runCommand -package:wai-app-static -package:libmpd -package:shake-plus -package:pandoc-plot -package:xmonad-contrib -package:process
Runs a command using the shell.
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.
runCommand1 foo = runCommand [foo =: 1]
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.
Default to
True. Should you run command line actions, set to
False to skip actions whose output streams and exit code are
not used. Useful for profiling the non-command portion of the build
system.
