I want to export one certain page from a pdf document to an image and automatically fill the page number in the file name. When I run the following code:
gs \
-sDEVICE=jpeg \
-o outfile-%03.jpeg \
-dFirstPage=12 \
-dLastPage=12 \
wo.pdf
I get: outfile-001.jpeg instead of outfile-012.jpeg.
I've wrote a bash script for the job:
function extract_nth_page(){
printf -v j "outfile-%05g.png" $1
echo $j
gs -q -dNOPAUSE -sDEVICE=png16m -r600 -dFirstPage=$1 -dLastPage=$1 -sOutputFile=$j $2 -c quit
return 0
}
# Extracts page number 42 from myFile.pdf to outfile-00042.png
extract_nth_page 42 myFile.pdf

There are variables that I need to change and run sequentially within certain codes.For example, the ionex_list variable looks like this and i need to change this in a loop. I have 3 variable files like this and 9 pieces of data in a row (ionex_list,receiver_ids,data_record).
ionex_list data_record
jplg0910.19i.Z ISTA00TUR_R_20190910000_01D_30S_MO.crx.gz
jplg0920.19i.Z ISTA00TUR_R_20190920000_01D_30S_MO.crx.gz
... ...
jplg0980.19i.Z ISTA00TUR_R_20190980000_01D_30S_MO.crx.gz
jplg0990.19i.Z ISTA00TUR_R_20190990000_01D_30S_MO.crx.gz
For example, I need to show ISTA00TUR_R_20190910000_01D_30S_MO.crx.gz as -dataFile in rnxEditGde.py, but I get the error "File: "/y2019/d091" does not exist" and I cannot show the path. these .gz files are a few directories under from the directory I'm working in. Since I couldn't pass the rnxEditGde.py part, I can't see if the codes below work properly.
dir=`pwd`
function pl {
sed -n "$1p" $2
}
for j in {091..099}; do
ids=$(pl $j receiver_ids)
ionex=$(pl $j ionex_list)

I am looking to run multiple instances of a command line script at the same time. I am new to this concept of "multi-threading" so am at bit of a loss as to why I am seeing the things that I am seeing.
I have tried to execute the sub-processing in two different ways:
1 - Using multiple calls of Popen without a communicate until the end:
command = 'raster2pgsql -I -C -e -s 26911 %s -t 100x100 -F p839.%s_image_sum_sum1 | psql -U david -d projects -h pg3' % (workspace + '\\r_sumsum1{}'.format(i), str(i))
process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
command = 'raster2pgsql -I -C -e -s 26911 %s -t 100x100 -F p839.%s_image_sum_sum2 | psql -U david -d projects -h pg3' % (workspace + '\\r_sumsum2{}'.format(i), str(i))
process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
command = 'raster2pgsql -I -C -e -s 26911 %s -t 100x100 -F p839.%s_image_sum_sum3 | psql -U david -d projects -h pg3' % (workspace + '\\r_sumsum3{}'.format(i), str(i))
process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
(stdoutdata, stderrdata) = process.communicate()
this starts up each of the command line item but only completes the last entry leaving the other 2 hanging.
2 - Attempting to implement an example from Python threading multiple bash subprocesses? but nothing happens except for a printout of the commands (program hangs with no command line arguments running as observed in windows task manager:
import threading
import Queue
import commands
import time
workspace = r'F:\Processing\SM'
image = 't08r_e'
image_name = (image.split('.'))[0]
i = 0
process_image_tif = workspace + '\\{}{}.tif'.format((image.split('r'))[0], str(i))
# thread class to run a command
class ExampleThread(threading.Thread):
def __init__(self, cmd, queue):
threading.Thread.__init__(self)
self.cmd = cmd
self.queue = queue
def run(self):
# execute the command, queue the result
(status, output) = commands.getstatusoutput(self.cmd)
self.queue.put((self.cmd, output, status))
# queue where results are placed
result_queue = Queue.Queue()
# define the commands to be run in parallel, run them
cmds = ['raster2pgsql -I -C -e -s 26911 %s -t 100x100 -F p839.%s_image_sum_sum1 | psql -U david -d projects -h pg3' % (workspace + '\\r_sumsum1{}'.format(i), str(i)),
'raster2pgsql -I -C -e -s 26911 %s -t 100x100 -F p839.%s_image_sum_sum2 | psql -U david -d projects -h pg3' % (workspace + '\\r_sumsum2{}'.format(i), str(i)),
'raster2pgsql -I -C -e -s 26911 %s -t 100x100 -F p839.%s_image_sum_sum3 | psql -U david -d projects -h pg3' % (workspace + '\\r_sumsum3{}'.format(i), str(i)),
]
for cmd in cmds:
thread = ExampleThread(cmd, result_queue)
thread.start()
# print results as we get them
while threading.active_count() > 1 or not result_queue.empty():
while not result_queue.empty():
(cmd, output, status) = result_queue.get()
print(cmd)
print(output)
How can I run all of these commands at the same time achieving a result at the end? I am running in windows, pyhton 2.7.
My first try didn't work because of the repeated definitions of stdout and sterror. Removing these definitions causes expected behavior.
I am receiving the email from the following CRON job but with a blank file attached. I have checked the /home/XXXXXX/public_html/tmp/ directory and a good tqhsa_hikashop_order.txt file is created in that /tmp/ folder but the one attached to the email that I receive is empty.
mysql --database=XXXXXXXX_jml_6UCHadruwR8veju3 -u XXXXXXXX_8eh6Nu --password=fRa6r7wRerEtuzud -B -e "SELECT order_number, order_created, order_invoice_number, order_full_price, order_discount_code, order_discount_price, order_payment_method, order_payment_price FROM tqhsa_hikashop_order;" > /home/XXXXXXXX/public_html/tmp/tqhsa_hikashop_order.txt | mail -s "Daily Discount Table Dump" -a /home/XXXXXXXX/public_html/tmp/tqhsa_hikashop_order.txt luke#example.com
Any ideas why the good text file is not being attached?
You need to ensure that your first command finishes before running the second, so that the file exists on disk.
So essentially replace the | with a &&:
mysql \
--database=XXXXXXXX_jml_6UCHadruwR8veju3 \
-u XXXXXXXX_8eh6Nu \
--password=fRa6r7wRerEtuzud \
-B \
-e "SELECT order_number, order_created, order_invoice_number, order_full_price, order_discount_code, order_discount_price, order_payment_method, order_payment_price FROM tqhsa_hikashop_order;" > /home/XXXXXXXX/public_html/tmp/tqhsa_hikashop_order.txt \
&& \
mail \
-s "Daily Discount Table Dump" \
-a /home/XXXXXXXX/public_html/tmp/tqhsa_hikashop_order.txt luke#example.com
To illustrate using an example:
myuser#myshell:~ $ echo "testing" > testy.txt | cat testy.txt
cat: testy.txt: No such file or directory
myuser#myshell:~ $ echo "testing" > testy.txt && cat testy.txt
testing
Sorry, I'm from Brazil and my english is not fluent.
I wanna concatenate 20 files using a shellscript through cat command. However when I run it from a file, all content of files are showed on the screen.
When I run it directly from terminal, works perfectly.
That's my code above:
#!/usr/bin/ksh
set -x -a
. /PROD/INCLUDE/include.prod
DATE=`date +'%Y%m%d%H%M%S'`
FINAL_NAME=$1
# check if all paremeters are passed
if [ -z $FINAL_NAME ]; then
echo "Please pass the final name as parameter"
exit 1
fi
# concatenate files
cat $DIRFILE/AI6LM760_AI6_CF2_SLOTP01* $DIRFILE/AI6LM761_AI6_CF2_SLOTP02* $DIRFILE/AI6LM763_AI6_CF2_SLOTP04* \
$DIRFILE/AI6LM764_AI6_CF2_SLOTP05* $DIRFILE/AI6LM765_AI6_CF2_SLOTP06* $DIRFILE/AI6LM766_AI6_CF2_SLOTP07* \
$DIRFILE/AI6LM767_AI6_CF2_SLOTP08* $DIRFILE/AI6LM768_AI6_CF2_SLOTP09* $DIRFILE/AI6LM769_AI6_CF2_SLOTP10* \
$DIRFILE/AI6LM770_AI6_CF2_SLOTP11* $DIRFILE/AI6LM771_AI6_CF2_SLOTP12* $DIRFILE/AI6LM772_AI6_CF2_SLOTP13* \
$DIRFILE/AI6LM773_AI6_CF2_SLOTP14* $DIRFILE/AI6LM774_AI6_CF2_SLOTP15* $DIRFILE/AI6LM775_AI6_CF2_SLOTP16* \
$DIRFILE/AI6LM776_AI6_CF2_SLOTP17* $DIRFILE/AI6LM777_AI6_CF2_SLOTP18* $DIRFILE/AI6LM778_AI6_CF2_SLOTP19* \
$DIRFILE/AI6LM779_AI6_CF2_SLOTP20* > CF2_FINAL_TEMP
mv $DIRFILE/CF2_FINAL_TEMP $DIRFILE/$FINAL_NAME
I solved the problem putting the cat block inside a function, and redirecting stdout to the final file.
Ex:
concatenate()
I created a Garmin map from my own OSM files (using JOSM and my own GPS records, no input from Openstreetmap).
The whole process run well, but I have just a little problem : when I load the final map to Basecamp, the name of this map is empty (blank).
Any idea ?
Here is the code. Before, some variables :
PREFIX=640000
ORIGINALNAME=$(echo ${PREFIX}00)
NAME=$(echo ${PREFIX}01)
ID_PUBLIC=64
DIR="/home/Carto"
GMAPIBUILDER="/Applications/Carto/gmapi-builder.py"
MKGMAP="/Applications/Carto/mkgmap/mkgmap.jar"
First, create img files from different layers
for f in $DIR/src/public/*.osm ; do
g=$(basename $f .osm) ;
d=$(dirname $f)
java -Xmx2G -jar $MKGMAP \
--transparent --add-pois-to-areas \
--keep-going --draw-priority=$drawpriority \
--description="[iero] "$g \
--family-name="iero Congo" \
--series-name="iero Congo" \
--mapname=$NAME --family-id=$ID --product-id=$ID \
--country-name=Congo --country-abbr=CG \
--style-file=$DIR/styles --style=iero \
--copyright-message="[iero.org] Congo $DATE" \
--product-version=$VERSION \
--latin1 --output-dir=$DIR/output/imgs/public $f 1> /dev/null;
cp $DIR/output/imgs/public/${NAME}.img $DIR/output/imgs/public/${NAME}.img
let NAME++ ;
let nbfiles++ ;
let drawpriority++ ;
done
Next, concatenate those files in unique img file
java -jar $MKGMAP --tdbfile --gmapsupp $DIR/output/imgs/public/*.img \
--keep-going \
--style-file=$DIR/styles --style=iero \
--family-name="iero Congo" \
--series-name="iero Congo" \
--description="[iero] Congo map" \
--mapname=$ORIGINALNAME --family-id=${ID_PUBLIC} --product-id=${ID_PUBLIC} \
--copyright-message="[iero.org] Congo $DATE" \
--product-version=$VERSION \
--output-dir=$DIR/output/gps/public 1> /dev/null;
Then, create gmapi files, ready for Basecamp :
python $GMAPIBUILDER -t $DIR/output/gps/public/osmmap.tdb -b $DIR/output/gps/public/osmmap.img -o $DIR/output/basecamp/mac/public $DIR/output/imgs/public/*.img
If you want to see the problem, final files can be downloaded in my website : http://www.iero.org/blog/2014/06/carte-du-congo/
Thanks !

I have done testing and only get the blank names with versions of mkgmap after they introduced the overview map feature. I built a map with r2585 and the name showed correctly.
