Examples of com.ajjpj.abase.proc.CliCommand

com.ajjpj.abase.proc.CliCommand
This utility class executes a command as a separate process, returning its output (i.e. stdout) as a list of strings, with each line as a separate element.
To guard the calling JVM against overflow, it limits the number of lines of output that are stored.
NB: This class executes the command *synchronously*, blocking until it returns. For long running commands, that may or may not be a problem for calling code.
