FTP in ksh script
Hi,

I'm trying to get "ftp" commands work inside a function written in ksh script; but it seems to be not working!!

Here's the code:
Code:
 
function chk_ftp_path {
IP_ADDR=$1
USER=$2
PASSWORD=$3
FTP_PATH=$4
 
ftp -ivn $IP_ADDR << EOF
user $USER $PASSWORD
cd $FTP_PATH
quit
EOF
 
valid_path=$?
.......
.......
}

When I run the main script (that calls the above function written in another script) then the script hangs after encountering "EOF"!! I don't know why? Please advice.

Comment out all code, and just print $1,2,3,4 and check if the value passed by you to function is properly reflected while calling?

Also, enable debugging using "set -x".

Hi psshah,

I am actually hard-coding those values in function (only for demo purpose I've shown function accepting values). So the values being passed to the function is not a problem. And I've enabled the debugging too....and this is what it displays!!

Code:
 
+ ftp -ivn ip_addr
+ 0<< \EOF
user user_name passwd
cd /remote/path
quit
EOF
............-> hangs until I press ^C

don't know what's happening!! Smilie

You said you are calling the script with the function from another script. You should capture what you pass to that script outside of the function, no?

I am also facing the similar problem in a shell script. Does anybody have the answer?

Can we see all the exact script(s) which matches the "set -x" trace.
The trace does not mention a function call.
The trace does not look like it came from "ksh". What Operating System and version is this?

Please check the script for invisible control characters:
Code:
sed -n l scriptname

Please check whether "ftp" is aliased.
Code:
alias | grep "ftp"

Please also try with verbose enabled:
Code:
set -vx

I am running the script on red hat Linux. I am calling the calling in normal shell.
Code:
     ftp -nv hostname <<SCRIPT1
            user $user $password
             cd  /location1
             mget *.txt
             bye
           SCRIPT1
                  -------> this is where its hanging 
    return_value=$?
    case return_value in
    0) echo 'successful file transfer' >> $path/return;;
    *) echo 'Error in ftp' >> $path/return;;
   esac

when I run the trace, its showing the following statements and i dont see the update to the file $path/return

Code:
Connected to Hostname
331 Password required for username.
230 User username logged in.
250 CWD command successful.
221
