The following code snippet can be embedded in a bash script to ftp a file or script other ftp functions. It also includes error checking if the ftp of the file fails.

function ftpfile {
# failure or success flag
#
FLAG=0 # assume success
# Start the actual ftp of the file
RETUR=$(ftp -n <>${LOGFILE}
open $SERVER
user $USERNAME $PASSWORD
ascii
put file.txt
bye
EOF
)

# End of the actual ftp process
if [ "$RETUR" != "" ]
then
FLAG=1
fi
return $FLAG
#
}
# END FTP FUNCTION
# call function to ftp file
ftpfile $file
FLAG=$?
if [ "$FLAG" -eq "0" ]
then
echo "------> File transfer completed"
else
echo "------x File transfer failed"
fi
