NAME

       condor_run - HTCondor Manual

       Submit a shell command-line as an HTCondor job

SYNOPSIS

       condor_run [-u universe] [-a submitcmd] "shell command"

DESCRIPTION

       condor_run  bundles a shell command line into an HTCondor job and submits the job. The condor_run command
       waits for the HTCondor job to complete, writes the job's output to the terminal, and exits with the  exit
       status of the HTCondor job. No output appears until the job completes.

       Enclose  the  shell  command  line  in  double  quote  marks,  so  it may be passed to condor_run without
       modification. condor_run will not read input from the terminal while  the  job  executes.  If  the  shell
       command line requires input, redirect the input from a file, as illustrated by the example

          $ condor_run "myprog < input.data"

       condor_run jobs rely on a shared file system for access to any necessary input files. The current working
       directory of the job must be accessible to the machine within the HTCondor pool where the job runs.

       Specialized  environment  variables may be used to specify requirements for the machine where the job may
       run.

          CONDOR_ARCH
                 Specifies the architecture of the required platform. Values  will  be  the  same  as  the  Arch
                 machine ClassAd attribute.

          CONDOR_OPSYS
                 Specifies  the  operating system of the required platform. Values will be the same as the OpSys
                 machine ClassAd attribute.

          CONDOR_REQUIREMENTS
                 Specifies any additional requirements for the HTCondor job. It is recommended  that  the  value
                 defined for CONDOR_REQUIREMENTS be enclosed in parenthesis.

       When one or more of these environment variables is specified, the job is submitted with:

          Requirements = $CONDOR_REQUIREMENTS && Arch == $CONDOR_ARCH && OpSys == $CONDOR_OPSYS

       Without these environment variables, the job receives the default requirements expression, which requests
       a machine of the same platform as the machine on which condor_run is executed.

       All  environment  variables  set  when  condor_run is executed will be included in the environment of the
       HTCondor job.

       condor_run removes the HTCondor job from the queue and deletes its  temporary  files,  if  condor_run  is
       killed before the HTCondor job completes.

OPTIONS

          -u universe
                 Submit the job under the specified universe. The default is vanilla.  While any universe may be
                 specified, only the vanilla, scheduler, and local universes result in a submit description file
                 that may work properly.

          -a submitcmd
                 Add the specified submit command to the implied submit description file for the job. To include
                 spaces  within  submitcmd,  enclose  the  submit command in double quote marks. And, to include
                 double quote marks within submitcmd, enclose the submit command in single quote marks.

EXAMPLES

       condor_run may be used to compile an executable on a different platform. As an  example,  first  set  the
       environment variables for the required platform:

          $ export CONDOR_ARCH="SUN4u"
          $ export CONDOR_OPSYS="SOLARIS28"

       Then, use condor_run to submit the compilation as in the following two examples.

          $ condor_run "f77 -O -o myprog myprog.f"

       or

          $ condor_run "make"

FILES

       condor_run  creates  the following temporary files in the user's working directory. The placeholder <pid>
       is replaced by the process id of condor_run.

       .condor_run.<pid>
              A shell script containing the shell command line.

       .condor_submit.<pid>
              The submit description file for the job.

       .condor_log.<pid>
              The HTCondor job's log file; it is monitored by condor_run, to determine when the job exits.

       .condor_out.<pid>
              The output of the HTCondor job before it is output to the terminal.

       .condor_error.<pid>
              Any error messages for the HTCondor job before they are output to the terminal.

       condor_run removes these files when the job completes. However, if condor_run fails, it is possible  that
       these files will remain in the user's working directory, and the HTCondor job may remain in the queue.

GENERAL REMARKS

       condor_run  is  intended  for  submitting simple shell command lines to HTCondor. It does not provide the
       full functionality of condor_submit. Therefore, some condor_submit errors and system failures may not  be
       handled correctly.

       All  processes  specified  within  the  single  shell command line will be executed on the single machine
       matched with the job. HTCondor will not distribute multiple processes  of  a  command  line  pipe  across
       multiple machines.

       condor_run will use the shell specified in the SHELL
         environment variable, if one exists. Otherwise, it will use /bin/sh to execute the shell command-line.

       By  default,  condor_run  expects  Perl to be installed in /usr/bin/perl. If Perl is installed in another
       path, ask the Condor administrator to edit the path in the condor_run script,  or  explicitly  call  Perl
       from the command line:

          $ perl path-to-condor/bin/condor_run "shell-cmd"

EXIT STATUS

       condor_run  exits  with  a  status value of 0 (zero) upon complete success. The exit status of condor_run
       will be non-zero upon failure.  The exit status in the case of a single error due to a system  call  will
       be the error number (errno) of the failed call.
