Your problem is this line:
Code:
if [ $FILECOUNT > 2 ]

To the shell it means: test ([]) the variable FILECOUNT for existence and if it has a value, and redirect any output to the file named '2' (> 2). If you're using the single bracket form of the tests, you'll have to use
  • -gt instead of >
  • -lt instead of <
  • -ge instead of >=
  • -le instead of <=
  • -ne instead of !=

You can get a list of all test operators by looking at the man page of test.

@dennis.jacob: the parameter '-1' to ls won't change anything. If ls detects that output does not go to a terminal it automatically switches to single-column mode. You can easily test that by running
Code:
ls | cat

in any directory.
