The MOOSE environment can be modified by several environment variables: * `METHOD` - Determines the type of binary file created when compiling a MOOSE-based application: * `opt`: An optimized binary (the default) * `dbg`: A binary with no optimization that contains full debugging symbols * `oprof`: An optimized binary with debugging symbols * `METHODS` * A space separated list of the `METHOD`s used to build libMesh during the `update_and_rebuild_libmesh.sh` script. * `MOOSE_JOBS` * The number of simultaneous compile jobs to run when building libMesh * When using our redistributable package this number is automatically detected * `MOOSE_PROMPT` * If set to `true` before sourcing the MOOSE environment from our redistributable package then the BASH prompt for your console will be colored. * `MOOSE_JUMP` * If set to `true` before sourcing the MOOSE environment then [autojump](https://github.com/joelthelion/autojump) will be enabled. * `MOOSE_PPS_WIDTH` * Determines the max character width of the Console Postprocessor table. Set this variable to prevent wrapping. * `MOOSE_MPI_COMMAND` * Set this variable to override the MPI prefix used by the TestHarness. (Default: `mpiexec -host localhost`).
