shell syntax error

Question

Anyone can help me what will be the problem? login name and password is from .netrc. , < before example.script wont work

  #!/bin/bash
  HOST='192.163.3.3'
  FILE="a.txt"

  while :; do
      ftp -p -v -i $HOST << example.script >> a.log
      grep -qF "Connected" a.log &&
      grep -qF "File successfully transferred" a.log && break
  done

  exit 0

example.script contains

 put $FILE
 quit

And the error is:

 ./example.sh: line 15: syntax error: unexpected end of file

I got this while I'm using sh -vx on my script:

  while :; do
  ftp -p -v -i $HOST < example.script >> a.log
  grep -qF "Connected" a.log &&
  grep -qF "File successfully transferred" a.log && break
  done
  + :
  + ftp -p -v -i 192.163.3.3
  + grep -qF Connected a.log
  grep: a.log: No such file or directory
  + :
  + ftp -p -v -i 192.163.3.3
  + grep -qF Connected a.log
  grep: a.log: No such file or directory
  + :

Note that this code fixes the problem (using < instead of << for the input redirection). The script file is given as exaple.script instead of example.script.

It seems you always make the same type of mistakes! You already made the same mistake 2 days ago in the post stackoverflow.com/questions/13600009/ftp-while-do-error — gniourf_gniourf

And perhaps you want > a.log 2>&1 and you might want to use ncftp or wget or curl — Basile Starynkevitch

Change your here document << which has nothing to do here! Instead, you mean:

ftp -p -v -i $HOST < example.script >> a.log

You need to close your here-doc :

#!/bin/bash
HOST='192.163.3.3'
FILE="a.txt"

while :; do
    ftp -p -v -i $HOST <<EOF example.script >> a.log
    grep -qF "Connected" a.log &&
         grep -qF "File successfully transferred" a.log && break
done
EOF

<< open a here-doc

But then you need to close the while loop too.

dont work :/ ./example.sh: line 14: syntax error: unexpected end of file

That's unlikely to be the solution; it shouldn't have been a here-doc in the first place. << was a typo for <.
