The [ and ] test operators need white space around them: [ -f "$file" ] and so on — steeldriver, Feb 07 '17 at 19:00

It is very important to be careful about blank space between words in shell scripts. The problem with [ was already mentioned in the comments, but you have some other problems, too - the $ file and also echo"stuff with no space.

Also, you have some other problems. In case the filename contains a space, you should use quotes with all "$variable" references. I don't know why you thought u would work in if [$? -eq u] - the value will be 0, not u.
