Octave also includes several built-in variables that contain information about the command line, including the number of arguments and all of the options.
Return the command line arguments passed to Octave. For example, if you invoked Octave using the command
octave --no-line-editing --silent
argv
would return a cell array of strings with the elements--no-line-editing
and--silent
.If you write an executable Octave script,
argv
will return the list of arguments passed to the script. See Executable Octave Programs, for an example of how to create an executable Octave script.
Return the last component of of the value returned by
program_invocation_name
.See also: program_invocation_name.
Return the name that was typed at the shell prompt to run Octave.
If executing a script from the command line (e.g.,
octave foo.m
) or using an executable Octave script, the program name is set to the name of the script. See Executable Octave Programs, for an example of how to create an executable Octave script.See also: program_name.
Here is an example of using these functions to reproduce Octave's command line.
printf ("%s", program_name ()); arg_list = argv (); for i = 1:nargin printf (" %s", arg_list{i}); endfor printf ("\n");
See Index Expressions, for an explanation of how to properly index
arrays of strings and substrings in Octave, and See Defining Functions,
for information about the variable nargin
.
