Runs a command using the shell.
Run a Command.
Run an external command on the specified DotRepr. Remember to use hSetBinaryMode on the Handle for the output function if necessary. If the command was unsuccessful, then a GraphvizException is thrown. For performance reasons, a temporary file is used to store the generated Dot code. As such, this is only suitable for local commands.
Given a list of command/action pairs, prompt the user to choose a command using dmenu and return the corresponding action.
Run with the given middleware and parsing options from the command line. Since 2.0.1
runCommand1 foo = runCommand [foo =: 1]
Given the name of a command from defaultCommands, return the corresponding action (or the null action if the command is not found).
Given a list of command/action pairs, prompt the user to choose a command using dmenu-compatible launcher and return the corresponding action. See X.U.Dmenu for compatible launchers.
Called before a command is about to run. The first argument is the step index and the second is a string representing the command about to be run.
Currently, we support including only one RunCommandTarget block, which specifies either an array of InstanceIds or a tag.
Can be either tag: tag-key or InstanceIds.
If Key is tag: tag-key, Values is a list of tag values. If Key is InstanceIds, Values is a list of Amazon EC2 instance IDs.
This parameter contains the criteria (either InstanceIds or a tag) used to specify which EC2 instances are to be sent the command. See: newRunCommandParameters smart constructor.
Information about the EC2 instances that are to be sent the command, specified as key-value pairs. Each RunCommandTarget block can include only one key, but this key may specify multiple values. See: newRunCommandTarget smart constructor.
