oldfind.1 . -name file.txt -exec egrep.1 -H key {} ;
search for files in a directory hierarchy
-H     Do not follow symbolic links, except while processing  the  command  line  arguments.   When  find
       examines  or  prints  information  about  files,  the  information  used  shall  be taken from the
       properties of the symbolic link itself.   The only exception to this  behaviour  is  when  a  file
       specified  on  the  command  line  is  a  symbolic  link,  and the link can be resolved.  For that
       situation, the information used is taken from whatever the link points to (that is,  the  link  is
       followed).   The information about the link itself is used as a fallback if the file pointed to by
       the symbolic link cannot be examined.  If -H is in effect and one of the paths  specified  on  the
       command  line  is  a symbolic link to a directory, the contents of that directory will be examined
       (though of course -maxdepth 0 would prevent this).

If more than one of -H, -L and -P is specified, each overrides the others; the last one appearing on  the
command  line  takes effect.  Since it is the default, the -P option should be considered to be in effect
unless either -H or -L is specified.

GNU find frequently stats files during the processing of the command line itself,  before  any  searching
has  begun.   These  options  also  affect  how those arguments are processed.  Specifically, there are a
number of tests that compare  files  listed  on  the  command  line  against  a  file  we  are  currently
considering.   In  each  case, the file specified on the command line will have been examined and some of
its properties will have been saved.  If the named file is in fact a symbolic link, and the -P option  is
in effect (or if neither -H nor -L were specified), the information used for the comparison will be taken
from the properties of the symbolic link.  Otherwise, it will be taken from the properties  of  the  file
the  link  points to.  If find cannot follow the link (for example because it has insufficient privileges
or the link points to a nonexistent file) the properties of the link itself will be used.

When the -H or -L options are in effect, any symbolic links listed as the  argument  of  -newer  will  be
dereferenced,  and the timestamp will be taken from the file to which the symbolic link points.  The same
consideration applies to -newerXY, -anewer and -cnewer.

The -follow option has a similar effect to -L, though it takes effect at the point where it appears (that
is, if -L is not used but -follow is, any symbolic links appearing after -follow on the command line will
be dereferenced, and those before it will not).
Commands separated  by  a ; are executed sequentially; the shell waits for each command to terminate in turn.  The
return status is the exit status of the last command executed.
