Full Discussion: FTP error handling - critical

We are off topic here.

ftp provides return codes. It does not return an error to the shell normally. If you read the responses from ftp you can determine on a per file basis the status of each transfer.

Lets' start with this:
List of FTP server return codes - Wikipedia, the free encyclopedia

1nn == acknowledgement of your request
2nn == sucess
3nn 4nn == problems

This is a simplifcation, but it works for most situations
Since you are interested in all files, you have to track each file transfer and look for an error.
mput will give errors as well, plus when you use mput, you need the -i option
Code:
ftp -i -n

The reason for one-at-a-time is so you can pick up where you left off, plus I am assuming the files are large, so ftp reconnects take only a tiny amount of time compared to transfers.

Code:
#!/bin/sh
#
BACKUPDIR="/export/home/myuser/backup"
status=0
HOST='ftp.xyz.com'
USER='user@xyz.com'
PASSWD='abc'
#FILE='*.gz'

for FILE in *.fz
do
    status=0
    echo "Processing $FILE"
    ftp -n $HOST <<END_SCRIPT  | grep '^2' && status=1
    quote USER $USER
    quote PASS $PASSWD
    verbose
    lcd $BACKUPDIR
    cd backups/source
    binary
    put $FILE
    quit
    bye
END_SCRIPT
    if [[ $status -eq 0 ]] ; then
       echo "$FILE failed to transfer"
       break       # this makes the code end early
    else
      echo "$FILE sent ok"
    fi   
done
if [[ $status -eq  1 ]] ; then
   cd $BACKUPDIR
   rm *.gz
   echo 'successful completion'
else
   echo 'Failure.'
   exit 1                          
fi
exit 0

ftpd_selinux(8) 					 ftpd SELinux policy documentation					   ftpd_selinux(8)

NAME

       ftpd_selinux - Security-Enhanced Linux policy for ftp daemons.

DESCRIPTION

       Security-Enhanced Linux provides security for ftp daemons via flexible mandatory access control.

FILE_CONTEXTS
       SELinux requires files to have a file type. File types may be specified with semanage and are restored with restorecon.	Policy governs the
       access that daemons have to files.

       Allow ftp servers to read the /var/ftp directory by adding the public_content_t file type to the directory and by restoring the file type.

       semanage fcontext -a -t public_content_t "/var/ftp(/.*)?"

       restorecon -F -R -v /var/ftp

       Allow ftp servers to read and write /var/tmp/incoming by adding the public_content_rw_t type to the directory and  by  restoring  the  file
       type.  This also requires the allow_ftpd_anon_write boolean to be set.

       semanage fcontext -a -t public_content_rw_t "/var/ftp/incoming(/.*)?"

       restorecon -F -R -v /var/ftp/incoming

BOOLEANS

       SELinux policy is based on least privilege required and may also be customizable by setting a boolean with setsebool.

       Allow ftp servers to read and write files with the public_content_rw_t file type.

       setsebool -P allow_ftpd_anon_write on

       Allow ftp servers to read or write files in the user home directories.

       setsebool -P ftp_home_dir on

       Allow ftp servers to read or write all files on the system.

       setsebool -P allow_ftpd_full_access on

       Allow ftp servers to use cifs for public file transfer services.

       setsebool -P allow_ftpd_use_cifs on

       Allow ftp servers to use nfs for public file transfer services.

       setsebool -P allow_ftpd_use_nfs on

       system-config-selinux is a GUI tool available to customize SELinux policy settings.
