, with each tab in a different directory, enter:PowerShell uses a semicolon ; to delimit statements. To interpret a semicolon ; as a command delimiter for wt command-line arguments, you need to escape semicolon characters using backticks. PowerShell also has the stop parsing operator (--%), which instructs it to stop interpreting anything after it and just pass it on verbatim.
Execution aliases do not work in WSL distributions. If you want to use wt.exe from a WSL command line, you can spawn it from CMD directly by running
cmd.exe
. The /c
option tells CMD to terminate after running and the ;
backslash + semicolon separates commands. Note to specify a Windows directory as the starting directory for wsl.exe
that two backslashes
are required.Tab title
To open a new terminal instance with custom tab titles, use the
--title
argument. To set the title of each tab when opening two tabs, enter:Execution aliases do not work in WSL distributions. If you want to use wt.exe from a WSL command line, you can spawn it from CMD directly by running
cmd.exe
. The /c
option tells CMD to terminate after running and the ;
forward-slash + semicolon separates commands.Using application title
To open a new terminal instance allowing applications within it to set the tab title by sending title change messages, use the
--useApplicationTitle
flag. To suppress these messages, use the --suppressApplicationTitle
flag. If none of these flags are provided, the behavior is inherited from the profile's settings. To open a tab with title tabname
that will not be overridden by the application, enter:Execution aliases do not work in WSL distributions. If you want to use wt.exe from a WSL command line, you can spawn it from CMD directly by running
cmd.exe
. The /c
option tells CMD to terminate after running and the ;
backslash + semicolon separates commands.Tab color
To open a new terminal instance with custom tab colors, use the
--tabColor
argument. This argument overrides the value defined in the profile, but can be overridden as well using the tab color picker. In the following example, a new terminal is created with two tabs of different colors:Execution aliases do not work in WSL distributions. If you want to use wt.exe from a WSL command line, you can spawn it from CMD directly by running
cmd.exe
. The /c
option tells CMD to terminate after running and ;
separates commands.When
--tabColor
is set for a tab, it is associated with the first pane of this tab. Hence in a tab with multiple panes, the color will be applied only if the first pane is in focus. To set the tab color for additional panes, you will need to add the --tabColor
parameter to the split-pane
subcommand as well. In the example below, a tab with two panes is created with tab colors specified for each pane:Color scheme
To open a new terminal instance with a specific color scheme (instead of the
colorScheme
set in the profile), use the --colorScheme
argument. This argument overrides the value defined in the profile.Execution aliases do not work in WSL distributions. If you want to use wt.exe from a WSL command line, you can spawn it from CMD directly by running
cmd.exe
. The /c
option tells CMD to terminate after running and ;
separates commands.Tab focus
To open a new terminal instance with a specific tab in focus, use the
-t
flag (or --target
), along with the tab-index number. To open your default profile in the first tab and the 'Ubuntu-18.04' profile focused in the second tab (-t 1
), enter:Execution aliases do not work in WSL distributions. If you want to use wt.exe from a WSL command line, you can spawn it from CMD directly by running
cmd.exe
. The /c
option tells CMD to terminate after running and the ;
backslash + semicolon separates commands.Examples of multiple commands from PowerShell
Windows Terminal uses the semicolon character
;
as a delimiter for separating commands in the wt
command line. Unfortunately, PowerShell also uses ;
as a command separator. To work around this, you can use the following tricks to run multiple wt
commands from PowerShell. In all the following examples, a new terminal window is created with three panes - one running Command Prompt, one with PowerShell, and the last one running WSL.The following examples use the
Start-Process
command to run wt
. For more information on why the terminal uses Start-Process
, see Using start below.What Does Command A Do
Single quoted parameters
In this example, the
wt
parameters are wrapped in single quotes ('
). This syntax is useful if nothing is being calculated.Escaped quotes
When passing a value contained in a variable to the
wt
command line, use the following syntax:Note the usage of
`
to escape the double-quotes ('
) around 'Windows PowerShell' in the -p
parameter to the split-pane
parameter.Using start
All the above examples explicitly used
start
to launch the terminal.The following examples do not use
start
to run the command line. Instead, there are two other methods of escaping the command line:Windows Cmd
- Only escaping the semicolons so that
PowerShell
will ignore them and pass them straight towt
. - Using
--%
, so PowerShell will treat the rest of the command line as arguments to the application.
What Does Shell Do While Executing A Command
In both of these examples, the newly created Windows Terminal window will create the window by correctly parsing all the provided command-line arguments.
What Is Command Prompt Windows 10
However, these methods are not recommended currently, as PowerShell will wait for the newly-created terminal window to be closed before returning control to PowerShell. By default, PowerShell will always wait for Windows Store applications (like Windows Terminal) to close before returning to the prompt. Note that this is different than the behavior of Command Prompt, which will return to the prompt immediately.
