NAME

       mdm-run - run a command in parallel with mdm-master

SYNOPSIS

       mdm-run command
       mdm-sync command

DESCRIPTION

       mdm-run annotates command as a candidate for parallel execution.  If an mdm-master process
       is present (i.e., the environment  variable  MDM_CMD_SOCK  is  defined),  mdm-run  submits
       command to the mdm-master, and it exits when the master issues the command to an mdm-slave
       process (which may be connected to another terminal) for execution.  mdm-sync runs command
       in  place,  but  it  coordinates with mdm-master to ensure that executing command does not
       interfere with commands that are currently executing in parallel.

       If there is no mdm-master process present (i.e., the environment variable MDM_CMD_SOCK  is
       not  defined),  both mdm-run and mdm-sync simply run command as if you entered command all
       by itself.

       These programs are a part of the Middleman System (mdm).

OPTIONS

       Neither mdm-run nor mdm-sync accepts any options.

EXIT STATUS

       If there is no mdm-master process present, the exit status of mdm-run is the  exit  status
       of  command.   If  an  mdm-master  process is present, the exit status is 0 if and only if
       command is successfully issued to an mdm-slave process for execution.

       The exit status of mdm-sync is always the exit status of command.

ENVIRONMENT

       The mdm system uses the following environment variable  for  internal  communication,  and
       thus you should not try to set them yourself.

       MDM_CMD_SOCK
              mdm-run  uses  this  environment variable to decide whether a mdm-master process is
              present.
