heredoc error message in a shell script for FTP

Hello,

When I try to execute the following shell script:

#!/bin/sh
HOST='ftp.yourdomain.com'
USER='yourid'
PASSWD='yourpw'
FILE='file.txt'

ftp -n $HOST <<END_SCRIPT
quote USER $USER
quote PASS $PASSWD
ascii
get $FILE
quit
END_SCRIPT
exit 0

I receive this error message:

./my_script_name: line 7: cannot create temp file for here document: No space left on device

Line 7 is where the here doc begins with this string: <<END_SCRIPT

I know that I have sufficient space on the server from which I am running the script. What else should I look at to get it to work? I have, of course, substituted the values for HOST, USER, PASSWD, and FILE to my actual values and if I interactively FTP from the shell, I have not problem FTP-ing and getting the file.

Do you have permission to write to /tmp ? Or is that full ?

Sometimes people set /tmp to be read only for certain things, and sometimes /tmp is set to be non-execute which would cause these kinds of problems.

Try:

mount   (to check the permissions)
ls -ald /tmp
and
df -h (to check the space)
