How to refer a variable inside the argument list of power shell start-process command?
To refer to a variable inside the argument list of the Start-Process
command in PowerShell, you can use string interpolation or concatenation to include the variable's value in the command. Here are two examples:
- String Interpolation:
powershell$variable = "Value"
$argument = "Argument $variable"
Start-Process -FilePath "Executable.exe" -ArgumentList $argument
In this example, the value of $variable
is included inside the $argument
string using string interpolation ("Argument $variable"
). When passing the argument to Start-Process
, the variable's value will be substituted in the argument string.
- String Concatenation:
powershell$variable = "Value"
$argument = "Argument " + $variable
Start-Process -FilePath "Executable.exe" -ArgumentList $argument
In this example, the value of $variable
is concatenated with the "Argument "
string using the +
operator ("Argument " + $variable
). The resulting string is then passed as an argument to Start-Process
.
Both approaches achieve the same result of incorporating the variable's value within the argument list of Start-Process
. Choose the method that is more convenient or readable for your specific scenario.
It's important to note that when using string interpolation or concatenation, you should be cautious about potential security risks, such as injection vulnerabilities. Ensure that any user-supplied or untrusted values are properly sanitized or validated before including them in the command arguments.
