  25 # Script
  26 #     foamEtcFile
  27 #
  28 # Description
  29 #     Locate user/group/shipped file with semantics similar to the
  30 #     ~OpenFOAM/fileName expansion.
  31 #
  32 #     The -mode option can be used to allow chaining from
  33 #     personal settings to site-wide settings.
  34 #
  35 #     For example, within the user ~/.OpenFOAM/<VER>/prefs.sh:
  36 #     \code
  37 #        foamPrefs=`$WM_PROJECT_DIR/bin/foamEtcFile -m go prefs.sh` \
  38 #            && _foamSource $foamPrefs
  39 #     \endcode
  40 #
  41 # Note
  42 #     This script must exist in <foamInstall>/OpenFOAM-<VERSION>/bin/
  43 #     or <foamInstall>/openfoam<VERSION>/bin/ (for the debian version)
  44 #

  55 options:
  56   -list             list the directories to be searched
  57   -mode <mode>      any combination of u(user), g(group), o(other)
  58   -prefix <dir>     specify an alternative installation prefix
  59   -quiet            suppress all normal output
  60   -silent           suppress all stderr output
  61   -version <ver>    specify an alternative OpenFOAM version
  62                     in the form Maj.Min.Rev (eg, 1.7.0)
  63   -help             print the usage
  64
  65   Locate user/group/shipped file with semantics similar to the
  66   ~OpenFOAM/fileName expansion.
  67
  68   The options can also be specified as a single character
  69   (eg, '-q' instead of '-quiet'), but must not be grouped.
  70
  71   Exit status
  72       0  when the file is found. Print resolved path to stdout.
  73       1  for miscellaneous errors.
  74       2  when the file is not found.
