SimpleExec
Runs external commands.
$ dotnet add package SimpleExec
SimpleExec is a .NET library that runs external commands. It wraps System.Diagnostics.Process to make things easier.
SimpleExec intentionally does not invoke the system shell.
By default, the command is echoed to standard error (stderr) for visibility.
Platform support: .NET Standard 2.1 and later.
using static SimpleExec.Command;Run("foo.exe", "arg1 arg2");Run("foo.exe");
Run("foo.exe", "arg1 arg2");
Run("foo.exe", new[] { "arg1", "arg2" });
await RunAsync("foo.exe");
await RunAsync("foo.exe", "arg1 arg2");
await RunAsync("foo.exe", new[] { "arg1", "arg2" });var (standardOutput1, standardError1) = await ReadAsync("foo.exe");
var (standardOutput2, standardError2) = await ReadAsync("foo.exe", "arg1 arg2");
var (standardOutput3, standardError3) = await ReadAsync("foo.exe", new[] { "arg1", "arg2" });string workingDirectory = "",

CancellationToken cancellationToken = default,If the command has a non-zero exit code, an ExitCodeException is thrown with an int ExitCode property and a message in the form of:
$"The process exited with code {ExitCode}."In the case of ReadAsync, an ExitCodeReadException is thrown, which inherits from ExitCodeException, and has string Out and Error properties, representing standard out (stdout) and standard error (stderr), and a message in the form of:
$@"The process exited with code {ExitCode}.
Standard Output:
{Out}
Standard Error:
{Error}"The throwing of exceptions for specific non-zero exit codes can be suppressed by passing a delegate to handleExitCode which returns true when it has handled the exit code and default exit code handling should be suppressed, and returns false otherwise. For example:
Run("ROBOCOPY", "from to", handleExitCode: code => code < 8);Note that it may be useful to record the exit code. For example:
var exitCode = 0;
Run("ROBOCOPY", "from to", handleExitCode: code => (exitCode = code) < 8);
