I am messing with shell scripting and stuck in some comparison in while loop
while [$size -le $MAX]
do
------
done
The above loop is not working. What am I doing wrong ?

You don't have spaces around [ and ].
Say:
while [ $size -le $MAX ]
[ is a command, also known as test. When you say [$size, the shell interprets it as a string and not as a command.

Thaank u devnull and @dogbane for replying . That solved my headache. That little space raged me a bit.
You need spaces around the brackets, like this: while [ $size -le $MAX ].
However, it's more readable if you use bash's arithmetic expression instead:
while (( size <= MAX ))
do
done
