problem, with if condition in function
Hi All,

I have a function which reads parameter and gets the value from config file.

The entry in the file can be either of two
Name=value or
Name[variant]=value

so if the variant is not present it should return me the generic value ie Name without variant.

I am first searching for variant in the file and taking the count using grep, so if it is > 0 then search for variant else generic.

But if condition is not evaluating properly and is always treating it as 0.

Below is the function.................Please HELP ME.............


______________________________________________________________
function getProp () {
name=$1;variant=$2
var=$(grep -c \b"$variant"\b "$RUNNING_CONFIG_FILE")
if [ $var -eq 0 ];then
{
awk -F '([ \t]=)|(=)' '
BEGIN {
value=""
exitcode=0
}
/^[ \t]*#/ {next}
$1 ~ /'$1'$/{value=$2;exitcode=0}
END {print value}' "$RUNNING_CONFIG_FILE"
}
else
{
awk -F '([ \t]*=)|(=)' '
BEGIN {
value=""
OFS="="
exitcode=0
}
/^[ \t]*#/ {next}
/'$name'\['$variant'\]/ || /'$name'\[[ ]'$variant'[ ]\]/ { if (NF == 3) {value=$2"="$3} else {value=$2}}
END {if ("'"$3"'" ~ /NoSpace/) {gsub("(^[ \t]*)|([ \t]*$)","",value);print value} else {print value}}' "$RUNNING_CONFIG_FILE"
}
fi
}

SHAPE_STDVAR(7) 					 Miscellaneous Information Manual					   SHAPE_STDVAR(7)

NAME

       shape_stdvar - shapeTools RMS project wide variant definitions

DESCRIPTION

       This  file  contains common variant definitions to be used in a software development project supported by the shape release management sys-
       tem. The stdvar file defines a variant raster for a whole development project. This central definition  facility  unifies  the  naming  and
       semantics of supported system variants.

       Stdvar  is  to be included into the Shapefiles of any part of the developed system via shape's include mechanism. The definitions in stdvar
       should be carefully designed and maintained for each supported project. They usually concern variant  control  for  all	hardware/operating
       system platforms to be supported or variant settings to produce different qualities of generated code (debug or optimized).

       Enclosed  in  the shapeTools distribution, you find the stdvar file used in the development of the shape toolkit itself. This may be a good
       starting point for developing an own variant raster. At least, it helps you learning the definition syntax. Otherwise, for a description on
       the syntax of variant definition parts see the shape(1) manual.

FILES

       $(SHAPELIBPATH)/stdvar
