Capturing shell script command output

I am trying to check to see if a file exists on a ftp server, well, I know that cant be done, atleast directly, So I came up with this small script

Quote:

check_file

Code:

ftp -n $HOST <<END_SCRIPT
quote USER $USER
quote PASS $PASSWD
cd public_html/crap
dir $FILE
quit
END_SCRIPT

Where the $ variable have corresponding values, so if I run this on the promt as check_file > check.txt, I can then just check the file size for the check.txt file and know if the file exists or not. Well good deal, But I want to do the above check in the same script, for example, something like

Quote:

check_file_improved

Code:

{
ftp -n $HOST <<END_SCRIPT
quote USER $USER
quote PASS $PASSWD
cd public_html/crap
dir $FILE
quit
END_SCRIPT
} > $CHECK_FILE
if $CHECK_FILE = 0 {
  # file does not exist, lets upload the file to the server
  }
else {
  # file exists on the server, rename the file on server before uploading
  }

but somehow, I cannot capture any information into the $CHECK_FILE. Anyone ?
