1. The problem statement, all variables and given/known data:
Trying to run script but everytime I do I get teh following error message

Code:

line 4: [1: command not found

I have attempted different version but still come up with same results.


2. Relevant commands, code, scripts, algorithms:

Code:

#!/bin/bash
count=1
echo "start of the program"
while [$count -1e 10]
do
echo "Loop #$count"
sleep 10
count=$[count+1]
done
echo "end of the program"

3. The attempts at a solution (include all code and scripts):
I have attempted to change path to include directory of where script is located
I have ensured the script is executable
I have changed -1e to -i no change in affect


4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):

Code:

# wrong
while[$count -1e 10]

# right
while [ $count -le 10 ]

I've tried ...

Code:

while[$count -le 10]

with same results, but when I included the space before and after ...

Code:

while [ $count -le 10 ]

it worked. Why does that space matter?

It is a syntax rule.

The same reason you can't put enter keys anywhere you like. That's simply the way the language expects it.

Perhaps an interesting backgrounder is, that [ is one of the names of the 'test' utility (see ls -l /bin/[) and in this case it takes 4 parameters : $count, -le, 10, and ]
