The right host Come on let displays specify objects to the console money use money.
Come on let's say you're down to your right.
Host come on land.
Since the objects passed along a pipeline and are displayed by default by default for matter but on
other occasions for instance in the first example in the Presidium read.
Host listen if you want to see the welfare of a variable you can use the right host command led to displayed
but its not necessary to write write host variable name will display the same information.
If you type just a variable name the right host command led becomes more useful when you want to customize
the display in some way.
For example you can specify the background color or the foreground color or the well your to be displayed.
In addition to the common parameters the right host command block supports the following parameters
object.
Its a positional parameter in position one specifies the object or objects that are to be written to
the console.
No new line.
A boolean parameter if present after 11 is written to the console.
It's not followed by a newline separator.
A screen to be output to the console when multiple objects are processed by the right host Come on let
the well you're of the stream and is used as the separator between the well used to be displayed background
color.
This perimeter specifies the background color and foreground color parameter.
It specifies the foreground color.
You use the command line out right.
Host.
If you want to output information that is being processed on a pipeline in such scenarios no output
is displayed by default.
For example the following code.
Right host.
Test.
Don't be a swan.
That too.
Well yes the read in from the command line would simply exist as the variables name and pass for and
not be displayed since the to write statements are command to tout in some sentence that may be what
you want.
However if objects are being passed along the pipeline suggesting they get process statement that objects
are passed to the default for matter and then displayed.
Let's run the code with the following command.
It seems that the script file is in the current directory and we can see the result.
We can see that there is no output for the variable name and parse for it on the screen.
If you want to display the wellness of name and the password you can just anchorman's the lines with
the right host command left.
If you want the reli of phosphor to rebuild to be visible in clear text just use the technique which
I've shown in the Brisard in less than on the read host command left.
Now as I think the most useful of right host is left foreground color and background color parameters
which allow you to alter the color on the text or the background when written to the host using the
right host command let the perimeter support the named Koehler's which are enumerated in the following
table.
When you saw the right host command letters to highlight Romes to the user.
For example instead of.
You can read hosta alone to read in data from the user you can use the right host command glad to display
a more visible broomed to the user then use the read host command letter and capturing the user input
in a variable.
Let's take a look at that for an example that shows you how.
Notice that there are no new line parameters used to keep the cursor at the end of the line where the
text was fired.
Well are the right host C'mon left is displayed.
Just to let the foreground color and background color parameters are used to highlight the prompt to
the user.
You can of course abbreviate the name so the foreground color around background color or lower parameters
is just type in F Oh and B.A instead of four.
Ground color and background color so you may want to use the right host Come on left to display Vorderman
and information messages in particular color combinations.
The following code.
Right.
Host color test.
The best one displays ever wardman in red text on white and information in black text also on white.
Output shows the results after entering a password to six characters or shorter them and in a box for
the required 8 characters.
The wearable Lohmann office set initially falls and while loop tests whether or not the lens property
or the password wearable is at least eight characters.
If it is then the value of long enough is set to true if not have worn and is displayed in red text
on a white background and the user was prompted to re-enter the user name and password.
Once the past for two of the specified lands has been entered there while loop exist and an information
message specified in the following code is displayed in black text on white.
