    [WP] (issue14): replace echo -e by printf · b6000ac0
    we7765 authored
    The echo shell builtin of the traditional Bourne Shell does not recognize the
    -e option. Better use printf in this case.
    
    From the POSIX manual for printf:
    
    RATIONALE
      The printf utility was added to provide functionality that has histori-
      cally been provided by echo. However, due to irreconcilable differ-
      ences in the various versions of echo extant, the version has few special
      features, leaving those to this new printf utility, which is based on one in
      the Ninth Edition system.
