- This (/usr/gnu) is the GNU directory.

- This directory and its contents are obsolete. For newer versions

- ------------------------------------------------------------------------
- Silicon Graphics, Inc. (SGI) is not officially supporting this
- software. Please don't call us for support. Instead, SGI provides
- GNU as an optional software package that can be conveniently
- installed by customers who wish to do it. Customers who wish
- to install and use this software, will need to add /usr/gnu/bin
- to their PATH, and add /usr/gnu/catman:/usr/gnu/man to their
- MANPATH. This is not done by default.
-
- We encourage users who benefit from this software to donate
- money or equipment to the FSF, and to support free software.
- See http://www.gnu.org/ for details.
-
- This is not the full GNU distribution. It only contains selected
- GNU packages. The intent is to expand this with time. If you
- wish to have a package that's not included here, you may download
- it from the official GNU site ftp://prep.ai.mit.edu/pub/gnu/
- or one of its mirrors (see http://www.gnu.org/order/ftp.html)
- and build it yourself.
-
- This software is provided "as is", and including full source, as
- a result of extensive and repeating customer requests to make GNU
- software more easily and conveniently available on SGI systems.
-
- SGI disclaims all warranties with regard to this software,
- including all implied warranties of merchantability and fitness,
- in no event shall SGI be liable for any special, indirect or
- consequential damages or any damages whatsoever resulting from

- negligence or other tortious action, arising out of or in
- connection with the use or performance of this software.

- Some Hints:
-
- o Some GNU commands have the same name as their SGI counterparts
- and in some cases slightly different options and behavior.
-
- If you have /usr/gnu/bin in your path and find it confusing
- try 'which command' where `command' is the command name whose
- behavior you find confusing.
-
- o Three scripts are provided under /usr/gnu/bin for your
- convenience and to help avoid confusion:
-
- 1) gman
- 2) sman
- 3) gnu
-
- Their function is:
-
- gman [-section] some_command
- Will force a GNU man page display for `some_command'
- Regardless of your current PATH.
-
- sman [-section] some_command
- Will force an SGI man page display for `some_command'
- Regardless of your current PATH.
-
- gnu [some_command args...]
- Will call `some_command' with the provided arguments
- `args...' in the GNU universe, without changing your
- permanent settings (PATH etc.)
-
- When called without arguments, `gnu' will give you a
- shell (based on the $SHELL environment variable, or
- your preferred login shell if $SHELL isn't set)
- under the GNU universe. Use `exit' to exit this shell.
-
- NOTE:
- shell internal commands, like `cd' will not be covered by any of
- these scripts. Check your preferred shell documentation for a list
- of internal commands.
-
- A few notable SGI/GNU incompatibilities
-
- This is not a comprehensive list. Please refer to the outputs of
- gman vs. sman for details on every command interface. A few notable
- differences are listed here.
-
- GNU commands have an extended common options handling. Long options
- are supported using --option (double dash) and standard options
- like --help, and --version are supported in most cases.
-
- GNU chmod/chown -R do not follow symbolic links by default. SGI
- commands which originated from SVR4 do follow symlinks by default.
-
- SGI find has a -local option to skip remote mounted directories
- GNU doesn't.
-
- GNU grep/egrep/fgrep are actually one command. SGI versions are separate.
-
- GNU and SGI have slightly different conventions for storing I18N
- contents. GNU utils which support I18N have more language catalogues.
-
- GNU find has the current directory and the '-print' option set by
- default.
-
- GNU tar has many extensions, including '-z' for compress/decompress
- -S for supporting holy (sparse) files and more.
-
- GNU sort is slower than the SGI sort but takes much less memory
- to run.
