B9.B9Exec

This modules contains support for external command execution.

Since: 0.5.65

Documentation

cmd :: CommandIO e => String -> Eff e ()

Execute the given shell command.

If isInteractive is true, the standard-in will be passed to the external command, and all output of the program will be directed to standard-out.

The command and the output is either logged to the logfile with traceL or errorL or written to stdout.

If the command exists with non-zero exit code, the current process exists with the same exit code.

Since: 0.5.65

hostCmdEither

Arguments

:: CommandIO e

=> HostCommandStdin

A HostCommandStdin to define standard input. If the value is HostCommandInheritStdin then **also stdout and stderr** will be redirected to the Inherited file descriptors.

-> String

The shell command to execute.

-> Maybe CommandTimeout

An optional CommandTimeout

-> Eff e (Either CommandTimeout ExitCode)

Run a shell command defined by a string and optionally interrupt the command after a given time has elapsed. This is only useful for non-interactive commands.

Since: 1.0.0

hostCmd

Arguments

:: (CommandIO e, Member ExcB9 e)

=> String

The shell command to execute.

-> Maybe CommandTimeout

An optional CommandTimeout

-> Eff e Bool

An action that performs the shell command and returns True on success

Run a shell command defined by a string and optionally interrupt the command after a given time has elapsed. If the shell command did not exit with ExitSuccess, or the timer elapsed, a B9Error is thrown.

This is only useful for non-interactive commands.

Since: 1.0.0

hostCmdStdIn

Arguments

:: (CommandIO e, Member ExcB9 e)

=> HostCommandStdin

A HostCommandStdin to define standard input. If the value is HostCommandInheritStdin then **also stdout and stderr** will be redirected to the Inherited file descriptors.

-> String

The shell command to execute.

-> Maybe CommandTimeout

An optional CommandTimeout

-> Eff e Bool

An action that performs the shell command and returns True on success

Like hostCmd but with std-input attached.
