Deleting local server file from automated FTP script
Hi,

I want to delete a file on the local server, while connected to remote server through FTP.
I am using the below code for this

Code:
                        $FTP_CMD -v -n $HOST <<*! >> $LOGFILE 2>&1 
                        user $USER $PASSWORD
                        cd $DIR
                        put $mainfile
                        ls -l
                        !$RM_CMD /path/test/$file2del >> $LOGFILE 2>&1
*!

The FTP logs tell me that the file gets FTPed but the next command is invalid. Please let me know where I am going wrong.

The variables used are :
Code:
FTP_CMD=/usr/bin/ftp
RM_CMD=/usr/bin/rm

I doubt ftp understands your RM_CMD... You know ftp is a quite dumb type of shell, that only understand its own internal commands... look at the man pages, there is a delete, del command

But the same command works when I try to connect manually to the FTP server. And I also tried the delete command which is again not working.

I am using
Code:
#!/bin/ksh

Do we have any other alternative?

The issue is that RM_CMD is not environmental variable:

Code:
$ RM_CMD=/usr/bin/rm
$ echo $RM_CMD
/usr/bin/rm

$ ftp
ftp> !echo $RM_CMD

$ export RM_CMD
$ ftp
ftp> !echo $RM_CMD
/usr/bin/rm

Now the question I would have is why using the variable RM_CMD at all? Is there a problem with just specifying "rm"?

This code is giving the same error

Code:
$FTP_CMD -v -n $HOST <<*! >> $LOGFILE 2>&1 
                        user $USER $PASSWORD
                        cd $DIR
                        put $mainfile
                        ls -l

                        !rm /path/test/$file2del >> $LOGFILE 2>&1
*!

Apologies, wasn't paying attention, didn't notice the hereis document ... LS_CMD didn't need to be an environmental variable. But the leading spaces in front of the "!" are causing the problem:

Code:
$ ftp << eof
                               !rm foo >> bar 2>&1
eof

?Invalid command

But this works:

Code:
$ ftp << eof
!rm foo
eof

If you need the whitespace, try:

Code:
sed -e 's/^ *//' << eof | ftp hostname
    ....
eof
