найти файлы (find files)
Описание (Description)
The find utility shall recursively descend the directory
hierarchy from each file specified by path, evaluating a Boolean
expression composed of the primaries described in the OPERANDS
section for each file encountered. Each path operand shall be
evaluated unaltered as it was provided, including all trailing
<slash> characters; all pathnames for other files encountered in
the hierarchy shall consist of the concatenation of the current
path operand, a <slash> if the current path operand did not end
in one, and the filename relative to the path operand. The
relative portion shall contain no dot or dot-dot components, no
trailing <slash> characters, and only single <slash> characters
between pathname components.
The find utility shall be able to descend to arbitrary depths in
a file hierarchy and shall not fail due to path length
limitations (unless a path operand specified by the application
exceeds {PATH_MAX} requirements).
The find utility shall detect infinite loops; that is, entering a
previously visited directory that is an ancestor of the last file
encountered. When it detects an infinite loop, find shall write
a diagnostic message to standard error and shall either recover
its position in the hierarchy or terminate.
If a file is removed from or added to the directory hierarchy
being searched it is unspecified whether or not find includes
that file in its search.
