With no arguments it will wait to successfully finish all previous parts of an EVL job (in an EVS file) or in an EVL workflow (in an EWS file), i.e. act similar to standard Bash ‘wait’ command.

Fail (and cancel further job/workflow processing) if at least one component failed. Continue processing EVS/EWS file if all previous components/parts successfully finished.

EVS is EVL job definition file, for details see evl-evs(5). EWS is EVL workflow definition file, for details see evl-ews(5).

EVL workflow only:

When no <job>, <workflow> or <script> is specified, further processing will wait <time> for all previously fired parts (i.e. ‘Run’ commands) and fail if at least one of them fails.

When no <time> is specified, then wait forever.

<time> can be secified in seconds, minutes, hours or days, so suffix ‘s’, ‘m’, ‘h’ or ‘d’ need to be specified to the number. If no unit is specified, seconds are assumed.

When <job>, <workflow> or <script> is specified, it will wait for successful run of the job of the current project and of the current <odate>. Different <project> and/or <odate> can be specified by the options.


  ( <job>.evl | <workflow>.ewf | <script>.sh )
  [-p|--project=<project>] [-o|--odate=<odate> | -y|--yesterday]

  [-m|--myself [-o|--odate=<odate> | -y|--yesterday]]

EVL job

  1. Run EVL job in two steps:
    Read  file.json INPUT   evd/file.evd --text-input
    Map   INPUT     MAPPED  evd/file.evd evd/stage.evd evm/file.evm
    Write MAPPED    stage.parquet        evd/stage.evd
    Run   "impala \"refresh table stage;\""

EVL workflow

  1. Wait for myself (i.e. the same workflow yesterday) to finish:
    Wait --myself

    or the inother words:

    Wait --myself --yesterday

    or shortly also:

    Wait -my
  2. Wait for all jobs to finish, but at most 1 hour, then fail:
    Run file2stage.bills.evl update.bills.evl
    Run file2stage.invoices.evl
    Wait 1h
  3. Wait (forever) for successful run of the job ‘file2stage_example.evl’, then continue:
    Wait file2stage.example.evl
  4. Wait (at most 1 day) for the job ‘export_job.evl’ before continue:
    Wait 1d export_job.evl
  5. Wait (at most 120 minutes) for the job ‘sftp_billing.evl’ of the different project ‘billing’ (of current ODATE):
    Wait 120m sftp_billing.evl billing
  6. Wait (at most 300 seconds) for the job ‘sftp_billing.evl’ of the different project ‘billing’ of the 20200628}:
    Wait 300 sftp_billing.evl billing 20200628
  7. Wait (at most 6 hours) for previous run of current ‘EWF’ job. (Variable ‘ODATE_MINUS1’ has to be set by you.):
    # Wait for previous ODATE 
    Wait 6h $EWF_JOB_NAME.ewf $ODATE_MINUS1
