I am new to shell scripting. I am using cygwin to run my scripts.
I ran this script from c:\shell

Here is the script i have.

cd //biz/stcurrentbuilds/1_0
f1=`dir`
echo $f1
f2=`dir`
echo $f2
while [$f1=$f2]
Do
f2=`dir`
echo "No new build"
done

When i run i get error
./ st.txt: line 10: syntax error near unexpected token `done'

Can someone please let me know what is wrong with my script?

Thanks,
