NAME

extrdata − Geoware Decompression Utility

SYNOPSIS

extrdata installdir [ −Ccase ] [ −Dnup ] [ −Pbindir ]

DESCRIPTION

extrdata is used to extract compressed and packed data files from the Geoware GMT Companion CD-ROM. Normally, the program is run by the installation script and no manual run is required. However, if you change your mind and want to extract more data after you have finished the installation then you must run it manually. The program can be used for both the Unix/Linux and the Windows distribution. Under Unix/Linux/Mac OS X it will write Bourne shell commands to stdout which can be saved to a file and executed when extrdata is completed (piping commands through sh is not recommended because of the output will interfere with the interactive session). Under Windows the same commands are executed using system calls. In both cases the current working directory must be the top directory on the CD-ROM and the programs extrdata, geobzip2 and grdzip, must be in your search path.
installdir

Give the top-level installation directory that was used when the Geoware Companion CD-ROM was first used to install the software and data. The default for that choice was $HOME/geoware (Unix/Linux) or C:\Geoware (Windows) but you may have specified a different directory. This argument must be the first argument before any of the optional switches.

−C

Here, case specifies which case we should use when addressing file names on the CD. Specify either L (lower case) or U (upper case). If no case is specified, extrdata will not change any filenames.

−D

Specify how many directory levels to go up before running the extraction [0].

−P

Give the bindir directory where the programs grdzip and geobzip2 can be found [Default relies on the system PATH]. SH EXAMPLES To run the extrdata utility to pull more data from the CD-ROM under Unix/Linux/Mac OSX, try

cd /mnt/cdrom (or something similar)
extrdata /Users/pwessel/geoware > /Users/pwessel/geoware/job.sh
sh /Users/pwessel/geoware/job.sh

while under Windows you will do
cd D:\
extrdata C:\Geoware
