.SH "NAME"
pegasus-run \- executes a workflow that has been planned using *pegasus\-plan*\&.
.SH "SYNOPSIS"
.sp
.nf
\fBpegasus\-run\fR [\fB\-D\fR\fIproperty=value\fR\&...][\fB\-c\fR \fIpropsfile\fR][\fB\-d\fR \fIlevel\fR]
            [\fB\-v][\fR\-\-grid*][rundir]
.fi
.SH "DESCRIPTION"
.sp
The \fBpegasus\-run\fR command executes a workflow that has been planned using \fBpegasus\-plan\fR\&. By default pegasus\-run can be invoked either in the planned directory with no options and arguments or just the full path to the run directory\&. \fBpegasus\-run\fR also can be used to resubmit a failed workflow by running the same command again\&.
.SH "OPTIONS"
.sp
By default \fBpegasus\-run\fR does not require any options or arguments if invoked from within the planned workflow directory\&. If running the command outside the workflow directory then a full path to the workflow directory needs to be specified\&.
.sp
\fBpegasus\-run\fR takes the following options
.PP
\fB\-D\fR\fIproperty=value\fR
.RS 4
The
\fB\-D\fR
option allows an advanced user to override certain properties which influence
\fBpegasus\-run\fR\&. One may set several CLI properties by giving this option multiple times\&.
.sp
The
\fB\-D\fR
option(s) must be the first option on the command line\&. CLI properties take precedence over the file\-based properties of the same key\&.
.sp
See the
\fBPROPERTIES\fR
section below\&.
.RE
.PP
\fB\-c\fR \fIpropsfile\fR, \fB\-\-conf\fR \fIpropsfile\fR
.RS 4
Provide a property file to override the default Pegasus properties file from the planning directory\&. Ordinary users do not need to use this option unless the specifically want to override several properties
.RE
.PP
\fB\-d\fR \fIlevel\fR, \fB\-\-debug\fR \fIlevel\fR
.RS 4
Set the debug level for the client\&. Default is 0\&.
.RE
.PP
\fB\-v\fR, \fB\-\-verbose\fR
.RS 4
Raises debug level\&. Each invocation increase the level by 1\&.
.RE
.PP
\fB\-\-grid\fR
.RS 4
Enable grid checks to see if your submit machine is GRID enabled\&.
.RE
.PP
\fIrundir\fR
.RS 4
Is the full qualified path to the base directory containing the planned workflow DAG and submit files\&. This is optional if the
\fBpegasus\-run\fR
command is invoked from within the run directory\&.
.RE
.SH "RETURN VALUE"
.sp
If the workflow is submitted for execution \fBpegasus\-run\fR returns with an exit code of 0\&. However, in case of error, a non\-zero return value indicates problems\&. An error message clearly marks the cause\&.
.SH "FILES"
.sp
The following files are created, opened or written to:
.PP
\fBbraindump\fR
.RS 4
This file is located in the rundir\&. pegasus\-run uses this file to find out paths to several other files, properties configurations etc\&.
.RE
.PP
\fBpegasus\&.?????????\&.properties\fR
.RS 4
This file is located in the rundir\&. pegasus\-run uses this properties file by default to configure its internal settings\&.
.RE
.PP
\fBworkflowname\&.dag\fR
.RS 4
pegasus\-run uses the workflowname\&.dag or workflowname\&.sh file and submits it either to condor for execution or runs it locally in a shell environment
.RE
.SH "PROPERTIES"
.sp
pegasus\-run reads its properties from several locations\&.
.PP
\fBRUNDIR/pegasus\&.??????????\&.properties\fR
.RS 4
The default location for pegasus\-run to read the properties from
.RE
.PP
\fB\-\-conf propfile\fR
.RS 4
properties file provided in the conf option replaces the default properties file used\&.
.RE
.PP
\fB$HOME/\&.pegasusrc\fR
.RS 4
will be used if neither default rundir properties or \-\-conf propertiesfile are found\&.
.sp
Additionally properties can be provided individually using the
\fB\-Dpropkey\fR=\fIpropvalue\fR
option on the command line before all other options\&. These properties will override properties provided using either
\fB\-\-conf\fR
or
\fIRUNDIR/pegasus\&.???????\&.properties\fR
or the
\fI$HOME/\&.pegasusrc\fR
.sp
The merge logic is CONF PROPERTIES || DEFAULT RUNDIR PROPERTIES || PEGASUSRC overriden by Command line properties
.RE
.SH "ENVIRONMENT VARIABLES"
.PP
\fBPATH\fR
.RS 4
The path variable is used to locate binaries for condor\-submit\-dag, condor\-dagman, condor\-submit,pegasus\-submit\-dag, pegasus\-dagman and pegasus\-monitord
