There are some commands and programs that came with GNU packages that would replace standard ones provided by Sun or HP. These have been installed with a g- prefix to avoid conflicting with the vendor's (SUN/HP) own versions. If you don't like the fact that simple commands like "du" are not consistent between our Suns and HPs, or if you want a "cp" command that can copy directory trees without messing up time stamps or symbolic links, then you might want to select the GNU versions of these common unix utilities. To do this, you will need to select the ones you want by setting up aliases. For example, if you aliased "find" to "gfind", you would get a more sensible and consistent version of the find utility. Or you could just type "gfind" instead of "find" whenever you want to run the GNU version.
There are good reasons to choose the Gnu versions, For example:
- block sizes from `gdu' will always be in 1024-byte blocks, whether on a Sun or an HP
- `gdf' will figure out what physical disk a directory is located on (as will `bdf')
- all of the Gnu utilities accept friendlier `--' command line options (like
--help) in addition to the regular single letter `-' style options.
- many of the Gnu utilities are faster than Sun's or HP's versions
- in a recent test, Gnu's utilities proved more robust (lessy buggy or likely to crash) than commercial suppliers' software.
