You can use `n as many times as you’d like to insert as many new lines in the output as you’d like.
Note: The syntax `n uses a backtick, not a single quote. This is a common mistake to avoid.
By default, the entire string appears on one line.
Notice that “hello” and “everyone” appear on two lines.
Also note that you can use `n as many times as you’d like.
"Mavs `nNets `nHawks `nKings `nLakers"
Since we used `n before each new team name, each team name appeared on a new line.

executes a command with the Windows powershell interpreter (Windows only)
Syntax
Arguments
Single text containing instructions sent to the MS Windows powershell.exe
command interpreter.Column of text: output (and error message) yielded and normally displayed by
Powershell on its screen.Single boolean:
%T
ifcommand
has
been executed without error,%F
otherwise.
Description
powershell()
opens a new session of the MS Windows
powershell.exe command interpreter, sends command
to it, lets it processing command
instructions, receives as text the
output
and possible error message yielded by the processing,
and closes the interpreter session.
The starting current working directory and environment variables of the powershell.exe
session are set as described for host().
If an instruction in command
generates an error, the error message
is caught and returned in output
. Nothing is directly displayed
neither in the Scilab console nor in the consolebox.
The effects of valid instructions processed before the erroneous one remain actual |
Any path included in the |
Examples
mkdir mputlTest of listing rmdir
Handling of environment variables, date:
setenv get-Date -format ""yyyy-MM-dd HH:mm"" get-Date -format ''yyyy-MM-dd HH:mm''
--> setenv TEST ABCD; --> powershell("$env:TEST") ans = ABCD --> // Current date: --> [r,ok] = powershell("get-Date -format ""yyyy-MM-dd HH:mm"""); ok ok = F --> [r,ok] = powershell("get-Date -format ''yyyy-MM-dd HH:mm''") ok = T r = 2018-04-30 07:12
Multiple instructions separated with “;”:
--> powershell("echo $env:USERNAME'' uses powershell in Scilab'' ; Get-Date") ans = !Samuel uses powershell in Scilab ! ! ! !lundi 30 avril 2018 07:21:02 ! ! !

Write-Output and Echo in PowerShell
echo ["message"]
echo "This is a sentence."
The output prints the This is a sentence message.
- Text printing.
- Object printing.
- Formatting the output using the
-Format
cmdlets. - Specifying the output encoding.
- Redirecting the output to a file.
- Parameters that allow users to customize the output.
Example of echo in PowerShell
echo "This is another sentence."
$name = "Sara"
echo $name
The output prints the content of the variable.
Available cmdlets are:
Format-Custom
. Customizes the output with different views.Format-Hex
. Shows data in hexadecimal format.Format-List
. Creates lists of objects’ properties.Format-Wide
. Depicts a single object’s property spanning across the screen.Format-Table
. Presents the data in the form of a table.
echo "Number", "Name", "Age", "Location" | Format-Table
Function CheckIfNumberIsPrime($num) {
if ($num -lt 2) {
echo "$num is not a prime number"
}
else {
$isPrime = $true
for ($i = 2; $i -lt $num; $i++) {
if ($num % $i -eq 0) {
$isPrime = $false
break
}
}
if ($isPrime) {
echo "$num is a prime number"
}
else {
echo "$num is not a prime number"
}
}
}
To test the function, run:
CheckIfNumberIsPrime($num)
Replace ($num)
with a prime number, for example:
CheckIfNumberIsPrime(7)
The output confirms seven is a prime number. Next, try 135:
CheckIfNumberIsPrime(135)
The output verifies 135 is not a prime number.
Example of Write-Output in PowerShell
The Write-Output
cmdlet is a powerful command which prints text, objects, and formatted output to the console.
The basic Write-Output
syntax is:
Write-Output [object]
Write-Output "This is another sentence."
Function PrimeNumber?($num) {
if ($num -lt 2) {
Write-Output "$num is not a prime number"
}
else {
$isPrime = $true
for ($i = 2; $i -lt $num; $i++) {
if ($num % $i -eq 0) {
$isPrime = $false
break
}
}
if ($isPrime) {
Write-Output "$num is a prime number"
}
else {
Write-Output "$num is not a prime number"
}
}
Test the function with the number seven by running:
PrimeNumber?(7)
Next, test with 135:
PrimeNumber?(135)
The outputs confirm seven is a prime number while 135 is not.
Write-Host vs. Echo
Write-Output
, on the other hand, writes data to the PowerShell pipeline. The output is displayed on the screen if there is no subsequent command in the pipeline to receive this data.
A key Write-Host
advantage is the customization capability. Write-Host
supports a broader range of formatting options.
To specify the output’s foreground and background colors, use:
Write-Host "Text" -ForegroundColor [Color] -BackgroundColor [Color]
For instance, print a line This sentence is white with a magenta background:
Write-Host "This sentence is white with a magenta background" -ForegroundColor White -BackgroundColor Magenta
The output is displayed in the requested format.
