08-14-2008 08:00 AM Quantum GIS 0.11.0, released last month, is a free geographic information system (GIS) application released under the GPL that runs on multiple platforms, including Linux. QGIS can read, edit, and export common GIS file formats. After installing it and using it to work with existing data layers available from official data repositories, performing common spatial analysis tasks, and sharing files and data with the commercial GIS products, I found QGIS has the potential to be a viable alternative to proprietary commercial GIS programs from the likes of ESRI and Intergraph/Geomedia.
Hi there can anyone help me to spot my mistake and please explain why it appears
My code :
#!/usr/bin/gawk -f
BEGIN { bytes =0}
{ temp=$(grep "datafeed\.php" | cut -d" " -f8)
bytes += temp}
END { printf "Number of bytes: %d\n", bytes }

HI. there
My 10 servers are running on 6.1-05-03 aix including NIM server
but my user want to update a TL (61-05-03 to 61-06-04)
if I Update a AIx version of TL .. is that change the SPOT of NIM server..
OR if I make a spot of AIX7.1 and Is that support AIX 6.1 AIX 5.3 Images

Hey
May be a dumb question
Can I use a SPOT which is at 5.3 TL6 to boot an LPAR (with 5.3 TL8) in to maintenance mode? Will it work ?
Is it mandatory that SPOT should be of same or higher version in such case?

I posted earlier with a problem it's here, I have edited the script a little and it tells me once more that the end of line is unexpected and I'm really lost with this one, thanks for any help.
The new version:

does somebody know about SPOT ?? any link about SPOT commands ?
i ve made a mistake during configuration, :mad:

the only shell was SPOT. :eek:
SPOT doesn t understand anything....
how do i work with SPOT ?
thanks in advance

grass-pg - PostgreSQL driver
PostgreSQL driver PostgreSQL driver in GRASS The driver name is 'pg'.
Creating a PostgreSQL database
A new database is created with 'createdb', see the PostgreSQL manual for details.
Connecting GRASS to PostgreSQL
# example for connecting to a PostgreSQL server:
db.connect driver=pg database="host=myserver.osgeo.org,dbname=mydb"
# password is asked interactively if not specified:
db.login user=myname [pass=secret]
db.connect -p
db.tables -p
Supported SQL commands
All SQL commands supported by PostgreSQL. It's not possible to use C-like escapes (with backslash like
etc) within SQL syntax.
Operators available in conditions
All SQL operators supported by PostgreSQL.
Adding an unique ID column
Import vector module require an unique ID column which can be generated as follows in a PostgreSQL table:
echo "
ALTER TABLE mytable ADD ID integer;
CREATE SEQUENCE mytable_seq;
UPDATE mytabe SET ID = nextval('mytable_seq');
DROP SEQUENCE mytable_seq;
" | db.execute
Attribute Converters
CSV import into PostgreSQL:
h copy
COPY t1 FROM 'filename' USING DELIMITERS ',';
pg2xbase: DBF to PostgreSQL converter.
Geometry import from PostgreSQL table
v.in.db creates a new vector (points) map from a database table containing coordinates. See here for examples.
PostGIS: PostgreSQL with vector geometry
PostGIS: adds geographic object support to PostgreSQL.
Example: Import from PostGIS
In an existing PostGIS database, create the following table:
CREATE TABLE test
(
id serial NOT NULL,
mytime timestamp DEFAULT now(),
text varchar,
wkb_geometry geometry,
CONSTRAINT test_pkey PRIMARY KEY (id)
) WITHOUT OIDS;
# insert value
INSERT INTO test (text, wkb_geometry)
VALUES ('Name',geometryFromText('POLYGON((600000 200000,650000
200000,650000 250000,600000 250000,600000 200000))',-1));
# register geometry column
select AddGeometryColumn ('postgis', 'test', 'geometry', -1, 'GEOMETRY', 2);
GRASS can import this PostGIS polygon map as follows:
v.in.ogr dsn="PG:host=localhost dbname=postgis user=neteler" layer=test
output=test type=boundary,centroid
v.db.select test
v.info -t test
Geometry Converters
PostGIS with shp2pgsql:
shp2pgsql -D lakespy2 lakespy2 test > lakespy2.sql
e00pg: E00 to PostGIS filter, see also v.in.e00.
GDAL/OGR ogrinfo and ogr2ogr: GIS vector format converter and library, e.g. ArcInfo or SHAPE to PostGIS.
ogr2ogr -f "PostgreSQL" shapefile ??
