guess what i'm new to scripting

I have this assignment for shool and i'm stuck for hours now and clueless.
So if anyone could help me out, put me on the right track.

What i want to do is make a list for the current directory, then checking if it already exists if so ask the user if he wan'ts to overwrite, if no go back, if yes, overwrite the file.
At last if the file doesn't exist i want to create it and fill it up with the list from the directory.
This is how i failed

if [ -e dirdump.dmp ]; then
echo " The file already exists , overwrite? y/n "
read input
if [$input == "n"]; then
break
elif ["$input" = "y"]; then
ls >> dirdump.dmp
fi
else
ls >> dirdump.dmp
echo -n "U dump is aangemaakt en vind u terug in : "
pwd
fi

I get the following error: script.sh: 15 [y: not found

This is when i choose to type y.

Anyone?

You need spaces in the brackets, so

[$input == "n"] needs to be [ $input == "n" ].

You would probably be better off with a case or select statement.

See the "LinuxCommand" tutorial in my signature. It has a great section on BASH scripting.

I believe the previous posts will help solve your problem, but just to be a little picky,
when scripting, try and be consistent as it helps the next person reading your script to follow what is going on:

thanks for the quick response

I have solved it by using the advise that was given here.

The assigment is going well now!

Just a bit mystified. Doesn't ls >> dirdump *append* rather than overwrite?

Incidentally, does the script imply you haven't got the noclobber option set?

You can mark the thread as "[SOLVED]".
