Bad substitution issues.. but why?
i am trying to prepare a train and test dataset, for which i need to randomly split the data into corresponding folders (train,test)..

I began on a simple script, but seem to get som weird error messages, that i cannot make sense of?..

what am I doing wrong?
Code:
#!/bin/bash
RED='\033[0;31m'
NC='\033[0m' # No Color


if [[ $1 = "" ]]
	then
		echo -e "${RED}Missing Workspace name! -  Provide a name!${NC}"
	exit 1	
fi

if [[ $2 = "" ]]
	then 
		echo -e "${RED}Missing path to dataset - SPH files${NC}"
	#exit 1	
fi

if [[ $3 = "" ]]
	then 
		echo -e "${RED}Missing path to Utt!${NC}"
	#exit 1
fi		

WORKSPACE=$1
PATH_TO_DATASET=$2
PATH_TO_UTT=$3

#Create the folder 

mkdir ../${WORKSPACE}
 
cd ../${WORKSPACE}
ln -s ../wsj/s5/steps .
ln -s ../wsj/s5/utils .
ln -s ../../src .

cp ../wsj/s5/path.sh .

mkdir -p ../${WORKSPACE}/exp
mkdir -p ../${WORKSPACE}/conf
mkdir -p ../${WORKSPACE}/data
mkdir -p ../${WORKSPACE}/data/test
mkdir -p ../${WORKSPACE}/data/train
mkdir -p ../${WORKSPACE}/data/local
mkdir -p ../${WORKSPACE}/data/local/lang

# Modify if Help script is needed
#################################
# Change order of utterance and name! 
# python help_scripts/change_order_name_utt.py  /PATH/TO/UTTERANCE 

# Partition data randomly into train and test. 
SPLIT=0.5 #train/test split
NUMBER_OF_FILES = $(ls $PATH_TO_DATASET |  wc -l) ## number of directories in the dataset

for ((i=1; i<=$(NUMBER_OF_FILES); i++))
do
	ran = ${python -c "import random; print random.randdouble(0,1)"}
	echo ${ran}
done

output
Code:
../workspace_setup.sh: line 54: NUMBER_OF_FILES: command not found
./workspace_setup.sh: line 56: NUMBER_OF_FILES: command not found
./workspace_setup.sh: line 56: ((: i<=: syntax error: operand expected (error token is "<=")
