Can please anyone help me. i have the following script:

#!/bin/bash

cache_query=$QUERY_STRING
xxx=`echo $cache_query | grep -o 'x=[0-9]*' | sed 's/x=//g'`;  
yyy=`echo $cache_query | grep -o 'y=[0-9]*' | sed 's/y=//g'`;
zzz=`echo $cache_query | grep -o 'z=[0-9]*' | sed 's/z=//g'`; 
let "zzz=18-$zzz"   
content_type=`echo $cache_query | grep -o 'type_image=[a-z]*' | sed 's/type_image=//g'`;
db_name=`echo $cache_query | grep -o 'db=[a-z]*' | sed 's/db=//g'`;     


echo "Content-type: image/"${content_type}
echo ""


case "$db_name" in
"genshtab" ) db_path="/home/bases/gena.sqlite";;
"yasat"    ) db_path="/srv/ftp/upload/yasat.sqlitedb";;
esac


echo "x = " $xxx "y = " $yyy "z = " $zzz "type = " $content_type "database = " $db_name "db_path = " $db_path; #оставляю на всякий $
./tget ${db_path} ${db_name} "/mnt/tmpfs" ${content_type} ${zzz} ${yyy} ${xxx}
cat /mnt/tmpfs/${db_name}/${zzz}/${yyy}/${xxx}.${content_type}

i wrote tget program on c, so if i write 

./tget /srv/ftp/upload/yasat.sqlitedb yasat /mnt/tmpfs png 17 0 1

in bash line everything go great, but if i try to call this program from bash script under apache http://46.182.21.31/?type_image=png&db=yasat&x=2&y=1&z=15 the program doesn't start and no errors in my log, is somebody have any ideas why?

    Did you try giving the full path of tget to get it executed from bash script? – vijayalakshmi d Feb 22 '15 at 22:48

  • Fix the query string parser and the [quoting](http://stackoverflow.com/questions/10067266/when-to-wrap-quotes-around-a-variable/27701642#27701642), then if you still cannot pull it off, try posting a new question with just the minimal case to reproduce your problem.
