after if isnt a reverse quote needed to indicate that it needs to be executed and then the output has to be provided to the if

I am a bit surprised when the command output is 0, then is executed. From C++ background, if the condition is boolean false or 0, it is skipped. In that situation you ave to handle the condition with == sign (ex if condition==false then do this) or if !condition then do this (here the condition is 0 or false)

#shell scripting on if-then statement
echo "Enter source and target filename"
read source target
mv $source $target
if [ $? -eq 0 ]
then
echo "Your file has been Successfully renamed"
fi

Thanks so much for the tutorials, but I'm using cygdrive (redhat) on windows 7, and there are such alot of commands that don't work and I get errors like this

Enter source and target file names
test newtest
': not a valid identifierrget
ss1.sh: line 7: syntax error near unexpected token `fi'
ss1.sh: line 7: `fi'
