dos
Execute DOS command and return output
For platform-independent code, use the system
command.
Description
Examples
Display Operating System Command Status and Output
Display the current folder using the cd
command. A
status
of zero indicates that the command
completed successfully. MATLAB® returns a character vector containing the current folder
in cmdout
.
command = 'cd';
[status,cmdout] = dos(command)
Input Arguments
command
— Operating system command
string | character vector
Operating system command, specified as a string or a character vector. The command can be a Windows® UI program that opens a user interface, or a DOS console command that you typically run in a DOS command window. The command executes in a DOS shell, which might not be the shell from which you started MATLAB.
Example: 'dir'
Output Arguments
status
— Command exit status
0 | nonzero integer
Command exit status, returned as either 0
or
a nonzero integer. When the command is successful, status
is 0
.
Otherwise, status
is a nonzero integer.
If
command
includes the ampersand character (&
), thenstatus
is the exit status whencommand
startsIf
command
does not include the ampersand character (&
), thenstatus
is the exit status uponcommand
completion.
cmdout
— Output of operating system command
character vector
Output of the operating system command, returned as a character vector. The system shell might not properly represent non-Unicode® characters.
Extended Capabilities
C/C++ Code Generation
Generate C and C++ code using MATLAB® Coder™. (since R2024b)
Usage notes and limitations:
The
-echo
flag must be compile constant.stdin
of the calling process is inherited on Windows and UNIX®.On UNIX, if a second output is requested,
stdout
is redirected to a pipe. Otherwise,stdout
is inherited from the calling process.On Windows, the
nargout
determines whether the output read from the pipe is stored in a variable or sent tostdout
of the calling process. If the number of arguments is 1, the output from the pipe is sent tostdout
. Otherwise, it is stored in a variable.
