paths

Prototype: paths

Description: Defines an array path with common paths to standard binaries, and classes for defined and existing paths.

If the current platform knows that binary XYZ should be present, _stdlib_has_path_XYZ is defined. Furthermore, if XYZ is actually present (i.e. the binary exists) in the expected location, _stdlib_path_exists_XYZ is defined.

Example:

bundle agent repair_newlines(filename)
{
commands:
  _stdlib_path_exists_sed::
     "$(path[sed])"
       args => "-i 's/^M//' $(filename)"
}

Implementation:

bundle common paths
{
  vars:

      #
      # Common full pathname of commands for OS
      #
