## lotus-worker run
```
NAME:
   lotus-worker run - Start lotus worker

USAGE:
   lotus-worker run [command options] [arguments...]

DESCRIPTION:
   Run lotus-worker.

   --external-pc2 can be used to compute the PreCommit2 inputs externally.
   The flag behaves similarly to the related lotus-worker flag, using it in
   lotus-bench may be useful for testing if the external PreCommit2 command is
   invoked correctly.

   The command will be called with a number of environment variables set:
   * EXTSEAL_PC2_SECTOR_NUM: the sector number
   * EXTSEAL_PC2_SECTOR_MINER: the miner id
   * EXTSEAL_PC2_PROOF_TYPE: the proof type
   * EXTSEAL_PC2_SECTOR_SIZE: the sector size in bytes
   * EXTSEAL_PC2_CACHE: the path to the cache directory
   * EXTSEAL_PC2_SEALED: the path to the sealed sector file (initialized with unsealed data by the caller)
   * EXTSEAL_PC2_PC1OUT: output from rust-fil-proofs precommit1 phase (base64 encoded json)

   The command is expected to:
   * Create cache sc-02-data-tree-r* files
   * Create cache sc-02-data-tree-c* files
   * Create cache p_aux / t_aux files
   * Transform the sealed file in place

   Example invocation of lotus-bench as external executor:
   './lotus-bench simple precommit2 --sector-size $EXTSEAL_PC2_SECTOR_SIZE $EXTSEAL_PC2_SEALED $EXTSEAL_PC2_CACHE $EXTSEAL_PC2_PC1OUT'
