Beginner at bash scripting - need help with passing arguments
I at the moment, making a simple bash script, capable of setting up an workspace for me, so i don't have to do it manually.. Problem is though i can't seem to provide the bash script any argument, without running into my error checks, checking for input...


Here is the code:
Code:
#!/bin/bash
RED='\033[0;31m'
NC='\033[0m' # No Color


if [[ $1 -eq 0 ]]
	then
		echo -e "${RED}Missing Workspace name! -  Provide a name!${NC}"
	exit 1	
fi

if [[ $2 -eq 0 ]]
	then 
		echo "${RED}Missing path to dataset - SPH files${NC}"
	#exit 1	
fi

if [[ $3 -eq 0 ]]
	then 
		echo "${RED}Missing path to Utt!${NC}"
	#exit 1
fi		

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

#Create the folder 

mkdir ../${WORKSPACE}

Here is the output I get:

Code:
./workspace_setup.sh start
Missing Workspace name! -  Provide a name!

Where start should be the first argument? - What is going wrong here?

tc-choke

TC(8)								       Linux								     TC(8)

NAME

       choke - choose and keep scheduler

SYNOPSIS

       tc qdisc ... choke limit packets min packets max packets avpkt bytes burst packets [ ecn ] [ bandwidth rate ] probability chance

DESCRIPTION

       CHOKe  (CHOose  and  Keep  for responsive flows, CHOose and Kill for unresponsive flows) is a classless qdisc designed to both identify and
       penalize flows that monopolize the queue. CHOKe is a variation of RED, and the configuration is similar to RED.

ALGORITHM

       Once the queue hits a certain average length, a random packet is drawn from the queue. If both the to-be-queued and the drawn packet belong
       to  the same flow, both packets are dropped. Otherwise, if the queue length is still below the maximum length, the new packet has a config-
       urable chance of being marked (which may mean dropped).	If the queue length exceeds  max,  the	new  packet  will  always  be  marked  (or
       dropped).  If the queue length exceeds limit, the new packet is always dropped.

       The marking probability computation is the same as used by the RED qdisc.

PARAMETERS

       The parameters are the same as for RED, except that RED uses bytes whereas choke counts packets. See tc-red(8) for a description.
